FASTENER FUNCTIONING
Prior to learning the safe operating procedures for this tool, it is important to understand
how a powder actuated fastener works. A powder actuated fastener is considered to be
a direct drive or forced entry type of fastener because it is driven directly into the base
material. The driving action causes tremendous forces to be applied to the fastener.
DEWALT powder actuated fasteners are specially designed and manufactured to
withstand the forces imposed during the driving operation. Only fasteners manufactured
or supplied by DEWALT should be used in this tool.
FUNCTIONING IN CONCRETE
The performance of a powder actuated fastener when installed into concrete or
masonry base materials is based on the following factors:
1. Strength of the base material
2. Hardness and concentration of the aggregate
3. Shank diameter of the fastener
4. Depth of embedment into the base material
5. Fastener spacing and edge distance
In addition to these factors, installation tool accessories such as a stop spall, which
reduces the tendency of the concrete surface to spall during the driving action, can
increase the performance of the fastener.
When a powder actuated fastener is driven into concrete, it displaces the volume of
concrete around the embedded area of the fastener shank. As this occurs, the concrete
directly surrounding the fastener is compressed and in turn presses back against the
shank of the fastener. Additionally, the driving action generates heat which causes
particles within the concrete to fuse to the shank of the fastener. This combination
of compression and fusion holds the fastener in the concrete base material. A similar
action occurs when fastening into block masonry.
Generally, the performance of the fastener in a given concrete strength will increase
with greater embedment depths in a certain range. Depending on the fastener style
and base material strength, embedment depths range from 5/8" to 1-1/2". For depths
greater than this range, there is the possibility of fastener bending or fishhooking which
may decrease expected load capacities and create a safety hazard.
During the driving action, some localized surface spalling of the concrete may occur.
Normally, this is a surface effect which does not effect the performance of the fastener.
However, it may pose an aesthetic problem for exposed applications where a fixture is
not used. In cases such as this, two methods can be used to improve the appearance
of the fastener.
1. Another method used is to drive the fastener through a steel washer to improve the
appearance of the application.
2. A stop spall adapter mounted on the powder actuated tool can help to reduce
surface spalling.
FUNCTIONING IN STEEL
The load performance of a powder actuated fastener when installed into steel base
materials is based on the following factors:
1. Thickness of the steel
2. Tensile strength of the steel
3. Shank diameter of the fastener
4. Depth of point penetration through the steel
5. Fastener spacing and edge distance.

P35s EN 4
When a powder actuated fastener is driven into steel, it displaces the steel laterally
360˚ around the shank of the fastener. Since steel is an elastic material, it presses back
against the shank of the fastener to hold it in place. As the diameter of the fastener
shank is increased, the load capacity obtained will generally increase provided the steel
thickness is sufficient to accept the fastener. To further increase fastener performance
in steel, some fasteners have a knurled shank which allows the steel to form a key lock
into the grooves to provide higher capacities than those obtained with a smooth shank.
For optimum performance, the fastener point should completely penetrate the steel.
Normally, a minimum of 1/4" (6.35mm) is allowed for the point length. An increase
in performance can be expected until the fastener no longer completely penetrates
through the steel. At this point, the elastic properties of the steel cause a compression
force to be developed at an angle against the fastener point which reduces load
capacity. In thicker steel base materials, adequate load capacities may be obtained for
applications in which the point of the fastener does not fully penetrate the steel. Job
site performance tests are recommended.
Fasteners should not be used in areas that have been welded or cut with a torch
as these procedures may have caused local hardening of the steel. Over driving of the
fastener should be avoided as the rebound created may reduce the load capacity or
cause damage to the fastener. When fastening into unsupported long steel members,
it may be necessary to provide support in the area of the fastening to prevent spring
action which can cause inconsistent penetration and a reduction in load capacity.
SUITABLE BASE MATERIAL
While powder actuated fasteners can be used successfully in concrete, certain masonry
materials, and A 36 steel, some materials are completely unsuitable. Fasteners should
never be fired into hard or brittle materials such as cast iron, tile, glass, or rock. These
materials can shatter easily resulting in a potential safety hazard. In addition, soft base
materials such as wallboard, plaster, or wood are not appropriate as the fastener could
pass completely through these materials. The user should never guess when fastening
into any base material. Failure to follow the recommended installation and safety
guidelines can result in severe injury or death to the tool operator and/or bystanders.
CENTER PUNCH TEST
A center punch test should always be performed to determine the suitability of the base
material for a powder actuated fastening. This test is relatively simple and can help to
insure a safe, successful fastening. Be sure to wear safety glasses, goggles or a face
shield when performing this test. To begin, select the fastener to be used for the job.
Then, place the point of the fastener against the proposed base material. Strike the
fastener with a single hammer blow, then examine the point. If the point of the fastener
is not blunted and the base material has a clear point indentation, it is acceptable to
proceed with the first test installation.
Use of a powder actuated system is not recommended if the following occurs during
the center punch test:
1. The fastener point has been blunted. This indicates that the base material is too hard.
2. The base material cracks or shatters. This indicates that the base material is too brittle.
3. When using an average hammer blow, the fastener penetrates the base material
easily. This indicates that the base material is too soft.
FASTENER INSTALLATION REQUIREMENTS
It is important to understand the required minimum base material thickness
requirements along with the minimum spacing and edge distance requirements.
Failure to follow these requirements can result in an unsuccessful fastening and create
a safety hazard.

Concrete base material should be at least three (3) times as thick as the fastener
embedment penetration. If the concrete is too thin, the compressive forces forming at
the fasteners point can cause the free face of the concrete to break away. This can
create a dangerous condition from flying concrete and/or the fastener and also results
in a reduction of fastener holding power. For applications in the face shell of concrete
masonry block, select a fastener length which will not exceed the thickness of the
face shell.
FASTENER PENETRATION GUIDE
The following table lists typical embedment or penetration depths expected in the base
materials listed. The penetration will vary depending on the density of the material.
This table should be used as a guide since the consistency of these materials varies.
When in doubt, a job site performance test should be conducted.
DENSITY TYPICAL BASE MATERIAL PENETRATION
Soft Masonry Concrete Block 1" (26mm) – 1-1/4" (32mm)
Average Concrete Poured Concrete 3/4" (19mm) – 1" (26mm)
Dense Concrete Pre-Stressed/Pre-Cast Concrete 5/8" (16mm) – 3/4" (19mm)
EDGE DISTANCE
Do not fasten closer than 3" (76mm) from the edge of concrete. If the concrete cracks,
the fastener may not hold. Closer edge distances for applications such as sill plates
may be permitted if specific fastener testing has been conducted.
SPACING
Setting fasteners too close together in concrete or masonry can cause cracking. The
recommended minimum distance between fasteners is 3" (76mm) center to center.
FASTENER LENGTH SELECTION IN CONCRETE
For permanent applications using pins in concrete, first determine the thickness of the
fixture to be fastened. To this, add the required embedment or penetration into the base
material. This will be the fastener shank length required. For applications in the face
shell of masonry block, select a fastener length which will not exceed the thickness of
the face shell.
For removable applications with threaded studs, the shank length required is
equal to the embedment depth required. To determine the minimum threaded length,
add the thickness of the fixture and the nut / washer thickness. The nut and washer
thickness is equal to the nominal thread diameter. Do not over tighten threaded parts.
Maximum tightening torque values are listed in the table below. Use of a nut setter
is recommended to reduce the possibility of over tightening the fasteners. For critical
applications, perform a job site test.
MAXIMUM TORQUE FOR 1/4” STUD MAXIMUM TORQUE FOR 3/8” STUD

INSTALLATION IN STEEL
The following guidelines are based on the installation of a fastener in ASTM A 36
structural steel with the point fully penetrating the steel member. Recommended steel
material thickness ranges from a minimum of 1/8" (3mm) to a maximum of 3/8"
(10mm). For use in higher strength structural steel, applications where the point does
not penetrate the steel member, or a thickness of steel greater than 3/8" (10mm), job
site performance tests are recommended in accordance with ASTM E 1190.
BASE MATERIAL THICKNESS
Steel base materials should be a minimum of 1/8" (3mm) in thickness.
EDGE DISTANCE

P35s EN 6
For installations in A 36 steel, 1/2" (13mm) is the recommended minimum edge distance.
SPACING
The recommended minimum distance between fastenings is 1-1/2" (38mm) center to
center for installations in ASTM A 36 steel.
FASTENER LENGTH SELECTION IN STEEL
For permanent applications when using pins in steel, first determine the thickness of
the fixture to be fastened. To this, add the thickness of the steel base material plus a
minimum of 1/4" (6mm) to allow for proper point penetration. This will be the minimum
fastener shank length required. Do not select a fastener length longer than that required
for the application.
An excessively long shank can burnish or polish the hole created in the steel
resulting in a reduction in load capacity.
For removable applications with threaded studs, the shank length required is equal
to the thickness of the steel base material plus a minimum of 1/4" (6mm) to allow for
proper point penetration. This will be the minimum fastener shank length required. Do
not select a shank length longer than that required for the application. An excessively
long shank can burnish or polish the hole created in the steel resulting in a reduction
in load capacity. To determine the minimum threaded length, add the thickness of the
fixture and the nut / washer thickness. The nut and washer thickness is equal to the
nominal thread diameter.
Do not over tighten threaded studs, the maximum tightening torque is listed in
the table below. Use of a nut setter is recommended to reduce the possibility of over
tightening the fasteners. For critical applications, perform a job site test.

your responsibility to obtain proper training and a DEWALT operator card prior to using this tool in compliance
with the current American National Standard A10.3 Safety Requirements for Powder Actuated Fastening
Systems and the Federal Occupational Safety and Health Administration Standards (OSHA). Existing state or
local regulations should also be followed. When using this tool, you must have the qualified operators card in
your possession.
Revocation of card - Failure to comply with any of the rules and regulations for safe operation of powder
actuated tools shall be cause for the immediate revocation of your qualified operator card.
The following is a summary of safety precautions to be followed when operating a DEWALT powder
actuated tool. Failure to follow these safety instructions can result in serious injury or death to operators or
bystanders.
PRIOR TO OPERATING THE TOOL
1. Warning signs should always be posted within the area in which a powder actuated tool is to be used.
These signs should be at least 8” (203mm) x 10"(254mm) in size with boldface type that is not less
than 1"(26mm) in height. The sign should state "Powder Actuated Tool In Use"
2. Safety glasses, goggles or a face shield, required by ANSI/ISEA, should always be worn by operator
or bystander, to protect their eyes from flying particles. Hearing protection should always be worn by
the operator and bystanders when using a powder actuated tool. Other personal safety protection as
required should also be used.
3. Never modify or fabricate parts for use in your DEWALT tool. Use only DEWALT, loads, and tool parts.
4. Hands or other body parts must never be placed in front of muzzle/barrel. Accidental discharge can
cause piston and/or fastener to pass through the operator’s hand.
5. Never compress the tool against any part of the body. Serious injury or death may result in the event of
an accidental discharge.
6. Always point tool in a safe direction at all times.
7. Use the tool for its intended purpose only.
8. Any tool not in proper working condition must be immediately removed from service; tools must be
tagged ‘DEFECTIVE DO NOT USE’ until it has been properly repaired.
PREPARATION FOR LOADING THE TOOL
1. Tools must be checked prior to operating to make sure they are not fully or partially loaded with a
powder load or fastener.
2. To insure safe operation, perform the daily function test described in this manual. Be sure the tool is not
loaded prior to performing this test.
3. Do not operate this tool unless all its parts are in place and operating appropriately. Never attempt to use
a malfunctioning tool. Call 1-800-4 DEWALT for assistance.
4. Never guess about the suitability of a base material. If you are uncertain about the suitability of a base
material, perform a center punch test.
5. Do not operate the tool until you learn and understand the color code / numbering system used to
identify the power level of powder loads.
OPERATING THE TOOL
1. Only use fasteners and powder loads designed for this tool as supplied by DEWALT.
2. Do not use powder actuated tools in a flammable or an explosive atmosphere.
3. Do not fire a tool without a fastener. The piston will impact the work surface possibly causing serious

P35s EN 8
injury to the operator or bystanders along with damage to the tool.
4. Do not load the tool until you are ready to make a fastening. Check the power load level before inserting
it into the tool chamber.
5. Fastener must be loaded prior to loading the powder load, to prevent injury to operator or bystander in
the event of an accidental discharge.
6. Do not close tool against work surface. The tool should be manually closed, with hand away from
muzzle/barrel to prevent accidental discharge.
7. Hold the tool perpendicular to the work surface at all times. Use a spall guard wherever possible.
This will limit the possibility of fastener ricochet which could cause serious injury or death to the
operator or bystanders.
8. Always perform a test fastening with the lightest load level designed for use in the tool. If the lightest
load fails to set the fastener, try the next highest load until the proper level is attained. Failure to follow
this procedure may cause the fastener to be overpowered. If this occurs, the fastener may fully penetrate
the base material causing serious injury or death to someone. Overpowering the fastener can also
damage the tool, creating a safety hazard to both the operator or bystanders.
9. Do not fasten into cast iron, tile, glass, or other types of brittle materials. These materials can shatter
and create sharp fragments which may cause injury.
10. Do not fire tool within 3" (three inches) (76mm) of the edge of a concrete base material or within 1/2"
(one-half inch) (13mm) of the edge of a steel base material.
11. Do not attempt to install a fastener closer than 3” (three inches) (76mm) to another previously inserted
fastener in concrete or 1-1/2" (one and one-half inch) (38mm) in steel.
12. Do not fasten into a concrete base material less than 3 times as thick as the fastener penetration or into
a steel base material thinner than 1/8"3mm).
13. Never attempt to install a fastener in a cracked or spalled area in concrete. Place fastener at least 3"
(three inches) (76mm) away from a spalled area to prevent the possibility of the fastener bending and
striking an operator or bystander.
14. Do not attempt to install fasteners in areas that have been welded or cut with a torch as these
procedures may have caused local hardening of the steel.
15. NEVER attempt to drive fasteners through predrilled holes. Fasteners can deflect or ricochet potentially
causing serious injury to you or bystanders
16. If you decide not to make a fastening after the tool has been loaded, you must always remove the
powder load first followed by the fastener.
17. Never attempt to override the safety features of this tool.
HANDLING THE TOOL AND POWDER LOADS
1. Never leave a loaded tool unattended. Once the tool is loaded, make the fastening immediately or unload
the tool.
2. Always unload the tool before work breaks, changing parts, cleaning or servicing, and when storing.
3. To prevent accidental discharge of loads, never carry the powder loads in the same container as the
fasteners or other hard objects.
4. Always store the powder loads in the containers provided or in an enclosure provided for them. Never
intermix the various power levels. Keep them segregated in clearly identified containers.
5. NEVER use powder loads in firearms. Serious injury or death can occur.
6. Powder actuated tools and powder loads should always be stored under lock and key. Tools must be
unloaded when not in use.
TOOL MALFUNCTION
1. In the event that a load fails to discharge after the trigger is pulled, the tool must be kept depressed
against the work surface for a minimum of 30 (thirty) seconds in case of a delayed load discharge. Then
carefully remove the entire load strip. and dispose of it in a can of water or other nonflammable liquid.
Never attempt to force or pry a load out of a tool chamber.
2. Never discard unfired powder loads into a trash container.
3. Do not attempt to unload or disassemble a jammed, stuck or broken tool as improper handling may
cause it to discharge and strike operator and/or bystander. A jammed tool must be pointed in a safe
direction at all times. Tag the tool and lock it up. Call your DEWALT representative for proper assistance.

P35s EN 9
TOOL OPERATION
CAUTION: Be sure to read and understand all of the safety precautions and
training in this manual before attempting to operate the tool. (Check to be sure the
tool is not loaded, the piston moves freely within the barrel, and no foreign objects or
fasteners are in the barrel.) Perform the daily function test before using the tool.
OPERATION
1. Always load the fastener before inserting powder load to prevent injury to the
operator or bystanders in the event of an accidental discharge. Place the fastener,
point out, into the end of the guide until the fluted tip fits inside. Do not use
excessive force when inserting the fastener. If excessive force is required, stop
and determine why the fastener can not be inserted. Correct the problem before
proceeding.
Note: Do not use fasteners longer than 1-1/2" (38mm) as listed in the fastener
selection section of this manual.
2. Always point the tool in a safe direction away from bystanders and the operator. In
one movement, slide the barrel forward then close it against the stop. The barrel
should be pulled fully forward to reset the piston for the next fastening. Loss of
power may result from an improperly positioned piston.
Do not attempt to close the tool by exerting force on the front of the barrel. Never
place your fingers or hands over muzzle end of the tool. The safe position for hands
and fingers are as shown in the diagram. Hands must never be placed in front of
the tool muzzle or barrel. In the event of an accidental discharge, the piston and/or
fastener can pass through the operator’s hand.
3. Insert the powder load strip into the bottom of the tool handle starting with the
lowest power level, 3 / Green. The strip should be inserted completely and should be
flush with the bottom of the handle. Always insert the strip from the bottom of the
handle. If this load does not fully set the fastener, try the next higher power level until
the proper level is found.
WARNING: Over driving or over powering a fastener can cause a safety hazard.
4. To make a fastening, place the tool against the work surface. Hold the tool firmly
with two hands and completely depress the barrel. Then squeeze the trigger.
Always hold the tool perpendicular to the work surface. Hold the tool firmly against
the work surface to avoid excessive recoil. Never depress the tool against anything
except the work surface.
Note: In the event that the load does not discharge after the trigger is pulled, continue
to hold the tool depressed against the work surface for at least 30 (thirty) seconds
in case of a delayed load discharge. Then carefully remove the entire load strip and
dispose of it in a can of water or other non flammable liquid. Never attempt to force or
pry a load out of a tool chamber. Do not discard unfired loads into a trash container.
5. To prepare for the next fastening, point the tool in a safe direction. Always insert
a new fastener before loading or advancing the powder load strip. Insert the fastener
as described in Step 1. Once the fastener is inserted, cycle the tool as described in
Step 2. Repeat this procedure for subsequent fastenings. When the ten load strip
has been completely fired, remove it by pulling it from the top of the tool body.
WARNING: Do not attempt to unload or disassemble a jammed, stuck or broken
tool as improper handling may cause it to discharge and strike the operator and/or
bystander. A jammed tool must be pointed in a safe direction at all times. Tag the tool
and lock it up. Call your DEWALT representative for proper assistance.

REPLACING OR REPAIRING THE PISTON
The piston is an expendable part and must be replaced periodically. Typical signs of a
worn out piston are: breaking, bending or mushrooming of the piston.
Prior to servicing the tool make sure there is no powder load in the tool. Use caution
and do not lose or damage any tool parts.
1. Using a pin, lift the end of the annular ball spring and rotate toward the top of the
tool body. Pull the piston stop back and out of the tool.
2. Slide the piston guide and baseplate assembly out of the tool.
3. Using a fastener, pry the shear clip off the baseplate. Replace the shear clip if it is
damaged.
4. Remove the baseplate from the piston guide, then pull the piston out of the guide.
REASSEMBLY:
5. Tilt the baseplate and slide the fastener guide out. Press the guide out of the
baseplate using a piston if it does not slide out freely. Replace the guide if it is
damaged.
6. Clean the piston using a wire brush. Inspect it for worn or damaged piston ring,
chipped end, or bending. Apply lubricant to the piston shank to minimize piston
sticking from an overdrive condition. Wipe the piston dry.
7. If a piston tip is damaged, it can be shortened a maximum of 0.20 inches (5mm).
The tip of the piston should be ground flat and at 90 degrees to the shank of the
piston. The chamfer of the piston must also be reground as shown.Piston grinding
should be performed by qualified personnel using the proper equipment.
8. Press the piston into the end of the piston guide. Be sure to push it all the way
back into the guide. Ensure piston is positioned correctly in piston guide.
9. Insert the fastener guide into the baseplate.
10. Align the groove in both the piston guide and baseplate. Slide the baseplate (with
fastener guide) onto the piston guide. Press the shear clip into place. Insert the
piston guide and baseplate assembly into the liner in the tool body. Be sure to align
the groove with the opening for the piston stop.
11. Replace the piston stop and rotate the annular spring into place.
Upon reassembly of the tool perform the following test. Depress the tool against a flat,
hard surface and pull the trigger. The barrel assembly should slide smoothly inside the
tool housing assembly. The firing pin should release after the trigger has been pulled.
CAUTION: THIS TEST SHOULD BE PERFORMED WITHOUT A PIN OR
POWDER LOAD IN THE TOOL.

FUNCIONAMIENTO DEL FIJADOR
Antes de aprender los procedimientos de operación segura para esta herramienta, es
importante entender cómo funciona un fijador accionado por pólvora. Un fijador accionado

P35s ES 17
por pólvora se considera un tipo de fijador de accionamiento directo o de entrada forzada
porque se impulsa directamente dentro del material de base. La acción de impulsión
permite que se aplique una gran cantidad de fuerza en el fijador. Los fijadores accionados
por pólvora de DEWALT están especialmente diseñados y fabricados para resistir las
fuerzas impuestas durante la operación de impulsión. En esta herramienta, solo se deben
utilizar dispositivos fabricados o suministrados por DEWALT.
FUNCIONAMIENTO EN CONCRETO
El rendimiento de un fijador accionado por pólvora cuando se instala en materiales de base
de concreto o mampostería depende de los siguientes factores:
1. Resistencia del material de base
2. Dureza y concentración del agregado
3. Diámetro del vástago del fijador
4. Profundidad de incrustación en el material de base
5. Espacio entre el fijador y la distancia al borde
Además de estos factores, el rendimiento del fijador puede aumentarse mediante
accesorios para la herramienta de instalación, como un bloqueo contra astillas, que reduce
la tendencia a romperse de la superficie de concreto durante la acción de impulsión.
Cuando un fijador accionado por pólvora es impulsado dentro del concreto, este
desplaza el volumen de concreto alrededor del área incrustada del vástago del dispositivo.
Cuando esto ocurre, el concreto que rodea el fijador se comprime y, a su vez, se presiona
contra el vástago. Además, la acción de impulsión genera calor y esto hace que las
partículas dentro del concreto se fusionen con el vástago del dispositivo. Esta combinación
de compresión y fusión mantiene el fijador dentro del material de base. Una acción similar
ocurre cuando se instala en mampostería de bloques.
Por lo general, el rendimiento del fijador en una determinada resistencia del concreto
aumentará si se utiliza una mayor profundidad de empotramiento en un cierto rango. Según
el estilo del fijador y la resistencia del material de base, la profundidad de empotramiento
va desde5/8" a 1-1/2". Si empleará profundidades superiores a este rango, existe la
posibilidad de que el fijador se curve o se doble en la punta, lo que puede disminuir la
capacidad de carga esperada y crear un riesgo de seguridad.
Durante la acción de impulsión, puede producirse un astillado localizado de la
superficie en el concreto. Normalmente, este es un efecto de la superficie que no afecta
el rendimiento del fijador. Sin embargo, puede plantear un problema estético para
aplicaciones expuestas en las que no se utiliza un accesorio. En casos como este, se
pueden usar dos métodos para mejorar la apariencia del fijador.
1. Otro método utilizado consiste en impulsar el fijador a través de una arandela de acero
para mejorar la apariencia de la aplicación.
2. Un adaptador de bloqueo contra astillas montado en la herramienta accionada por
pólvora puede ayudar a reducir el desprendimiento de la superficie.
FUNCIONAMIENTO EN ACERO
El rendimiento de la carga de un fijador accionado por pólvora cuando se instala en
materiales de base de acero depende de los siguientes factores:
1. Espesor del acero
2. Resistencia a la tracción del acero
3. Diámetro del vástago del fijador
4. Profundidad de penetración de la punta a través del acero
5. Espacio entre el fijador y la distancia alborde
Cuando un fijador accionado por pólvora se instala en acero, el acero se desplaza
lateralmente 360˚ alrededor del vástago del dispositivo. Como el acero es un material
elástico, se presiona contra el vástago del fijador para mantenerlo en su lugar. A medida
que aumenta el diámetro del vástago del fijador, también suele aumentar la capacidad
de carga obtenida siempre que el espesor del acero sea suficiente para soportar dicho
dispositivo. Si se desea aumentar aún más el rendimiento del fijador en el acero, algunos
dispositivos tienen un vástago estriado que permite que el acero forme un bloqueo de
seguridad en las ranuras para proporcionar capacidades superiores a las obtenidas con un
vástago liso. Para obtener un rendimiento óptimo, la punta del fijador debe penetrar por
completo en el acero. Normalmente, se deja un mínimo de 1/4" (6,35mm) para la longitud
de la punta. Se puede esperar un aumento en el rendimiento hasta que el fijador ya no
penetre por completo a través del acero. En este punto, las propiedades elásticas del acero
hacen que se desarrolle una fuerza de compresión en ángulo contra la punta del fijador, lo
que reduce la capacidad de carga. En materiales de base de acero más grueso, se pueden
obtener capacidades de carga adecuadas para aplicaciones en las que la punta del fijador
no penetra por completo en el acero. Se recomiendan pruebas de rendimiento en el lugar
de trabajo.
Los fijadores no deben usarse en áreas que hayan sido soldadas o cortadas con un
soplete, ya que estos procedimientos pueden haber generado un endurecimiento localizado
del acero. No debe emplear un nivel excesivo de impulsión para el fijador, ya que el rebote
creado puede reducir la capacidad de carga o causar daños en el dispositivo. Cuando se
realice una fijación en componentes de acero largos y sin soporte, tal vez sea necesario
proporcionar soporte en el área de la fijación, ya que la acción de rebote puede hacer que
la penetración no sea uniforme y se reduzca la capacidad de carga.

MATERIAL DE BASE ADECUADO
Mientras que los fijadores accionados por pólvora se pueden usar sin problemas en bases
de concreto, algunos materiales de mampostería, el aceroA36 y ciertos otros materiales
son completamente inadecuados. Los fijadores nunca se deben instalar en materiales
duros o quebradizos, como hierro fundido, azulejos, vidrio o piedra. Estos materiales
pueden desmenuzarse fácilmente y generar un posible peligro de seguridad. Además, los
materiales de base blandos —como los paneles de revestimiento, el yeso o la madera—
no son apropiados, ya que el fijador podría atravesarlos por completo. El usuario nunca
debe hacer conjeturas cuando realice un trabajo de sujeción en cualquier material de base.
Si no se siguen las pautas de seguridad e instalación recomendadas, se pueden producir
lesiones graves o la muerte del operador de la herramienta u otras personas.
PRUEBA DE PUNCIÓN CENTRAL
Siempre se debe realizar una prueba de punción central a fin de determinar la idoneidad
del material de base para un fijador accionado por pólvora. Esta prueba es relativamente
simple y puede ayudar a garantizar una fijación segura y exitosa. Asegúrese de usar gafas
de seguridad, gafas protectoras o un protector facial cuando realice esta prueba. Para
comenzar, seleccione el fijador que se utilizará para el trabajo. Luego, coloque la punta del
fijador contra el material de base propuesto. Dé un solo golpe de martillo en el fijador y
luego, examine la punta. Si la punta del fijador no está desafilada y puede observarse una
hendidura en el material de base, puede continuar con la primera prueba de instalación.
No se recomienda usar un sistema accionado por pólvora si ocurre lo siguiente durante
la prueba de punción central:
1. La punta del fijador se ha desafilado. Esto indica que el material de base es
demasiado duro.
2. El material de base se agrieta o se quiebra. Esto indica que el material de base es
demasiado frágil.
3. Si aplica un golpe de martillo promedio, el fijador penetra fácilmente en el material de
base. Esto indica que el material de base es demasiado suave.
REQUISITOS DE INSTALACIÓN DE FIJADORES
Es importante comprender los requisitos mínimos necesarios para el espesor del material
de base, junto con los requisitos mínimos de espaciado y distancia al borde.
El incumplimiento de estos requisitos puede dar como resultado una fijación incorrecta y
crear un riesgo de seguridad.
ESPESOR DEL MATERIAL DE BASE
El material de base de concreto debe ser, al menos, tres (3) veces más grueso que la
longitud de penetración de la incrustación del fijador. Si el concreto es demasiado delgado,
las fuerzas de compresión que se forman en la punta del fijador pueden hacer que la cara
libre del concreto se desprenda. Esto puede crear una condición peligrosa, ya que se
pueden desprender partículas del concreto o el fijador, y también genera en una reducción
de la fuerza de sujeción. Para aplicaciones sobre el revestimiento frontal de bloques de
mampostería de concreto, seleccione una longitud de fijador que no exceda el espesor de
dicho revestimiento.
GUÍA DE PENETRACIÓN DE FIJADORES
La siguiente tabla enumera las profundidades habituales de incrustación o penetración
que se esperan en los materiales de base enumerados. La penetración variará según
la densidad del material. Esta tabla debe usarse como guía, ya que también varía la
consistencia de estos materiales. En caso de duda, se debe realizar una prueba de
rendimiento en el lugar de trabajo.
DENSIDAD MATERIAL DE BASE HABITUAL PENETRACIÓN
Mampostería blanda Bloque de concreto 1" (26mm) – 1-1/4" (32mm)
Concreto promedio Concreto vertido 3/4" (19mm) – 1" (26mm)
Concreto denso Concreto pretensado o prefabricado 5/8" (16mm) – 3/4" (19mm)
DISTANCIA AL BORDE
No aplique a menos de 3" (76mm) del borde del concreto. Si el concreto se agrieta, el
fijador tal vez no pueda sostenerse. Se pueden permitir distancias al borde más cercanas
en determinadas aplicaciones (por ejemplo, en placas de alféizar), siempre y cuando se
hayan realizado pruebas específicas de fijadores.
ESPACIADO
Si los fijadores se colocan demasiado juntos en superficies de concreto o mampostería, el
material puede agrietarse. La distancia mínima recomendada entre los fijadores es de 3"
(76mm) de centro a centro.

SELECCIÓN DE LONGITUD DE FIJADORES PARA CONCRETO
Para aplicaciones permanentes que usan clavijas en el concreto, primero determine
el espesor del montaje de sujeción. A esto, debe sumarle la medida de incrustación
o penetración requerida en el material de base. Esta será la longitud requerida para
el vástago del fijador. Para aplicaciones sobre el revestimiento frontal de bloques de
mampostería, seleccione una longitud de fijador que no exceda el espesor de dicho
revestimiento.
Para aplicaciones removibles con pasadores roscados, la longitud del vástago requerida
es igual a la profundidad de incrustación requerida. Para determinar la longitud mínima
de la rosca, sume el espesor del montaje de sujeción y el espesor de la tuerca/arandela.
El espesor de la tuerca y la arandela es igual al diámetro nominal de la rosca. No apriete
demasiado las piezas roscadas. Los valores máximos de par de apriete se detallan en la
siguiente tabla. Se recomienda usar un montador de tuercas para reducir la posibilidad de
apretar demasiado los fijadores. Para aplicaciones críticas, realice una prueba en el sitio de
trabajo.

INSTALACIÓN EN ACERO
Las siguientes pautas se basan en la instalación de un fijador en acero estructural
ASTMA36 con la punta introducida por completo en el componente de acero. El espesor
del material de acero recomendado varía desde un mínimo de 1/8" (3mm) hasta un
máximo de 3/8" (10mm). Para uso en acero estructural de mayor resistencia, aplicaciones
donde la punta no penetre en el componente de acero o un espesor del acero superior a
3/8" (10mm), se recomiendan pruebas de rendimiento en el lugar de trabajo según la
norma ASTM E 1190.
ESPESOR DEL MATERIAL DE BASE
Los materiales de base de acero deben tener un espesor mínimo de 1/8" (3mm).
DISTANCIA AL BORDE
Para instalaciones en aceroA36, la distancia mínima recomendada es de 1/2" (13mm).
ESPACIADO
La distancia mínima recomendada entre las fijaciones es de 1-1/2" (38mm) de centro a
centro para instalaciones en aceroASTMA36.
SELECCIÓN DE LONGITUD DE FIJADORES PARA ACERO
Para aplicaciones permanentes cuando se usan clavijas en el acero, primero determine
el espesor del montaje de sujeción. A esto, debe sumarle el espesor del material de base
de acero más un mínimo de 1/4" (6mm) a fin de permitir la penetración adecuada de la
punta. Esta será la longitud mínima requerida para el vástago del fijador. No seleccione una
longitud de fijador más larga que la requerida para la aplicación.
Un vástago demasiado largo puede bruñir o pulir el orificio creado en el acero, lo que
daría como resultado una reducción en la capacidad de carga.
Para aplicaciones removibles con pasadores roscados, la longitud del vástago requerida
es igual al espesor del material de base de acero más un mínimo de 1/4" (6mm) a fin de
permitir la penetración adecuada de la punta. Esta será la longitud mínima requerida para
el vástago del fijador. No seleccione una longitud de vástago más larga que la requerida
para la aplicación. Un vástago demasiado largo puede bruñir o pulir el orificio creado
en el acero, lo que daría como resultado una reducción en la capacidad de carga. Para
determinar la longitud mínima de la rosca, sume el espesor del montaje de sujeción y el
espesor de la tuerca/arandela. El espesor de la tuerca y la arandela es igual al diámetro
nominal de la rosca.
No apriete demasiado los pasadores roscados. El par de apriete máximo se detalla en la
siguiente tabla. Se recomienda usar un montador de tuercas para reducir la posibilidad de
apretar demasiado los fijadores. Para aplicaciones críticas, realice una prueba en el sitio de
trabajo.
