Sherex Warranty
Sherex Fastening Solutions FLEX-5S carries a 6 month warranty against defects that are
caused by faulty materials or workmanship. Sherex warranty period commences from the
date of delivery which is confirmed either by the invoice or delivery note. The warranty
becomes invalidated if the installation tool is misused or not serviced, maintained, and
operated according to the instructions in the Quick Start and Repair Manuals.

SAFETY
DO NOT USE THIS TOOL FOR ANY PURPOSE OTHER THAN THOSE SPECIFIED.
DO NOT USE ANY EQUIPMENT ALONG WITH THE TOOL THAT HAS NOT BEEN
RECOMMENDED OR PROVIDED BY SHEREX FASTENING SOLUTIONS.
▪Failure to do so could result in voided warranty and/or personal injury
THIS TOOL MUST BE KEPT IN EXCELLENT CONDITION AND SHOULD BE CHECKED
BY SPECIALIZED PERSONNEL ON A REGULAR BASIS TO DETECT DAMAGES AND
EVALUATE ITS OPERATING CONDITION.
ALWAYS DISCONNECT THE AIR SUPPLY BEFORE SET UP, ADJUSTMENT, OR
REMOVAL OF THE HEAD SET.
AIR INLET SHALL NOT EXCEED 7 BAR (102 PSI).
DO NOT USE THE TOOL WITHOUT OIL PLUG IN PLACE.

TOOL OVERVIEW
The FLEX-5S tool is designed for installing Sherex threaded insert/rivet nuts. The tool utilizes a pull to
stroke installation method. The advantage with this method is that the pulling distance of the tool can
be set to a specified distance ensuring the rivet nut insert is pulled to the same position (distance)
with each actuation of the tool. Contact Sherex for the conversion instructions for changing this tool to
a pull to pressure (FLEX-5P) installation method.
The tool is designed to install rivet nuts from M3 to M10 & #4-40 to 3/8-24. The recommended
operating air pressure is between 5 - 7 bar (72.5 - 101.5 PSI).

HEAD SET ASSEMBLY
ASSEMBLY INSTRUCTIONS
Choose the proper head set.
Remove the nose case, if still mounted.
Unscrew the adaptor nut while moving away the stop pins.
Insert hex driver 4into hex hole on spindle, place socket head cap screw (mandrel) 3on to
hex driver 4and reducing sleeve 5on mandrel 3.
Hold the adaptor nut, ensure the stop pins are seated in the last possible notch on the adapter
nut (may require you to turn forward 1 notch).
Screw on the nose case into the handle casting.
Screw on the anvil 1/2 onto the nose case.
To remove the equipment, do the reverse operation.
PLACING RIVET NUT ONTO MANDREL- LENGTH CHECK
Keeping the tool disconnected from air supply, place an insert on mandrel 3and adjust anvil 1
and lock nut 2 in order to match the insert and mandrel end. It is ideal to have 1-2 threads of
the mandrel protruding from the back of the rivet nut; this will ensure full thread engagement
during the installation process. Lock position by tightening lock nut 2 against the nose case.
Head sets should be serviced weekly. Any damaged or worn out parts should be replaced. Check
for mandrel wear and replace when necessary. Sherex recommends using high quality socket head
cap screws such as Unbrako® and Holo-Krome®.
IMPORTANT
DISCONNECT THE AIR SUPPLY WHEN SETTING UP OR REMOVING A HEAD SET.

STROKE ADJUSTMENT PROCEDURE
Determine the proper stroke distance of the tool based on the size
and style of rivet nut insert you are using for your application material
thickness. Contact Sherex should you require assistance determining
the appropriate stroke. Warning** A stroke setting that is too large for
the application may cause an over installed installation condition
which may damage the mandrel, the base material, and/or the rivet
nut insert.
Install the proper head set for the rivet nut thread size that
you will be using. Attach an air supply to the Air Inlet (1)
per the recommendations in this manual.
To adjust the stroke distance of the tool, use the key
provided with the tool and place it in the stroke adjustment
ring (3) located in the cut out of the back cover. The ring, when
threaded fully in, will pull to 1 mm (0.040”) of stroke. Turning the key counter-clockwise from one side
of the window to the other will increase the stroke approximately .12 mm (.005). Continue to adjust
the ring out until you have approximated the stroke distance required. Test by installing a rivet nut and
measuring the collapsed distance of the part. Adjust the ring as required to achieve the desired
installation distance. Note**Threading the adjustment ring beyond the 6 mm stroke may cause the
auto-reverse to not function. If this occurs, turn the adjustment ring in the opposite direction reducing
the stroke distance to 6 mm.
Thread an insert/rivet nut on to the mandrel (2) 1 or 2 turns. Apply pressure to the insert and the auto-
spin on feature will engage thereby spinning the rivet nut up the mandrel (2) until it comes in contact
with the anvil.
If during the set up process the tool does not automatically reverse out of the rivet nut press the
manual reverse button (4).
operation
Operating procedure
Head Set assembled, tool connected to air supply, stroke adjustment complete.
Screw the rivet nut onto the mandrel (2) a couple turns, then a light pressure on it will start the
spinning of the mandrel (push to spin) and automatically stop when the rivet nut comes in
contact with the anvil.
Insert fastener into the application.
Depress the trigger fully. This will place the insert and automatically reverse the tool out of the
installed rivet nut. (Depress the trigger and hold until auto-reverse engages). If auto-reverse
does not engage and insert has not collapsed, apply a manual pushing force to engage the
auto spin-on, and then depress the trigger. (Ensure the air pressure is within the specified
range).
If, at any time, manual-reverse (4) needs to be engaged, depress the button at the base of the
handle, to the right of the air inlet.
IMPORTANT
Do not push the mandrel without a rivet nut as this will cause the

MAINTENANCE
Servicing should be performed on a regular basis and a complete inspection will be needed once a
year or every 500,000 cycles, whichever comes first.
DAILY SERVICING
Every day, before use, pour a few drops of light lubricating oil on tool air inlet,
if the air supply is not equipped with lubricator.
Check for air leaks. If damaged, hoses and coupling should be replaced.
Make sure you are using the proper head set.
Make sure the pull stroke is correct for the selected rivet nut.
Check the mandrel for wear or damage and replace if needed.
WEEKLY SERVICING
Check for oil and air leaks.
MAINTENANCE
Every 500,000 cycles the tool should be completely checked and parts that are worn or damaged
should be replaced. O rings should be replaced and lubricated with Molykote®55M grease before
assembly.
Only a trained technician should service the Flex 5S tool. Should the Flex 5S tool require repair, the
tool can be sent to the Sherex authorized repair center:

• Place the tool on its side with the oil plug facing up.
• With a 5mm Allen key, unscrew the oil plug
• Fill tool with DEA Astron HLP 32 hydraulic fluid, or equivalent
•Gently rock tool back and forth to express any trapped air
•Return oil plug and tighten
•Connect air supply and cycle the tool multiple times
•Disconnect air supply and unscrew oil plug a few turns
•Re-tighten oil plug
•If, at any time, oil is leaking from the reservoir, replace the o-ring
located at the top of the threaded section.
