Introduction
The PNT800L-PC is a small, lightweight tool for installing POP®brand POP NUT™ blind rivet nuts and other
blind threaded inserts by adjusting the setting force to the insert being installed rather than stroke like
traditional blind rivet nut tools. Controlling the setting force has the following benefits:
•No stroke adjustment is needed for the same nut in multiple application grips.
•Eliminated application & nut damage due to “double stroking”.
•Proper set achieved even with a small gap between the nut flange and Nosepiece.
Table 1 lists the POP NUT™ blind rivet nuts that can be fastened using this tool. The Nosepiece and Mandrel
must be changed to fit some sizes of POP NUT™. (See Table 5, Mandrel and Nosepiece Requirements table
in the Specification section)

Tool Operation
Loading the POP NUT™ onto the tool
1. Connect the air supply to the tool.
2. Thread the insert 1/4 turn onto the Mandrel.
3. Press the insert against the Mandrel as indicated and the Mandrel will spin, automatically
threading the insert onto the Mandrel.
4. Keep pushing the insert onto the Mandrel until the Mandrel stops spinning. If the insert is not
fully threaded, the setting stroke will be shortened by the gap between the head of the insert and
the Nosepiece.
Figure 9: Loading the POP NUT™ onto tool
Installing the POP NUT™ into the work piece
1. With the POP NUT™ mounted on the Mandrel, insert it perpendicularly into the hole of the work
piece
2. Pull trigger and hold it in order to install the insert
3. Keep trigger depressed until the Mandrel reverses direction and completely unthreads the
Mandrel from the insert.
4. Lightly pull the tool away from the work piece as Mandrel is reversing in order to disengage it
from the insert.
5. Once the tool is disengaged from the insert, release the trigger.*
Figure 10: Setting the POP NUT™
Note:
•Fit the flange of the insert flat against the work piece.
•Do not tilt the tool. The tool must be perpendicular to the work piece.

*Disengaging the tool from the insert
WARNING!
If you let go of the trigger during the installation sequence, the insert may not set completely, the
hydraulics will reset and the tool will not automatically unthread from the insert.
DO NOT pull the trigger again, follow the steps below to disengage the insert.
To disengage the tool from the insert and application:
1. Depress and hold the Control Knob (see Figure 12).
2. While holding the Control Knob, press and hold the trigger. This will cause the Mandrel to spin
counter-clockwise and unthread the insert.
3. When fully unthreaded, release the trigger.
To disengage the tool from the insert and work piece if the Mandrel is stuck:
1. Disconnect the air supply
2. Thread the M4 x 20 Cap screw provided with the tool, into the hole on the side of the Nose
Housing until if fits snugly against the inner Spin Pull Head, locking the rotatioin of the Mandrel to
the tool.
3. Turn the body of the tool counter-clockwise to detach it from the insert.

Setting Force Adjustment
•Verify the proper Valve Spring is selected – See “Setting Force Valve Spring Selection“
•Adjust the setting force of the tool according to insert size and thickness of work piece as
indicated in the instructions below.
•Test 5 pieces before beginning production work to ensure proper setting of the POP NUT™.
•Proper setting force is critical:
oLow setting Force results in insufficient stroke and clamping of the insert, leading to a
Spin Out failure in the application
oHigh setting force results in excess stroke and possible insert threads stripping and
Mandrel damage
Adjustment for Standard POP NUTs™
Use the following procedure to determine the proper setting requirments for the SPH, SFH, APH, AFH,
SPS, SFS, APS, AFS & SRH Series of POP NUTs™:
1. Determine minimum stroke, “SMin”, from the appropriate formula in the table for the POP NUT™
being used.
2. Set the insert in a test piece with the proper thickness
3. Measure the value of SMin and compare to the formula result.
Table 8: Stroke Formula for Standard POP NUTs™
Thread Size Stroke (SMin) Formula
M4X0.7 1.6+(N-t)-0.3
M5X0.8 2.0+(N-t)-0.3
M6X1.0 2.4+(N-t)-0.4
M8X1.25 RLT 2.4+(N-t)-0.4

Adjustment for ST & Thin Wall POP NUTs™
Use the following procedure to determine the proper setting requirements for the ST, TK, TL, TH Series
of POP NUTs™:
1. Determine the Installed Length, “IL” of the POP NUT™ being used. This information can be
found in the Emhart POP NUT™ Blind Rivet Nut catalog.
2. Set the insert in a test piece with the proper thickness
3. Measure the IL value after insertion and compare to the desired value
Figure 13: “IL” Measurement
IF… THEN…
IL (Measured) > IL (Desired) Increase setting force – See “Adjustment of Setting Force”
IL (Measured) < IL (Desired)
Check POP Nut threads for damage or sticking to Mandrel for 5 test pieces
•If okay, setup of tool is complete
•If damaged, Decrease setting load - See “Adjustment of Setting Force”
Adjustment of Setting Force
The following is the procedure for adjusting the Setting Force:
1. Loosen Socket Set Screw on Setting Force Control Valve.
2. Turn the Adjuster using a flat blade screwdriver as needed.
a. Adjust Setting force by 1/4 turn increments to prevent stripping or damaging of insert
threads.
3. Tighten Socket Set Screw on Setting Force Control Valve.
DESIRED EFFECT ACTION
Increase Setting Force (Increases Stroke) Rotate Adjuster Clockwise
Decrease Setting Force (Decreases Stroke) Rotate Adjuster Counter-Clockwise

Note:
•The stoke may increase or decrease due to changes in air pressure [~0.1 mm (0.004 in) per 0.1
MPa (15 psi)]
•Multiple work piece thicknesses
oWhen using the POP NUT™ tool to set the same insert in multiple work piece
thicknesses, adjust the setting force to accommodate the thinnest work piece.
WARNING!
Adjust Fastening Load Control Valve by 1/4 rotations.
If the Adjuster is rotated clockwise by a large amount to increase the setting force it may cause stripping
or sticking of Mandrel and/or POP NUT™ threads.
