Setting Tool Stroke
•Adjust the stroke 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 stroke is critical:
oInsufficient setting stroke results in insufficient clamping of the insert, leading to a “Spin
Out” failure in the application
oToo much setting stroke results in possible insert threads stripping and Mandrel damage
Stroke Adjustment
1. Loosen the M3 Lock Screw on the Control Nut using a 1.5mm Hex Wrench.
2. Set Stroke to the value of “E” as determined by the stroke formula below or from the POP NUT™
Stroke Charts.
3. Adjust the stroke by turning the Control Knob (¼ turn ~ 0.2mm)
a. Clockwise to decrease stroke
b. Counter-clockwise to increase stroke
4. Tighten the Lock Screw
5. Set a POP NUT™ and measure the “E” dimension.
6. Adjust the stroke to “E” +/-0.1mm
7. Set a POP NUT™ in a test piece with the desired
thickness and verify that the stroke is between SMin and
SMax.
8. Re-adjust stroke as necessary.
IF… THEN…
E (Measured) < E (Formula) Increase stroke – See “Stroke Adjustment”
E (Measured) > E (Formula) Check POP NUT™ threads and Mandrel for damage
Reduce stroke – See “Stroke Adjustment”
SMin (Measured) < SMin (Formula) Increase stroke – See “Stroke Adjustment”
SMax (Measured) > SMax (Formula) Check POP NUT™ threads and Mandrel for damage
Reduce stroke – See “Stroke Adjustment”

Stroke Setting 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 stroke minimum, “SMin”, maximum, “SMax”, and stroke setting, “E”, from the
appropriate formula in Table 6, Stroke Formula for Standard POP NUTs™, 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.

Stroke Setting 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™ or use the POP NUT™ Stroke Charts:
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

IF… THEN…
IL (Measured) > IL (Desired) Increase stroke – See “Stroke Adjustment”
IL (Measured) < IL (Desired) Check POP NUT threads and Mandrel for damage
Reduce stroke – See “Stroke Adjustment”
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)]
WARNING!
Adjust stroke Control Knob by 1/4 rotations.
If the Control Knob is rotated counter-clockwise by a large amount to increase the stroke, it may cause
stripping or sticking of Mandrel and/or POP NUT™ threads.
