Before riveting any rivnut smaller than M8 or 5/6-18, you need to calculate the
working/compression stroke by using the chart and formula. Taking the M5 rivet
nut working on a 2 mm thick workpiece, for example, the calculation is as follows:
The working stroke = 13.1 mm (L) - 1.0 (k) - 8.0 mm (h) - 2.0 mm (e) = 2.1 mm
1. Open the handles and screw the rivet nut onto the mandrel clockwise
until it is completely on.
2. Pre-drill a hole in the workpiece, if needed, according to the size of
the rivet nut, and insert the rivet nut into the hole.
3. Close the handles to deform the rivet nut in the hole.
