I would be very interested in any hard figures for this too. In the absence
of such data, I continue to use values that were common in my last company
- here we use mostly #2-56 screws of various lengths as fasteners to FR 4
boards and I tighten these to 1.8+/-0.2 inch  pounds. Some slightly larger
I take up to 2.5 inch pounds.

Hello,

Can anyone provide some general guidelines on the
torque requirement for mounting and fastening common
hardware onto FR4 materials with threaded steel
fasteners, lock washers and bolts?

Any table with starting values for common sizes and
screw types would be greatly appreciated.

Rgds,
Peter
