9.2 Specifications on mounting onto a machine
9.3 Specifications on mounting on the gear output side
9.4 Tightening torques for common thread sizes in general mechanics
The specified tightening torques for headless screws and nuts are calculated values and are based
on the following conditions:
- Calculation acc. VDI 2230 (Issue February 2003)
- Friction value for thread and contact surfaces
μ =0.10
- Exploitation of the yield stress 90 %
