9.3 Tightening torques for common thread sizes in general mechanical engineering
The specified tightening torques for headless screws and nuts are calculated values and are based
on the following conditions:
- Calculation in accordance with VDI 2230 (February 2003 version)
- Friction value for thread and contact surfaces µ=0.10
- Exploitation of the yield stress 90%
- Torque tools type II classes A and D in accordance with ISO 6789
The settings are values rounded to usual commercial scale gradations or setting possibilities.
 Set these values precisely on the scale.
