General tightening torques of screws, nuts and bolts
The screw quality is stamped on the screw head, e.g. 8.8.
If the manufacturer’s specifications do not differ, the following torques
(average values) apply, depending on the screw quality:
Dimension Screw quality stamp Unit
8.8 10.9 12.9
M 4 2,7 3,8 4,6 Nm
M 5 5,5 8,0 9,5 Nm
M 6 9,5 13,0 16,0 Nm
M 8 23,0 32,0 39,0 Nm
M 10 46,0 64,0 77,0 Nm
Not all values can be applied to other manufacturers’ components. Read the
component manufacturer’s specifications or observe the torque specifications marked
on the components.
