Tightening torques of screws, nuts and bolts
Use only suitable tools for tightening screwed components, e.g. torque
wrench, otherwise the screws may shear off.
Parts may be damaged if the screws are over-tightened.
Always observe the specified torque.
Observe the minimum screw depth. In the case of hard aluminium alloys this must
be minimum 1.4 x screw diameter (e.g. nominal diameter M 5 x 1.4 = 7 mm).
According to the current state of the art, all screws, nuts and bolts that
are relevant to safety should be tightened with a torque wrench.
This indicates the corresponding torque in Nm (Newton meter).
