Tightening torques for metric standard
threads
The tightening torques specified below apply only if:
– a coefficient of friction of µ tot = 0.14 is reached in
connection with thread grease.
To achieve this, surface protection such as
A3C+L, Dacromet or Termosil is recommended.
– no other tightening torque is specified in the
descriptive text.
– no additional screw locking such as microencap-
sulated bolts or liquid locking compound is used.
