Note
Friction value
For the contact surface of the screw head and the screw thread, the friction value µ
tot
= 0.1 is
taken as a basis.
• For smaller friction values, you must reduce the tightening torque and for larger friction
values you must increase the tightening torque.
• Also note the maximum tightening torques of the screws used. These may be lower than the
values specied in the table above.
