Tightening torques
Torque values for metric coarse-pitch thread
Screws and nuts
The tightening torques specified below only apply if:
• A friction coefficient of μ
tot
= 0.14 is reached in connection with a
thread lubricant. A surface protection, for example A3C+L, Dacromet
or Termosil, is recommended for this.
• No other tightening torque is specified in the text.
• No additional screw locks, for example MK screws or a liquid screw
lock, are used.
