* Strength classes for screws with untreated, non-
lubricated surface. Screw quality designations are
stamped on the screw heads.
8.8 = 8G
10.9 = 10K
12.9 = 12K
l Drum extension - drum
= 652 Nm
The values result in a 90% utilization of the
screw’s yield point at a coefficient of friction total =
0,14.Compliance with the specified tightening tor-
ques is checked with torque wrenches. When us-
ing MoS

lubricants the specified tightening
torques do not apply.
Self-locking nuts must always be replaced once
they have been unscrewed.
