lubricated surface. The quality designation of the
screws is stamped on the screw heads.
8.8 = 8G
10.9 = 10K
12.9 = 12K
The values result in a 90%ige utilization of the
screws yield point, at a coefficient of friction of tot.
= 0,14.
The compliance with the specified tightening tor-
ques is checked with torque wrenches.
