Property classes for screws with non treated, non greased surface. The screw’s quality marks appear on the
screw heads.
8.8 = 8G;
10.9 = 10K;
12.9 = 12K
The values give a 90 % utilization of the screw’s apparent yielding point at a coefficient of friction of
μ
total =
0,14.
Observance of the screw torques is controlled by torquemeter. When lubricant MoSo2 is used, the indicated
screw torques do not apply.
Note :
Always renew self-locking nuts after disassembly !
