Strength classes for bolts with untreated, unlubricated surface. The
bolt quality designation is evident on the screw heads.
8.8 = 8G ; 10.9 = 10K ; 12.9 = 12K
The values result in a 90% utilisation of the screw yield strength, in the case of
a coefficient of friction
μ ges. = 0.14.
Adherence to tightening torques is checked with a torque wrench. When using
lubricant MoSo2, the specified tightening torques do not apply.
NOTE
Self-locking nuts must be renewed after dismantling!
