Maintenance :
Strength classes for screws with untreated, unlubricated surface. The screw quality designation is indicated on the
screw heads.
8.8 = 8G ; 10.9 = 10K ; 12.9 = 12K
The values result in 90% utilization of the screw yield strength, with a coefficient of abrasion of
µ
total = 0.14.
Adherence to the tightening torque levels is checked using a torque wrench. When using lubricant MoSo2, the
specified tightening torque levels do not apply.
Remark :
Self-locking nuts must be renewed after dismantling !
