Strength classes for screws with untreated, non-lubricated sur-
face.
The values result in 90% utilisation of the apparent yielding point
at a friction coefficient µ = 0.14.
ges
Tightening torques are checked for correctness using torque
wrenches.
When using lubricant MoS2, the specified values do not apply.
Renew self-locking nuts after each removal.
