-NC is ordered without torque setting
by the customer.
If the torque pre-set cannot be modified by the customer any more, the screw of the setting
nut (component 1.5 or 2.5) has to be removed and coated with Loctite (average strength).
Afterwards tighten the screw at the tightening torque TA specified in table 2.
