2-2 SCREW parameters
When a assembly is in use, external influences generally increase the tensile strength in the screw (F
1
> F
0
).
With correct installation, RIVKLE
®
exhibits the same behaviour as a standard nut.
Results:
1. BÖLLHOFF recommends a setting force higher than the screw tensile strength after clamping, in order to ensure that
no re-setting occurs during the life of the RIVKLE
