Operating principle of locking ribs:
During tightening, the locking ribs "roll" the counter-material in the area of the bolt contact surface. This causes a plastic deformation that hardens the surface. No significant settling is determined at the end of tightening. The locking ribs limit the amount of settling of the connection and therefore reduce the loss of pretensioning force.
