HCB

HCB – HFR NUT
HEIGHT = 0.8d

THE PRINCIPLE

ONE HEXAGONAL SELF-LOCKING SLOTTED LOW NUT ALL METAL

The principle of self-locking nut HCB is to compress the flank thread of the male element on a sector.
 
This principle is obtained by making a calibrated slot in the central part of the hexagon of the nut (Height = 0.8 Diameter), which is then crushed under a specific load to obtain a permanent elastoplastic deformation.
 
When assembled, the HCB nut returns to its original shape by generating pressure on the side of the flank of the male element on a sector creating a constant braking torque (called self-braking). This self-locking torque is independent of the tightening torque applied when tightening the HCB nut.
