HCT

HCT – HFER NUT
HEIGHT = 1,3d

THE PRINCIPLE

ONE HIGH HEXAGONAL SELF-LOCKING SLOTTED NUT ALL METAL

The principle of self-locking nut HCT is to compress the flank thread of the male element on one sector.

This principle is obtained by making a calibrated slot in the upper part located at 1/3 of the height of the nut (Height = 1,3 Diameter), which is then crushed under a specific load to obtain a permanent elastoplastic deformation.

When assembled, the HCT 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-locking). This self-locking torque is independent of the tightening torque applied when tightening the HCT nut.
