HEXAGONAL SELF-LOCKING DEFORMED NUT ALL METAL ISO 7042
The principle of self-locking of the GSL nut is obtained by making calibrated marking on the top of the nut under a specific load.
When assembled, the screw generates pressure on the deformed thread of the nut creating a constant braking torque and independent (called self-locking) of the tightening torque of the latter.
