Self-Locking & Lock Nuts

A Locknut (self-locking nut, locking nut), is a nut which resists loosening through vibration and normal use. This trait makes them essential hardware for a multitutde of applications. Unlike free spinning nuts, lock nuts make use of a deforming elastic or metal material to stay in position against torque and shock. Other common names for lock nuts include locking nuts, prevailing torque nuts, stiff nuts, locknuts, or elastic stop nuts. Many lock nuts use a nylon insert for the uppermost thread which creates the friction necessary to create a lock against the properly sized mating component. Although lock nuts with elastic inserts are often re-usable, the amount of torque generated can lessen with use. Upgrade your lock nuts from among the high-quality selection available from G.L.
