Hexagon nut is the most commonly used one. Lock nut is the unified name of all nuts with locking function, which has a better anti-loosening effect than ordinary hex nuts.
The working principle of lock nut is to realize the self-locking function through the interaction of friction force and pre-tightening force, and to improve its anti-loosening effect through special structure and materials.
The nylon lock nut can be reused. Because the nylon material has insufficient resilience after being extruded, so locking effects are not as good as those of the initial installation.
Under normal circumstances, lock nuts are right-handed threads like standard nuts. They are tightened when rotated to the right. However, there are also some left-handed threaded nuts, which are mainly used for frequently rotating connectors. The reverse thread can prevent the nut from being affected by rotational force. Causes loosening.
