Self Locking Nuts
A self-locking nut is a nut that resists loosening under vibrations and torque. Elastic stop nuts and prevailing torque nuts are of the particular type where some portions of the nut deform elastically to provide a locking action.
Their locking action is created by the distortion of their uppermost threads and should resist loosening caused by shock, vibration, and other forces. They host a self-contained feature which creates frictional interference between the threads of mating components.
Safety lock nuts are reusable with a limited number of times as the prevailing torque declines each time the nut is used. The self-locking nut offers an easier and more cost-effective solution to protect against vibration-related loosening. Using just one lock nut, manufacturing companies can secure multiple objects together without fear of vibrations loosening the nut. Even under heavy vibrations, they will remain stable and secure to the bolt on which they are used.
The special shape of the thread of the safety lock nut effectively prevents failure and at the same time reuses the nut. Also, the number of components is reduced by the self-assurance of the mother, since no further security elements are needed. The screw lock counteracts the unintentional release, without the need to process the screw itself.
