A locknut, also known as a lock nut, locking nut, self-locking nut, prevailing torque nut, stiff nutor elastic stop 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 portion of the nut deforms elastically to provide a locking action.The first type used fiber instead of nylon and was invented in 1931.

Three advantages of lock nuts:

First, superior anti-vibration performance: When the thread is tightened, the thread of the screw crest of the bolt tightly enters the 30 ° wedge-shaped slope of the nut and is clamped. The axis is at an included angle of 60 °, rather than an included angle of 30 °. Therefore, the normal force generated when the lock nut is tightened is much greater than that of a standard nut, and it has a great ability to prevent looseness and vibration.

Second, wear resistance and shear resistance are strong: the 30 ° bevel of the thread of the nut thread can evenly distribute the nut's locking force on the threads of all the teeth. Because the pressing force on the thread surface of each tooth is evenly distributed, The nut can better solve the problems of thread wear and shear deformation.

Third, good re-use performance: A large number of use shows that the locking force of the lock nut is not reduced after repeated repeated tightening and disassembly, and the original locking effect can be maintained.
