A locknut is a kind of nut, a part that is screwed together with a bolt or screw to fix it. This is the original part that all production machinery must use. The locknut is a component that tightly connects mechanical equipment. Next, Stud Bolt Supplier will introduce the method to prevent the nut from sliding:

Anti-loosening is to directly restrict the relative rotation of the lock nut pair through the lock nut stopper. Since the lock nut block has no pre-tightening force, the anti-loosening plug can only work when the lock nut is loosened to the stop position. Therefore, the lock nut cannot prevent loosening but can avoid falling.

After tightening, the riveting anti-loosening method uses punching, welding, bonding, and other methods, so the lock nut pair loses the characteristics of the movement pair, and the connection becomes a non-detachable connection. The forged bolt manufacturer tells you that the disadvantage of this method is that the bolt can only be used once, and it is very difficult to disassemble, and it must be destroyed before disassembling the bolt pair.

A positive pressure that does not change with external force is generated between the lock nut pair, thereby generating friction that can prevent the lock nut pair from rotating relative to each other. This positive pressure can be achieved by compressing the lock nut pair axially or in both directions simultaneously.
