A locknut, also known as a lock nut, locking nut, self-locking nut, prevailing torque nut, [1] stiff nut [1] or elastic stop nut, [2] is a nut that resists loosening under vibrations and torque. Prevailing torque nuts have some portion of the nut that deforms elastically to provide a locking action. [ 2 ]

What is Locknut? Locknuts are internally threaded fastener that possesses locking capabilities either by themselves or in concert with another component. By design, lock nuts are engineered to resist loosening when subjected to vibration or torque.

Lock nuts are used to locate bearings onto a shaft. Additionally, they can be used to mount bearings with a tapered bore onto tapered shaft seats and adapter sleeves, and to dismount bearings from withdrawal sleeves. Lock nuts are also frequently used to secure gears, belt pulleys and other machine components.

1 day ago · The locknut is also called a lock nut, locking nut, or prevailing torque nut. It is a nut that shows resistance for loosening if high pressure and torque are applied. Prevailing torque nuts come with some part that gets deformed for providing strong locking. In this post, we will cover details, features, and types of locknuts.

Oct 24, 2023 · There are essentially two lock-nut types: Lock nuts which use friction are designed with pitted or flanged grooves and need greater torque to tighten and loosen. They don’t spin freely along the fastener’s shaft, as they begin to clamp down as you rotate them. This means longer assembly time for your application.
