Lock Nuts Details
A locknut, also known as a lock nut, locking nut, self-locking nut, prevailing torque nut, stiff nut, or elastic stop nut, By design 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. Free-spinning locknuts exist which carry the advantage of not requiring extra torque until seated. A lock nut is an internally threaded fastener that possesses locking capabilities either by itself or in concert with another component.
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 that creates frictional interference between the threads of mating components. Locknuts are reusable a limited number of times as the prevailing torque declines each time the nut is used.

Locknuts lock fasteners in place to keep them from backing out or loosening due to vibration or torque. A locknut is commonly used in place of a standard nut on vibrating machinery and when joining soft materials. Types of locknuts include those with serrated flanges or tooth washers that dig into surfaces and those with nylon inserts or deformed threads that grip tightly onto fastener threads. Reversible locknuts (also called center locknuts) can be started from either side for flexibility with installation.
Lock Nuts are nuts that resist loosening under vibrations and torque. That’s why they’re used in automotive engines to reduce vibration and hold wheels tight against the axles. Some lock nuts have a nylon insert, which helps keeps the nut snugger against the bolt.
Also, our custom fastener, bolts, screws are widely used in the below industries
- Consumer products
- Heavy machinery
- Oil and gas
A wide variety of locking nuts are manufactured for a variety of applications
Nylon Inserts Lock Nuts
Nylon insert lock nuts– additionally referred to as nylon nuts as well as stop nuts– are a dominating torque, locking nut that withstands loosening caused by vibration and also typical usage. Unlike free-spinning hex nuts, lock nuts use a flawing flexible or metal product to remain in position versus torque and also shock. Nylon insert lock nuts are a prominent service for many applications, however, they are restricted to applications exposed to temperatures under 250 °.
How Does Nylon Lock Nuts Work?
Hex lock nuts use a nylon insert on top of the nut-producing stress in between the nut and also the threads of the breeding part. That’s why they are occasionally, confusingly, called nylon nuts, however they ought to not be puzzled with nuts made entirely of nylon.
As the nut is threaded onto a shaft or rod, it will rotate openly till the strings from the host part engage the nylon insert. The threads of the mating shaft will displace the nylon as well as develop resistance. This resistance stops the unintentional moving of the lock nut. The nylon in standard hex lock nuts can use, as well ends up being less efficient after duplicated removal as well as installation. For optimum holding power, change the nut if it needs to be removed throughout the disassembly of a component.
How to install nylon locknuts?
Jam nuts, or half nuts, are a low‑profile hex nut and account for half the elevation of a standard hex nut. Jam nuts are made use of as a locknut to prevent resonance from loosening a bolted joint. Before nuts were created with “self‑locking” capabilities, 2 jam nuts would be tightened up against each other to ensure that nuts will not loosen up over time.
How Do Jam Nuts Work?
Jam nuts make use of opposing rubbing versus either one more jam nut or a conventional hex nut to lock into placement on a threaded shaft or rod. There are contrasting viewpoints on which nut must be mounted initially. However, the most typical use instance involves the jam nut is tightened up down initially. The jam nut is complied with by the 2nd nut which is tightened or “jammed” versus the initial jam nut. It is tough to get both nuts properly torqued in this configuration, hence making it unfavorable for essential applications where the setup brings a stress load.
Bearing Lock Nuts
Bearing locknuts, sometimes called shaft locknuts or bearing retaining nuts, are used to safe bearings onto a shaft as well as are made to stop the helping to loosen of components because of vibration as well as rotation. Birthing locknuts have various looks from normal hex lock nuts. Bearing locknuts are normally rounded outside with keyed slots. This layout calls for a unique tool called a spanner wrench or socket to be set up or gotten rid of. Bearing locknuts are used in a wide range of applications, including the auto and agriculture sectors.
How Do bearing lock nuts work?
Bearing locknuts call for a favorable locking action, similar to castellated nuts, to secure place. Bearing lock nuts are mated with bearing lock washers to achieve securing capacities. The machined grooves despite the nut give a breeding surface for the flavors of the lock washer to fold up into, securing both parts in position.
