Dominating torque securing nut (Stover lock nut)

It has a securing system that’s developed into the cone, as you put it on, it begins to imitate a securing nut, its self-contained attribute creates frictional disturbance between the strings of the mating elements. When attaching a prevailing torque lock nut, there is a resistance to rotation throughout both assembly and also disassembly needing them to be dragged; that resistance is called dominating torque. They can be changed or removed after installation.

Hex jam nuts

Hex jam nuts

The jam nut is usually utilized with an additional nut together, you ought to tighten them up against each other, that’s why they called jam nuts and how they work. They can likewise be made use of in a limited location where a full-sized nut can not be completely placed.

Keeps K-Lock nut

K-Lock nuts have little wings around, which is movable, it’s a free-rolling washing machine lock nut, when the wings obtain tightened, note not to over tighten it, due to the fact that when you over tighten the nut, it’s no longer a lock nut, and that cost-free rolling washing machine obtains crushed, it does not benefit you any longer.

Nylon insert lock nuts

Nylon insert lock nuts

This kind of lock nuts have a layer of nylon insert inside of the nut, when you placed the screw through, it starts to string the nylon, then it puts pressure on the screw as well as prevents it from vibrating loosened and also diminishing. The nylon insert nut includes an internal nylon washing machine or spot, the enhancement of non-metal product makes the nut much more conscious of temperature as well as chemicals. To install the nylon insert lock nuts, a tool is called for.

Castle lock nut (Castellated nut)

Castle lock nuts are a kind of nut with slots cut into one end, normally made use of in low-torque applications, such as holding a car wheel bearing in place, you can discover them on axles when they hang on wheels as well as bearings.


A lock nut is a special kind of nut that won’t loosen up even exposed to resonances, according to the numerous applications, a vast range of lock nuts come in different layouts. A lock nut additionally referred to as a locknut, locking nut, as well as a self-locking nut, is a kind of fastener that is made use of to secure bolted joints and also withstand loosening under resonance as well as torque. There are various selections of locking nuts, such as the steel nut, which employs steel to develop friction, and also the nylon inserts lock nut, which incorporates a polymer in the layout versus loosening.

There is a small mark in the center position on the exterior of the nut, practically like a punch right in the center, that reveals it’s a two-way nut, as the name suggests, this kind of nut is securing in two methods, whether you put it on or off, once you start to screw up to that dimension, it will begin to lock.
