[0002] A nut is a nut that is screwed together with a bolt or a screw for fastening. It is a component that all manufacturing machinery must use. According to different materials, it is divided into several types such as carbon steel, stainless steel, and non-ferrous metals (such as copper). The working principle of the nut is to use the friction between the nut and the bolt for self-locking. However, the reliability of this self-locking will be reduced under dynamic loads. In some important occasions, we will take some anti-loosening measures to ensure the reliability of nut locking. Among them, using locking nuts is one of the anti-loosening measures.
