And it is made of elastic materials such as high-quality steel, stainless steel, or copper alloy. Its structure is simple and installation is convenient. During installation, the nut should be tightened first, then the cotter pin should be inserted into the slot of the nut and the hole at the tail of the bolt. And the end of the cotter pin should be separated. It is applied in fields such as mechanical manufacturing, construction engineering, and the automotive industry. In mechanical manufacturing, it is used for the connection and fixation of mechanical equipment. In construction industry, it can enhance the stability and safety of the connection parts. Its special design prevents the nut and bolt from rotating relative to each other under impact, ensuring the stability of the connection. It uses the locking force generated by elastic deformation to prevent the threaded connection from loosening. When using, a corresponding material cotter pin suitable for the usage environment should be selected.
