Fasteners are used in a wide range of industries, including energy, electronics, electrical appliances, machinery, chemical industry, metallurgy, molds, hydraulics, etc. On various machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, chemical industry, instruments and supplies, etc., various fasteners can be seen. They are the most widely used mechanical basic parts. Their characteristics are that there are a large variety of specifications, different performance and uses, and the degree of standardization, serialization and generalization is also extremely high. Therefore, some people also call a type of fastener with existing national standards standard fasteners, or simply standard parts.

[0003] Most automotive fasteners are composed of bolts and nuts. Most of the existing automotive fasteners are locked by means of threads. Since the vehicle will vibrate during driving, the bolts and nuts are easily affected by the vibration of the vehicle, resulting in loosening of the threads between the bolts and nuts. Therefore, the locking performance is relatively low. Therefore, we propose a lockable automotive fastener. Content of the Utility Model
