[0002] A nut is a fastener with internal threads, typically used in conjunction with bolts, screws, and other externally threaded components to secure connections and transmit loads. They are usually made of metals such as steel, stainless steel, and copper, and can be categorized by structure into hexagonal nuts, square nuts, lock nuts, etc. During operation, the threads engage to generate a tightening force, preventing the connection from loosening. Nuts are widely used in machinery manufacturing, construction engineering, and the automotive industry. Their dimensional accuracy and thread strength directly affect the stability and safety of the connection structure, making them an indispensable basic component in modern industry.

[0003] An integrated self-locking nut is a fastener that integrates fastening and anti-loosening functions. It is an optimized design based on the traditional nut structure, eliminating the need for additional anti-loosening accessories. Self-locking is achieved through improved thread structure. After assembly, it uses structural interference or friction to prevent thread loosening. It can maintain fastening stability even under complex working conditions such as vibration and impact. It is widely used in machinery, automotive, aerospace and other fields, and is especially suitable for scenarios with high anti-loosening requirements and limited assembly space, simplifying the installation process and improving connection reliability.
