Tightening nuts are easy to install and reusable. Precision mechanical self-locking nuts with copper pins are widely used in machine tools, engineering, and other industries. The working principle of anti-slip locking nuts is to use the frictional force between the nut and bolt for self-locking. However, the reliability of this automatic lock is affected under dynamic loads. In certain critical situations, anti-loosening measures will be taken to ensure the reliability of the nut lock. The locking nut is one of the measures to prevent loosening. The quality of the locking effect of the nut mainly depends on the interaction force between the nut and the bolt. There are many ways to improve the interaction between the engaged threads, such as improving the structure of the nut threads and the surface treatment of the threads.

Development and inspection of anti-slip lock nuts, utilizing colorimetric technology to ensure screw accuracy at 4H, nut vertical accuracy between 0.002-0.005mm, guaranteeing the interaction force between mating screws. Conventional tightening methods require two nuts and a washer, but the vibration of the applicator causes the two-piece nut and washer to slowly separate, thereby reducing the locking effect. Precision lock nuts are combined with copper pins and the threaded part of the embedded nuts. When tightening the nut, the copper pin is compressed, then securely engaged with the external thread, effectively preventing loosening.
