DIN985 non-metallic insert lock nuts, also commonly known as nylon lock nuts, stop nuts, or self-locking nuts, are used to prevent threaded connections from loosening. They are widely used in various machinery, equipment, automotive, and construction industries, and are particularly effective in preventing screws from loosening in high-vibration environments.
The key feature of the DIN985 nylon lock nut is a nylon insert embedded in one end of the nut. This insert engages tightly with the threads as they pass through, generating friction to achieve a locking effect. This design effectively prevents the nut from loosening due to vibration and other factors while minimizing damage to the bolt, leading to its widespread use.
