Nut loosening principle

The DISC-LOCK locknut is composed of two parts, each of which has a staggered cam. Since the internal wedge design slope angle is greater than the nut angle of the bolt, this combination will tightly bite into a whole. When vibration occurs, the protruding parts of the DISC-LOCK locknut will stagger with each other, generating lifting tension, so as to achieve perfect anti loosening effect.

The working principle of the nut is to use the friction between the nut and the bolt for self-locking. However, the reliability of such self-locking will be reduced under dynamic load. In some important occasions, we will take some anti loosening measures to ensure the reliability of nut locking. Locking nut is one of the locking measures.
