Operation Process

The working principle of self-locking washers can be simply summarized as "frictional resistance". When the threaded connection is subjected to external force, the self-locking washer will generate a reverse frictional force to prevent the thread from loosening. This friction force is determined by the special structure and material of the self-locking washer.

The structure of self-locking washers is usually composed of a metal ring and a layer of elastic material. Metal rings are usually made of stainless steel or copper, and their surfaces have some protruding tooth like structures. These tooth shaped structures can increase the friction between self-locking washers and threaded connections. Elastic materials are usually made of rubber or plastic, and their function is to increase the elasticity of self-locking washers, making them easier to fit tightly with threaded connections.
