Double Sided Lock Washers

Double sided lock washers consist of two identical washers, each with a structure with beveled teeth on one side and a certain non-slip texture on the other. The beveled teeth of the two washers are mounted opposite each other, and during bolt tightening, the beveled teeth bite into each other. This friction then plays a certain auxiliary role in preventing the nut from loosening under normal conditions. When an external force tries to loosen the nut, the friction and the resistance of the helical teeth cooperate with each other. For example, in a working environment with vibration, such as the operation of an engine, the vibration of the equipment will cause the bolt to be subjected to alternating loads. At this point, the friction between the washer and the nut and connected parts can resist part of the loosening tendency caused by vibration. At the same time, the biting effect of the oblique teeth further strengthens the anti-loosening effect and ensures the tightness of the bolt connection.

Double sided lock washers are widely used in a variety of machinery and equipment, such as automotive, marine, aerospace, petrochemical and other fields. In these fields, double-sided lock washers can not only ensure the stability and safety of the connection, but also improve the operational efficiency and life of the equipment.
