Two of these washers form a pair. If the bolt becomes loose, the cam of one of the washers pushes up the cam of the other washer, and a force that tries to separate the washers is generated. However, because of the wedge effect, the washers will not separate more than screw pitch. Indication of the drawingThe wedge angle α is greater than the screw lead angle β. The loosening of bolt can be effectively prevented by the wedge effect. Results of vibration testTest method：Yanker type vibration testThe result is better than other vibration test. In the case of incomplete screwing down, bolt can be tightly fastened.
