Serrated Washer

Serrated washers are also known as “Vibration Proof Washers”. Serrated washers have the unique feature of serrations on internal surfaces. When the final flattening of the safety washer occurs with the tightening of the screw, these serrations bite into the mating faces, thus preventing the loosening of the screw, nut, bolt, etc due to vibration. Serrated washers are ready to fit washer to sustain preload and avoid loosening. Due to the above feature serrated washers are also used in cable gland accessories. Serrated Washers fitted internally to the equipment and before a locknut act as an anti-vibration device to prevent the cable gland or other cable entry device and locknut. Particularly required in situations where vibrating heavy machinery such as mud, shakers vibrating machines or pumps, drilling.
