Vibration Proof Lock Washers
Zinc Flake Coated

For use with Grade 5, Grade 8 & ASTM 574 High Grade Bolts.

These washers have cams or wedges on one side, a lead angle greater than a thread angle, and radial teeth or ribs on the other side. The washers are installed cam face to cam face. When tightening the fastener to preload, the teeth penetrate and seat
against the joint material and the nut and/or fastener head. When subjected to vibration the interacting cams create a wedge action which prevents the fastener from vibrating loose.
