Disc-Lock

Disc-Lock washers by Sherex, also called wedge lock washers, are single use, heavy duty, self locking washers composed of a pair of washers featuring cams on one side and non slip ridges on the other. During installation, the washer is installed between a fastener and a work piece. When the fastener is exposed to load, vibration, or shock, it attempts to loosen. Any movement in the loosening direction is forced to the washer assembly creating a wedge effect that prevents the fastener from rotating loose.
