Wedge Lock Washers

Wedge Lock Washers

Disc-Lock and Tec Series by Sherex are two-piece lock washers that use a wedges or cams to provide tension to an assembly that prevents loosening when under load.

Disc-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.

TEC Series washers are a two piece, pre-assembled, two piece wedge locking washer. The pair of joined washers feature cams on the mating face and ridges on the other. The two washers are joined with a mild adhesive on the cam side of the washer and installed between conventional threaded fasteners and a joining substrate. TEC washers use tension to secure a joint rather than the frictional force that is applied by traditional washers.
