TEC Series
These reuseable, heavy-duty, self-locking Sherex® TECSeries™ Wedge Locking Washers are engineered for performance. Unlike traditional one-piece washers, TEC Series washers secure joints using tension rather than friction. Each Wedge Locking Washer consists of a pair of washers with cams on one side and radial teeth on the other. The cam sides are joined together with a mild adhesive, and installed between the bolt head and/or nut and the joint material. When exposed to load, shock, or vibration, the bolt or nut will attempt to loosen. Since the radial teeth are seated to the mating surfaces, any movement in the loosening direction is forced between the cam. Because the cam angle of the washers is greater than the thread pitch angle of the bolt, a wedge effect is created that prevents the bolt or nut from rotating loose.
