Wedge Lock Washers
Wedge-Lock Washers
TEC Series washers secure joints using tension rather than friction, as with traditional locking fasteners. TEC washers consist 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.
During installation, the radial teeth cause one half of the washer to be seated to the bolt or nut, while the other half is seated to the joint material.
When exposed to load 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 cams.
