TEC Series wedge-locking washers are recommended for applications where fasteners and washers may need to be removed and/or reused.
How TEC Series Washers Work
TEC Series washers are designed with cams on one side and radial teeth on the other. 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 subjected to load or vibration, traditional fasteners can loosen over time. However, with TEC Series washers, the radial teeth are firmly seated to the mating surfaces to prevent any movement in the loosening direction. This is where the unique cam design comes into play. The cam angle of the washers is greater than the thread pitch angle of the bolt, creating a wedge effect that prevents the bolt or nut from rotating loose. As a result, the clamp load is maintained, and the joint remains securely fastened.
