Product BrochureProduct Details:

The Washers secure joints using tension rather than friction,as with traditional locking fasteners.The Washers consist of a pair of the 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 forces between the cam.
Because the cam angle(α)of the Washers is greater than the thread pitch angle(β)of the bolt,a wedge effect is created by the cams,preventing the bolt or nut from rotating loose.Clamp load is maintained and the joint remains secure.
