How does it work?
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.

Removal and reuse
Removing the Washers requires no special tools or procedure. Simply loosen the joint in the normal method and check the Washer to ensure cam faces disengage.
While the Washers are typically reusable, it should always be inspected for deformation or excessive wear before reuse. If the Washers appear deformed or heavily worn, discard and use a new pair.
Each the Washers manufacturing facility is led by a team of seasoned engineering professionals charged with ensuring all products meet stringent quality requirements. Our facilities are certified to ISO 9001-2015, IATF16949, and utilize high quality testing equipment, including tensile testing, accelerated corrosion salt spray testing machines, torque testing, standard measurement and gauging equipment.
The Washers are manufactured in a facility which strictly adheres to multiple ISO certification standards, and are thoroughly tested through the production cycle to ensure a high level of quality.
