Washers secure joints using tension rather than friction, as with traditional locking fasteners. The 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 cam.
Because the cam angle (α) of the Wedge lock washer 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. The Clamp load is maintained and the joint remains secure.

Removal and reuse
Removing Wedge lock washer requires no special tools or procedures. Simply loosen the joint in the normal method and check the Washer to ensure the cam faces disengage.
While the Washers are typically reusable, they should always be inspected for deformation or excessive wear before reuse. If the Washers appear deformed or heavily worn, discard them use a new pair.
Quality
Each Wedge lock washer 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 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 that strictly adheres to multiple ISO certification standards, and is thoroughly tested through the production cycle to ensure a high level of quality.
