Split lock washers

Split lock washers also known as spring lock washers, split lock washers are characterized by a break point. Unlike flat washers, they don’t consist of a solid and flat piece of metal. Rather, split lock washers are broken or “split.” This unique design means that one side of a split washer is higher than the other side. Split washers are made by “splitting” a ring of metal, followed by twisting the metal.

Split lock washers, also known as spring washers or helical spring lock washers, are a type of hardware used in fastening applications to help prevent the loosening of threaded components due to vibration or dynamic loads.

How to use the split lock washers:

1. Place the split washer between the nut/bolt head and the surface being fastened.
2. Tighten the nut/bolt with the desired torque. As the nut/bolt is tightened, the split washer compresses slightly, generating spring force and friction.
3. The generated friction helps resist any tendency for the nut or bolt to rotate due to external forces.
