M8 zinc plated disc spring washer Anti Loosening conical lock washer belleville washer DIN6796 with phosphate for bolted jointing
Disc spring washers are used to compensate for subsidence formation in screw connections and to prevent a loosening or unfastening of the connection. The locking effect is purely frictional.
The arched shape of these washers presses up against a bolt and down against a nut to prevent loosening from wear, vibration, or temperature changes. Similar to a spring, they flatten out as pressure is applied, helping to absorb shocks.
Zinc-plated washers have an outer layer of zinc that protects the inner steel from rust and extends the life of the washer. Similar to zinc plating, washers with a black phosphate coating are protected from rust in wet environments.
