Serrated safety spring washers are also named as lock washers that solve the safety problem of bolt connections. Their exclusive performance is provided by their serrated surfaces.
The smoothly chamfered serrated surface is evenly pressed on the interface of bolt connection and safely presses the connecting parts to prevent their relaxation. The inside frication of serrated surface offers extra protection against relaxation.Toothed check washer includes S series and VS series, which can be used to prevent against the looseness of bolts incurred due to vibration by increasing the frictional resistance after the connection of washer and bolt.
