Double-tooth disc spring lock washers are available in Series S and Series VS. The unique performance of tooth-faced disc spring lock washers is provided by their toothed surface, which solves the safety issue of
bolted connections. After the washer is connected to the bolt, it prevents the bolt from loosening after vibration by increasing frictional resistance.
DIN9250, JB/ZQ4340
During assembly, the inner inclined tooth surfaces face each other, and the outer radial convex surfaces engage with the contact surfaces at both ends. When the connected part is subjected to vibration and the bolt tends to loosen, only the inner inclined tooth surfaces of the two washers are allowed to move relative to each other, generating lifting tension, thus achieving a 100% locking effect.

Because the molecular arrangement of stainless steel changes after cold heading and cold rolling, resulting in slight magnetism. However, this is only a physical property, and its chemical properties remain unchanged.
