SS Serrated Star Washer

An SS (Stainless Steel) Serrated Star Washer is a type of lock washer featuring multiple sharp-edged serrations (teeth) radiating from the center — either on the inside, outside, or both edges of the washer. These serrations bite into the surface of the material and the fastener head, providing superior grip and resistance to loosening caused by vibration, movement, or torque.

Function:

• Prevents loosening of nuts and bolts due to vibration or torque

• Provides electrical conductivity by breaking through surface oxides (in electrical assemblies)

• Ensures a firm grip between the mating surfaces

• Distributes load while maintaining tight joint integrity
