High-Quality 1/2 Inch Spring Washer from China Suppliers | Factory-Direct ANSI Steel Gasket Spring Pad

A spring washer provides excellent anti-loose and anti-seismic effects, helping to secure fastener connections under stress and vibration.

Typically, the general direction of the thread is right-handed, whereas the spiral direction of the spring washer is left-handed to counteract loosening forces.

After the nut is tightened, the flattening of the washer generates an elastic reaction that continuously compels and exerts force on the screw threads.

Vibration subjects the assembly to axial forces, causing elastic deformation in the components. This deformation can create temporary gaps between fasteners, making them prone to loosening.

The tip of the spring washer's oblique mouth presses directly against the supporting surface of the bolt or nut and the connected part. This design compensates for instantaneous gaps and effectively prevents loosening.
