Wave Washer

A wave washer is a thin, wavy spring washer that applies a light spring force when compressed. It is used to take up play and reduce vibration in assemblies.

A wave washer acts as a spring lock to keep components from shifting. It is used under a nut or bolt head to maintain constant pressure.

Wave washers are often made in spring steel or stainless steel. The material affects corrosion resistance and spring properties.

This is a general guide to checking this kind of part. It says nothing about any supplier's parts.

Ask for a certificate of conformance if you need to confirm the material and dimensions. On receipt, check the free height, thickness and inner and outer diameters. Check for cracks or deformation.
