Spring Washers also known as disc springs or Belleville washers, are a type of mechanical fastener used to prevent loosening or absorb shock and vibration between two surfaces. They are typically made from spring steel and have a conical or curved shape that provides a spring-like action when compressed. The spring washer works by flattening and compressing when a load is applied, which allows it to maintain tension on the bolt or nut and prevent it from loosening due to vibration or shock.
