Spring washer is a mechanical fastening accessory designed to maintain tension in bolted assemblies and prevent loosening caused by vibration or dynamic loads. Typically made from high-quality spring steel, stainless steel, or other durable alloys, it features a slightly curved or split design that exerts a continuous elastic force between the bolt head (or nut) and the mounting surface.
