Cup Washer

Description

A cup washer, also known as a cupped washer or a cupped spring washer, is a specialized type of washer with a concave shape resembling a shallow cup. This design allows the washer to provide a larger bearing surface while also acting as a spring, exerting pressure against the surface it is installed on and the fastener it secures. Cup washers are commonly used in applications where vibration resistance and secure fastening are required, such as in automotive, machinery, and construction industries. They are often used in conjunction with bolts or screws to distribute the load over a larger area and prevent damage to the surface being fastened. Cup washers come in various materials and finishes, including steel, stainless steel, and brass, to suit different environmental conditions and aesthetic preferences.
