Conical Washer

A conical washer, also known as a cone washer or a tapered washer, is a type of washer that has a tapered or conical shape. It is typically made of a flexible material, such as spring steel or plastic, and is designed to provide a secure hold and reduce friction between two surfaces. The tapered shape allows the washer to compress slightly when it is tightened down, creating a spring-like action that helps to maintain a constant pressure on the fastener and the material being fastened. This helps to prevent loosening due to vibration or torque and can also reduce wear on the fastener and the surrounding components. Conical washers are often used in applications where a secure hold is necessary, such as in the assembly of engines, gearboxes, and other mechanical components. They can also be used in electrical and electronic applications to help prevent the loosening of terminal connections.
