A Spring Washer (also known as a Split Washer) is a type of washer designed to provide tension and prevent loosening of fasteners due to vibrations or torque. It is typically made from materials like steel, stainless steel, or carbon steel and has a split or spiral shape. When compressed, the washer exerts a spring-like force that helps maintain the tightness of the bolt or nut, ensuring a secure connection. ...
