A spring washer is a type of washer designed to provide a spring force and absorb shock in bolted or threaded connections. It's typically a split ring, bent into a helical shape, that exerts a spring force between the fastener head and the bearing surface. This helps prevent the fastener from loosening due to vibration and maintains tension in the joint. 

A Star Spring Washer, also known as a Starlock Washer, is a type of washer characterized by its star-like shape, often with internal or external teeth. It's designed to provide a strong locking mechanism by creating friction between the washer, the nut, and the surface it's applied to, preventing loosening due to vibration or other forces.
