A lock washer with internal teeth, also known as an internal tooth lock washer, is a type of fastener used to prevent loosening or rotation of a bolt or nut. It has a circular shape with internal teeth that bite into the surface of the bolt or nut, creating friction and resisting movement. The internal teeth provide a locking effect, helping to secure the fastener in place and prevent it from vibrating loose. Internal tooth lock washers are commonly used in various applications, such as automotive, machinery, and construction.
