Product Features


Internal star lock washer, also known as a star lock washer or internal tooth lock washer, is a type of washer that is designed to prevent nuts and bolts from loosening due to vibration or other forces.


Internal star lock washer has a star-shaped interior that provides teeth-like projections around the inner circumference of the washer. These teeth-like projections are designed to dig into the material surface of the nut or bolt head, providing a secure grip and preventing it from rotating or vibrating loose.
