Product Features


An internal tooth washer, also known as a star washer or toothed lock washer, is a type of washer that is used to provide a secure grip between the fastener and the mating surface. It is called an internal tooth washer because it has teeth on the inside of the washer that grip the surface of the bolt or screw head, preventing it from turning or loosening.


The teeth on the internal tooth washer dig into the mating surface of the material being fastened, creating friction that prevents the fastener from rotating or vibrating loose. This is particularly useful in applications where the fastener may be subject to vibration or movement, such as in machinery or automotive applications.



Widely used in machinery equipment, industrial production of shock absorption and insulation,can meet your different needs in daily life

A Lock washer exerts a spring force between the fasteners head and the substrate to create more friction and resistance to rotation
