Made of stainless steel, this washer is not only resistant to corrosion but hardwearing and robust so it can keep your fasteners and joints secure. This particular washer, with its internal teeth, helpfully lock into screws and bolts. It therefore prevents vibration or heavy weight from loosening the screw. This feature makes the washer highly effective and a great choice for homes and workplaces.

This washer is designed to be used with M4 screws and bolts. Its internal diameter is 4.3 mm, and its overall diameter is 8 mm. As the teeth are internal, they'll look discreet when in place.
