Notched washers are fasteners designed to increase adhesion between screws, nuts and contact surfaces, preventing loosening due to vibration or torsion.
Available in internal, external or combined toothing variants, they provide a self-locking effect that improves clamping stability.
Made of galvanised steel, inox and other alloys, toothed washers offer corrosion resistance and long service life, ideal for mechanical and industrial applications.
