Our Zinc Plated Internal Tooth Lock Washers are a practical fastening solution for applications where added security and a cleaner appearance are required. These washers feature internal serrated teeth that bite into the underside of the bolt head, screw head, or nut, helping to create a locking effect that resists loosening during use.
The zinc plated finish offers added corrosion resistance, making these washers suitable for a wide range of general engineering, maintenance, automotive, and industrial applications. Because the teeth are positioned on the inside diameter, they remain hidden under the fastener head, making these washers ideal where a more discreet, low-profile finish is preferred.
