These zinc-plated external tooth lock washers feature sharp teeth that bite into both the fastener and work surface to prevent loosening. The 5/16" internal diameter accommodates standard bolt sizes while the external teeth provide superior grip compared to smooth washers. Zinc plating offers corrosion resistance for indoor and outdoor applications. Ideal for machinery, automotive, and construction fastening where vibration resistance is critical.
