It is designed to spread the clamping load of a bolt or nut, reduce surface pressure, and help prevent the fastener from loosening over time. The zinc plating with clear chromate coating provides corrosion resistance, making it suitable for use in heavy-duty truck and equipment applications where reliable fastening is critical. Replace when a washer is missing, rusted, or deformed, usually during component reassembly.
