Overview

The Minerallac 70720SS316 is a 1/4" x 1" Type 316 stainless steel fender washer designed to distribute load across wood or lightweight sheet metal. Its large outer diameter relative to the central hole provides 3-4x more surface area than standard washers, reducing material damage and improving joint integrity. Constructed from Type 316 stainless steel, this washer offers exceptional corrosion resistance against chlorides, sulfides, and harsh chemicals, making it ideal for marine, industrial, and electrical applications. The washer is supplied in jars of 100 units and is manufactured in the USA. Common uses include securing panels, fenders, and structural components where vibration resistance and long-term durability are required. The increased surface area also enhances welding capacity in metal fabrication applications.
