The 316 stainless steel alloy provides enhanced welding capacity and durability compared to standard 18-8 stainless steel. Each washer features a 0.080" thickness, a 0.640" outside diameter, and a 0.296" inside diameter, designed to effectively distribute stress and span larger clearance holes. This product is supplied in a convenient gravity feed jar for easy dispensing. They are a key component in the Minerallac Type 316 stainless steel fastener line. The 70325SS316J flat cut washers are specifically designed to improve stress distribution across a surface. Their construction from 316 stainless steel, known for its excellent resistance to various corrosive elements, ensures longevity in challenging conditions. The precise dimensions of these washers, with an outside diameter of 0.640 inches and an inside diameter of 0.296 inches, allow them to effectively span larger clearance holes that might otherwise compromise the integrity of a connection. The 0.080 inch thickness provides the necessary material to handle the intended load distribution. The stainless finish further enhances their aesthetic appeal and protective qualities.
