The 3/8 AN Washers SS 25pk from ALLSTAR PERFORMANCE is an essential component for automotive, aerospace, and precision mechanical applications. These washers are designed to provide a reliable and corrosion-resistant fastening solution, making them ideal for both professionals and hobbyists.
Engineered to distribute load evenly across bolted joints, these stainless steel flat washers help prevent fastener pull-through and protect underlying surfaces from damage. With a 0.375-inch inner diameter (ID) and a 0.624-inch outer diameter (OD), they offer optimal bearing surface for load distribution. Their 0.05-inch thickness balances rigidity with compatibility for standard AN hardware spacing requirements.
Engine builders, restoration specialists, and race teams will find these washers particularly beneficial when assembling carburetors, intake manifolds, valve covers, and fuel delivery components that require AN-standard fasteners. The natural finish of the stainless steel helps resist corrosion and oxidation, making them suitable for fuel systems and exposed engine bay applications.
