Professional Applications & Engineering Value

Engineered for demanding industrial environments, these 316 stainless steel flat washers provide critical protection against corrosion and chemical degradation. The inch-system dimensions (0.344" ID × 2" OD) ensure precise fit with standard 5/16" fasteners, while the controlled thickness range (0.052-0.072") delivers consistent load distribution across mating surfaces. This flat washer design solves common engineering challenges in chemical processing, marine equipment, and offshore applications where saltwater, acids, and harsh chemicals would rapidly degrade ordinary washers. The 316 stainless steel composition offers superior pitting resistance compared to standard grades, making these washers ideal for critical assemblies requiring long-term reliability in corrosive environments.
