Professional Applications & Engineering Value

These passivated 18-8 stainless steel flat washers deliver critical engineering solutions where corrosion resistance and mechanical reliability are paramount. The precision inch dimensions (0.938" ID x 1.75" OD) provide optimal load distribution, preventing surface deformation and maintaining joint integrity in heavy-duty industrial applications. The Rockwell B70 hardness ensures consistent performance under vibration and thermal cycling, while the passivated surface treatment creates a protective oxide layer that significantly extends service life in corrosive environments. These flat washers are engineered to meet the rigorous demands of aerospace, marine, chemical processing, and construction industries where fastener failure is not an option.

Specification Summary & Compliance

Manufactured to exacting inch system tolerances with internal diameter of 0.938" and outer diameter of 1.75", these washers maintain dimensional accuracy per MS15795-824, NASM15795, and ASME B18.21.1 standards. The thickness range of 0.108-0.160" ensures proper fit and function with 7/8" fasteners. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms environmental safety and restricted substance adherence for global industrial applications.
