Professional Applications & Engineering Value
This passivated 18-8 stainless steel flat washer delivers critical engineering solutions where corrosion resistance and mechanical integrity are paramount. The precision inch dimensions (0.156" ID x 0.375" OD) ensure optimal load distribution for No. 6 screw assemblies, preventing joint loosening and surface deformation in vibration-prone environments. The Rockwell B70 hardness provides exceptional wear resistance, making these industrial washers ideal for aerospace, marine, and chemical processing equipment where material degradation must be minimized. The passivation surface treatment enhances the natural corrosion resistance of 18-8 stainless steel, extending service life in humid or chemically aggressive conditions while maintaining dimensional stability across thermal cycles.
Specification Summary & Compliance
Manufactured to MS15795-806, NASM15795, and ASME B18.21.1 specifications with precise dimensional tolerances. The flat washer features inch system measurements with 0.156" inner diameter and 0.375" outer diameter, designed specifically for No. 6 screw applications. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and regulatory acceptance for global industrial use.
