Professional Applications & Engineering Value
These passivated 18-8 stainless steel flat washers deliver critical engineering solutions where corrosion resistance and dimensional precision are paramount. The MS51496-P71 compliance ensures they withstand vibrational forces and thermal cycling in aerospace, marine, and chemical processing equipment. Their 0.199" ID x 0.315" OD dimensions provide optimal bearing surface for No. 8 screws, preventing galvanic corrosion while maintaining clamp load integrity. The Rockwell C20 hardness guarantees minimal deformation under high torque applications, reducing maintenance intervals in conveyor systems, pump assemblies, and structural frameworks. By combining military specifications with RoHS 3 and REACH compliance, these washers address both performance demands and environmental regulations in global supply chains.
Specification Summary & Compliance
Manufactured to MS51496-P71 standards with inch-system dimensional tolerances. Features passivated 18-8 stainless steel construction with 0.199" inner diameter, 0.315" outer diameter, and 0.029-0.032" thickness range. Hardness maintained at Rockwell C20 for consistent mechanical properties. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, including SVHC provisions updated June 2023.
