Professional Applications & Engineering Value

These passivated 18-8 stainless steel flat washers deliver critical engineering value by addressing common failure points in precision assemblies. The corrosion-resistant material and surface treatment prevent galvanic corrosion and chemical degradation, extending service life in moisture-prone or chemically aggressive environments. With exacting 0.099" ID and 0.14" OD dimensions, they eliminate play and ensure uniform clamping force distribution for No. 1 screw fastening systems. This precision prevents loosening under vibration and thermal cycling—common challenges in industrial washers for electronics, instrumentation, and aerospace components. The combination of MS51496-P79 specification compliance and controlled Rockwell C20 hardness provides reliable performance where dimensional stability and resistance to deformation are paramount.

Specification Summary & Compliance

Manufactured to MS51496-P79 standards with inch-system dimensional tolerances (ID: 0.099", OD: 0.14", Thickness: 0.010-0.013"). The 18-8 stainless steel construction with passivation meets precise flat washer requirements for No. 1 screw applications. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures adherence to hazardous substance restrictions and environmental safety protocols.
