Professional Applications & Engineering Value
These passivated 18-8 stainless steel flat washers deliver critical corrosion protection in demanding applications where environmental resistance and dimensional precision are paramount. The MS51496-P87 compliant design ensures reliable performance in aerospace, marine, and industrial equipment where 3/4" screw assemblies require consistent load distribution. The passivation surface treatment creates a protective oxide layer that significantly enhances corrosion resistance compared to untreated stainless steel, making these flat washers ideal for applications exposed to moisture, chemicals, or extreme temperatures. Their precise inch-system dimensions (0.813" ID x 1.125" OD) guarantee proper fit and function in critical fastening systems.
Specification Summary & Compliance
Manufactured to MS51496-P87 military specifications with dimensional tolerances maintained within 0.013-0.019" thickness range. The 18-8 stainless steel construction features Rockwell C20 hardness for consistent mechanical properties. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and unrestricted global distribution. Designed specifically for 3/4" screw applications in inch measurement systems.
