Professional Applications & Engineering Value
This passivated 18-8 stainless steel flat washer delivers critical corrosion protection and mechanical stability for demanding industrial applications. Its precise 0.149" ID x 0.375" OD dimensions and controlled thickness ensure perfect alignment with No. 6 screws, preventing loosening under vibration while distributing loads evenly. The Rockwell B70 hardness provides exceptional resistance to wear and deformation, making it ideal for aerospace assemblies, heavy machinery, and marine equipment where NAS1149-CN632R and AN960-C6 standards are mandatory. Engineers specify this washer to eliminate galvanic corrosion risks and maintain long-term fastener integrity in corrosive or high-temperature environments.
Specification Summary & Compliance
Manufactured to NAS1149-CN632R and AN960-C6 aerospace and industrial standards, this flat washer maintains precise inch-system dimensional tolerances for consistent performance. The passivated 18-8 stainless steel construction ensures corrosion resistance while meeting RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental compliance requirements. With a specified hardness of Rockwell B70 and thickness range of 0.028-0.036", it guarantees reliable service in regulated industrial and aerospace applications.
