Professional Applications & Engineering Value
Engineered for demanding environments, these passivated 18-8 stainless steel flat washers deliver critical corrosion protection where moisture, chemicals, or temperature variations compromise fastener integrity. The precision 0.099" ID and 0.25" OD dimensions provide optimal bearing surface for No. 2 screw size assemblies, preventing loosening under dynamic loads. Meeting NAS1149-CN216R and AN960-C2L specifications, they are indispensable in aerospace, automotive, and heavy machinery applications where failure is not an option. The Rockwell C25 hardness ensures reliable performance in high-stress joints, while the passivated surface resists seizing during installation, reducing maintenance downtime and replacement costs.
Specification Summary & Compliance
This flat washer maintains tight dimensional tolerances per inch measurement standards, with internal diameter of 0.099" and outer diameter of 0.25". Manufactured from 18-8 stainless steel with passivated surface treatment, it conforms to NAS1149-CN216R and AN960-C2L specifications. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance across global markets.
