S-92303A107 0.531" ID x 2" OD Oversized Washers

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments and outdoor applications
• Exceptional load distribution thanks to the 2" outer diameter, preventing surface damage and maintaining joint integrity
• Precision fit for 1/2" screws with 0.531" inner diameter, ensuring secure fastening and reducing installation errors
• Enhanced durability from Rockwell B83 hardness, providing excellent resistance to deformation under pressure
• Consistent thickness control (0.110-0.140") for uniform clamping force and reliable performance in repetitive applications
• Full regulatory compliance with RoHS 3 and REACH standards, guaranteeing safe use in regulated industries
• Long-term cost efficiency through reduced maintenance and replacement needs in demanding mechanical systems

Professional Applications & Engineering Value

This 18-8 stainless steel flat washer delivers critical engineering solutions where corrosion resistance and mechanical stability are paramount. The combination of precise 0.531" ID for 1/2" screw compatibility and generous 2" OD creates optimal surface coverage, effectively distributing clamp load across connected components. This prevents stress concentration, surface indentation, and joint loosening in heavy-duty applications including machinery assembly, structural frameworks, and marine equipment. The Rockwell B83 hardness ensures the washer maintains its structural integrity under sustained pressure and vibration, while the stainless steel composition provides reliable performance in corrosive environments where carbon steel washers would degrade prematurely.

Specification Summary & Compliance

Manufactured to inch system specifications with precise dimensional tolerances, this flat washer features 0.531" inner diameter, 2" outer diameter, and thickness ranging 0.110-0.140". The 18-8 stainless steel construction meets industry standards for mechanical fasteners with Rockwell B83 hardness rating. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and restricted substance control for global industrial applications.
