• High-strength performance with Grade 8 classification and Rockwell C38 hardness for demanding applications
• Precise compatibility with 1 1/2" screw sizes, ensuring secure fastening and vibration resistance
• Reliable dimensional accuracy manufactured to SAE inch system and ASME B18.21.1 standards
• Environmental compliance meeting REACH regulations for safe use in global industrial supply chains
• Enhanced durability from plated steel construction, resisting wear in high-stress assemblies

Professional Applications & Engineering Value

This Grade 8 flat washer delivers critical engineering solutions where high-strength and corrosion resistance are paramount. The zinc yellow-chromate plated steel construction combats oxidation in outdoor, marine, or chemical-exposed settings, while the SAE inch dimensions (1.625" ID x 3" OD) provide optimal load spreading for 1 1/2" screw sizes. Ideal for heavy machinery, structural steel connections, and automotive assemblies, it prevents joint loosening under dynamic loads. Its Rockwell C38 hardness and ASME B18.21.1 compliance ensure consistent performance in industrial washers applications, reducing maintenance costs and downtime.

Specification Summary & Compliance

Manufactured to ASME B18.21.1 specifications with inch-system dimensions: 1.625" internal diameter, 3" outer diameter, and 0.136-0.192" thickness range. The Grade 8 fastener strength and Rockwell C38 hardness guarantee mechanical reliability. Fully compliant with REACH (EC 1907/2006) regulations, containing no SVHC above threshold limits as of 06/14/2023, ensuring environmental and safety standards are met for industrial distribution.
