• High-strength performance with Grade 8 classification and Rockwell C38 hardness, ensuring reliability under heavy-duty loads
• Consistent thickness control (0.074-0.121") for uniform pressure application and vibration resistance
• Industry-standard compliance with ASME B18.21.1, guaranteeing dimensional accuracy and interchangeability
• Environmental responsibility through RoHS 3 and REACH compliance, meeting global regulatory requirements
• Optimized for 5/8" fasteners, providing secure fit and enhanced mechanical joint integrity

Professional Applications & Engineering Value

Engineered for demanding industrial applications, these Grade 8 flat washers deliver critical performance where vibration, heavy loads, and corrosive elements threaten joint integrity. The zinc yellow-chromate plated steel construction creates a robust barrier against rust and chemical exposure, while the Rockwell C38 hardness ensures maintained flatness under extreme compression. Perfect for heavy machinery assembly, structural steel connections, and automotive systems, these ASME B18.21.1 compliant washers prevent bolt head embedding, distribute clamping forces evenly, and eliminate galvanic corrosion risks in mixed-material assemblies.

Specification Summary & Compliance

Manufactured to ASME B18.21.1 dimensional standards with precise inner diameter (0.656"), outer diameter (1.312"), and controlled thickness (0.074-0.121"). The Grade 8 strength classification and Rockwell C38 hardness verify mechanical performance. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and global market acceptance.
