Professional Applications & Engineering Value
This USS flat washer delivers critical engineering value in heavy machinery, structural steel connections, and industrial equipment assembly. The 18-8 stainless steel material provides excellent resistance to rust, chemicals, and extreme temperatures, addressing common failure points in corrosive or high-stress environments. Its large 5" OD effectively distributes clamping force over a wider area, preventing surface indentation and maintaining bolt preload in 2 1/2" screw applications. The precise 2.625" ID ensures proper centering and alignment, reducing installation errors. Manufactured to ASME B18.21.1 specifications, this washer maintains dimensional consistency for reliable performance in construction, marine, and manufacturing applications where vibration resistance and long-term joint integrity are paramount.
Specification Summary & Compliance
This USS flat washer meets ASME B18.21.1 dimensional standards with 2.625" ID, 5" OD, and 0.210-0.280" thickness range. The inch system measurement ensures compatibility with standard 2 1/2" screw sizes. Material compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming environmental safety and restricted substance compliance for industrial applications worldwide.
