Professional Applications & Engineering Value
These USS flat washers with black corrosion-resistant coated steel construction provide essential protection against rust and degradation in demanding industrial environments. The 2.625" ID x 5" OD dimensions create an optimal bearing surface that distributes clamping force evenly, preventing material deformation and maintaining bolt tension in heavy machinery, structural steel connections, and large-scale equipment assemblies. The ASME B18.21.1 compliance ensures dimensional accuracy and mechanical reliability, while the corrosion-resistant coating significantly extends service life in outdoor, marine, or chemical exposure conditions where standard washers would fail prematurely.
Specification Summary & Compliance
This USS flat washer features precise dimensional specifications including 2.625" inner diameter, 5" outer diameter, and thickness ranging 0.210-0.280" for consistent performance. Manufactured to ASME B18.21.1 standards for dimensional accuracy and mechanical properties. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance in global markets.
