Professional Applications & Engineering Value
Engineered for demanding industrial environments, this Grade 8 USS flat washer delivers critical performance where vibration resistance and load distribution are paramount. The black corrosion-resistant coated steel construction provides essential protection against environmental degradation, significantly extending service life in outdoor applications, marine environments, and chemical processing facilities. With its precise 7/16" inner diameter and 1.25" outer diameter, this washer effectively distributes clamping force across a wider surface area, preventing joint loosening and material deformation in heavy machinery, structural steel connections, and high-torque applications. The Rockwell C38 hardness ensures maintained dimensional stability under extreme pressure, making it ideal for critical assemblies where fastener integrity cannot be compromised.
Specification Summary & Compliance
This precision USS flat washer features dimensional specifications of 0.5" ID, 1.25" OD, and 0.110-0.126" thickness, manufactured to ASME B18.21.1 standards for consistent quality and performance. The washer maintains Grade 8 strength classification with Rockwell C38 hardness for superior mechanical properties. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures responsible manufacturing practices and workplace safety standards.
