Professional Applications & Engineering Value
These Grade 8 zinc-plated steel flat washers deliver critical engineering solutions where vibration resistance and load distribution are paramount. The zinc-plated steel construction provides essential corrosion protection in industrial environments exposed to moisture, chemicals, and temperature variations. With Rockwell C38 hardness and Grade 8 strength classification, these 3/4" washers maintain integrity under extreme pressure in heavy machinery, structural steel connections, and automotive assemblies. The precise 0.812" ID ensures secure fastener seating while the 2" OD maximizes surface contact area, preventing joint loosening and material deformation in critical industrial applications requiring reliable fastener performance.
Specification Summary & Compliance
Manufactured to ASME B18.21.1 standards with inch system dimensions: 0.812" inner diameter, 2" outer diameter, and thickness range of 0.090-0.112". The Grade 8 classification ensures high tensile strength while Rockwell C38 hardness provides consistent mechanical properties. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms environmental safety and restricted substance adherence for global industrial distribution and use.
