Professional Applications & Engineering Value

This Grade 8 flat washer delivers critical engineering solutions where vibration resistance and corrosion protection are paramount. The zinc yellow-chromate plated steel construction creates a robust barrier against oxidation and chemical exposure, significantly outperforming standard washers in demanding applications like heavy machinery, construction equipment, and automotive assemblies. With Rockwell C43 hardness and precise inch-system dimensions (0.531" ID x 1.062" OD), it prevents bolt loosening under dynamic loads while distributing pressure evenly across mating surfaces. The combination of high-strength materials and advanced surface treatment makes this industrial washer ideal for applications requiring long-term reliability in challenging environments where fastener failure is not an option.

Specification Summary & Compliance

Manufactured to exacting standards with dimensional precision including 0.531" inner diameter, 1.062" outer diameter, and controlled thickness between 0.190-0.208". This Grade 8 flat washer meets rigorous industry requirements for heavy-duty applications and complies with RoHS 3 (2015/863/EU) with exemption 6(a) for lead as an alloying element in steel, along with full REACH (EC 1907/2006) compliance as of January 17, 2023. The inch-system measurement ensures compatibility with standard North American fastener specifications.
