Professional Applications & Engineering Value
These Grade 8 SAE flat washers deliver exceptional engineering value in demanding industrial environments where corrosion resistance and structural integrity are paramount. The zinc yellow-chromate plated steel construction provides superior protection against oxidation and chemical exposure, while the Rockwell C38 hardness ensures the washer maintains its shape under extreme pressure. Ideal for heavy machinery, construction equipment, and automotive assemblies, these 3/8" washers prevent bolt loosening and distribute load evenly across surfaces. The ASME B18.21.1 compliance guarantees precise dimensional tolerances for consistent performance in critical fastening applications, making them essential components for engineers requiring reliable, long-lasting solutions.
Specification Summary & Compliance
Manufactured to exact ASME B18.21.1 standards with precise inch system dimensions (ID: 0.406", OD: 0.812", Thickness: 0.051-0.080"). These Grade 8 flat washers feature Rockwell C38 hardness and are constructed from zinc yellow-chromate plated steel for optimal performance. Fully compliant with REACH regulations (EC 1907/2006) and suitable for 3/8" screw applications requiring heavy-duty fastening solutions in industrial settings.
