Professional Applications & Engineering Value
This zinc-plated steel flat washer delivers exceptional engineering value in industrial fastening systems where corrosion protection and reliable load distribution are critical. The Grade 5 steel core provides mechanical strength to withstand high-stress conditions in machinery assembly, structural frameworks, and heavy equipment manufacturing. The zinc plating creates a protective barrier against moisture and chemical exposure, significantly extending component lifespan while maintaining dimensional stability. Engineered to ASME B18.21.1 standards, these 3/8" flat washers ensure precise fit and consistent performance in vibration-prone applications, preventing joint failure and reducing maintenance frequency across automotive, construction, and manufacturing sectors.
Specification Summary & Compliance
Manufactured to exact ASME B18.21.1 specifications with dimensional precision including 0.406" inner diameter, 1.25" outer diameter, and thickness range of 0.090-0.112". The Grade 5 steel construction meets industrial strength requirements while the zinc-plated finish provides corrosion protection. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures safe, sustainable use across global markets.
