Professional Applications & Engineering Value
This zinc-plated steel flat washer delivers critical engineering solutions where corrosion resistance and load distribution are paramount. The zinc plating creates a protective barrier against oxidation, making it ideal for outdoor equipment, automotive assemblies, and marine applications where moisture exposure is frequent. With its 2" outer diameter, it effectively spreads clamping force over a wider area, preventing joint loosening and surface deformation in structural connections using 7/16" screws. The precise 0.469" inner diameter ensures snug fitment without binding, reducing installation time and improving assembly reliability in manufacturing lines, construction projects, and machinery maintenance. Its inch-system compatibility makes it a versatile choice for North American industrial standards.
Specification Summary & Compliance
Manufactured to standard inch-system dimensions with inner diameter of 0.469", outer diameter of 2", and thickness ranging 0.051-0.080" for consistent performance. This flat washer is engineered for use with 7/16" screws and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring restriction of hazardous substances while maintaining industrial reliability.
