Professional Applications & Engineering Value

This zinc-plated steel flat washer delivers critical engineering solutions for industrial applications where corrosion resistance and load distribution are paramount. The substantial 3" outer diameter creates an expanded bearing surface that effectively distributes clamping force, preventing surface damage and maintaining joint integrity in heavy machinery, structural steel connections, and equipment assembly. The zinc plating provides sacrificial protection against rust and environmental degradation, making these industrial washers ideal for outdoor applications, manufacturing facilities, and marine-adjacent environments. Engineered specifically for 1/4" screw size fasteners, these heavy-duty washers ensure reliable performance in vibration-prone applications while maintaining dimensional stability under sustained pressure.

Specification Summary & Compliance

This flat washer features inch system dimensions with 3" outer diameter, 0.281" inner diameter, and thickness ranging from 0.051" to 0.080". Manufactured from zinc-plated steel for consistent performance, the product maintains dimensional accuracy suitable for standard industrial applications. The washer is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and unrestricted use across global markets.
