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 0.531" inner diameter ensures precise fitment with 1/2" screw sizes, while the substantial 3" outer diameter provides exceptional surface coverage to prevent embedding and distribute clamping forces evenly. The zinc plating creates a protective barrier against oxidation and environmental degradation, making these industrial washers ideal for outdoor equipment, machinery assembly, and structural applications where moisture and chemical exposure are concerns. The controlled 0.051-0.080" thickness maintains consistent performance under vibration and dynamic loading conditions common in heavy-duty washers applications.

Specification Summary & Compliance

Manufactured to precise inch system dimensions with 0.531" ID and 3" OD with thickness tolerance of 0.051-0.080". This flat washer complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring safe usage across various industrial sectors. The zinc-plated steel construction provides reliable performance for 1/2" screw size applications requiring consistent dimensional accuracy and environmental compliance.
