Professional Applications & Engineering Value

This Grade 8 flat washer delivers critical engineering solutions where standard washers fail. The zinc yellow-chromate plated steel construction provides a robust barrier against rust and chemical exposure, extending service life in manufacturing plants, construction sites, and automotive assemblies. With Rockwell C43 hardness and precise dimensional tolerances, it maintains clamping force under extreme vibration and thermal cycling – preventing joint failure in heavy equipment, structural steel connections, and machinery foundations. The 7/16" sizing and inch system compatibility make it ideal for North American industrial standards, while the corrosion-resistant finish ensures performance in humid or corrosive environments without galling or seizing.

Specification Summary & Compliance

Manufactured to exact inch system dimensions: 0.469" ID × 0.922" OD with thickness ranging 0.110-0.126". Meets Grade 8 fastener strength requirements with Rockwell C43 hardness certification. Fully compliant with RoHS 3 (2015/863/EU) under exemption 6(a) for lead in steel alloys and REACH (EC 1907/2006) regulations as of January 2023. Designed for use with 7/16" screws in industrial and construction applications requiring high-strength, corrosion-resistant flat washers.
