Professional Applications & Engineering Value

These galvanized steel flat washers provide critical engineering solutions where corrosion resistance and dimensional precision are paramount. The zinc coating creates a protective barrier against oxidation, making these SAE washers ideal for outdoor equipment, automotive assemblies, and industrial machinery exposed to moisture or chemicals. The specific 0.156" inner diameter ensures perfect alignment with No. 6 screw sizes, eliminating play and reducing installation time. Manufactured to ASME B18.21.1 specifications, these flat washers deliver consistent performance in high-vibration environments, preventing loosening and maintaining clamping force in critical joints. The 0.375" outer diameter optimally distributes pressure across softer materials, preventing surface indentation and material failure.

Specification Summary & Compliance

This SAE flat washer maintains precise dimensional tolerances per ASME B18.21.1 standards with 0.156" inner diameter, 0.375" outer diameter, and thickness ranging 0.036-0.065". Manufactured from galvanized steel for enhanced durability, the product fully complies with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations regarding chemical safety.
