Professional Applications & Engineering Value

These SAE flat washers provide critical engineering solutions where corrosion resistance and dimensional precision are paramount. The black corrosion-resistant-coated steel construction specifically addresses oxidation and chemical degradation in industrial environments, extending maintenance intervals for machinery, electrical enclosures, and outdoor equipment. Manufactured to ASME B18.21.1 standards, these inch-system washers deliver reliable load distribution for No. 6 fasteners, preventing loosening from vibration and protecting sensitive surfaces from galling. The combination of controlled thickness (0.036-0.065") and standardized flat washer geometry ensures consistent clamping force in automotive assemblies, construction frameworks, and manufacturing equipment where industrial durability is non-negotiable.

Specification Summary & Compliance

This SAE flat washer maintains precise dimensional tolerances with 0.156" inner diameter and 0.375" outer diameter specifically engineered for No. 6 screw applications.
