Professional Applications & Engineering Value

These black-oxide steel flat washers deliver critical engineering solutions where corrosion resistance and dimensional precision are paramount. The SAE flat washer design with specific No. 6 screw compatibility addresses common assembly challenges by preventing screw head embedment and distributing clamping forces evenly across surfaces. The black-oxide surface treatment creates a protective barrier against oxidation and environmental degradation, making these industrial washers ideal for automotive assemblies, machinery manufacturing, and outdoor equipment where moisture exposure is a concern. Manufactured to ASME B18.21.1 standards, these components ensure reliable performance in vibration-prone applications while maintaining consistent thickness tolerances for uniform pressure distribution across fastened joints.

Specification Summary & Compliance

This SAE flat washer features precise inch dimensions with 0.156" internal diameter, 0.375" outer diameter, and thickness ranging 0.036-0.065" for No. 6 screw applications. Manufactured in compliance with ASME B18.21.1 mechanical standards for flat washers, ensuring dimensional consistency and mechanical properties. The product meets RoHS 3 (2015/863/EU) compliance for hazardous substance restrictions and REACH (EC 1907/2006) regulations regarding chemical substances, confirming environmental responsibility and regulatory adherence for industrial distribution.
