Professional Applications & Engineering Value

These SAE flat washers manufactured from zinc-plated steel provide critical engineering solutions for industrial assembly and maintenance operations. The 0.156" inner diameter precisely accommodates No. 6 screws, while the 0.375" outer diameter creates an optimal bearing surface to prevent fastener embedding and distribute clamping forces evenly. The zinc plating delivers essential corrosion resistance in environments where moisture, chemicals, or atmospheric exposure could compromise joint integrity. Engineered to ASME B18.21.1 standards, these flat washers ensure dimensional consistency and reliable performance in automotive, machinery, electrical enclosures, and general manufacturing applications where vibration resistance and long-term fastener security are paramount.

Specification Summary & Compliance

This SAE flat washer features precise dimensional specifications including 0.156" inner diameter, 0.375" outer diameter, and thickness ranging from 0.036" to 0.065". Manufactured in accordance with ASME B18.21.1 standards for dimensional accuracy and performance requirements. The product is fully compliant with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations concerning chemical substances, ensuring environmental responsibility and regulatory adherence for industrial applications.
