USA SAE Thru Hardened Flat Washers with Yellow Zinc Cr6 Plating – Industrial-Grade Strength Meets Superior Corrosion Protection

If your application demands both structural strength and enhanced corrosion resistance, USA-made SAE thru hardened flat washers with yellow zinc Cr6 plating are the ideal fastener solution. Engineered from medium carbon steel and heat-treated for consistent hardness, these washers are built to perform in high-load environments where reliability is critical.

The thru hardening process sets these washers apart. Unlike surface-only treatments, thru hardening ensures that the entire washer is heat-treated, offering resistance to deformation, galling, and crushing under heavy torque. Pair that with yellow zinc Cr6 plating, and you’ve got a washer that not only stands up to mechanical stress but also offers superior corrosion protection—ideal for outdoor, automotive, and industrial use.

Material & Finish:

  • Material: Medium carbon steel, SAE J995 compliant
