USA SAE Flat Washer Thru Hardened with Yellow Zinc Cr6 Plating
USA SAE Thru Hardened Flat Washers with Yellow Zinc Cr6 Plating
When structural strength and corrosion resistance are equally important, USA-made SAE thru hardened flat washers with Yellow Zinc Cr6 plating deliver dependable, industrial-grade performance. Designed for high-load, high-torque applications, these washers combine heat-treated durability with enhanced environmental protection—making them a trusted choice across automotive, industrial, and heavy equipment sectors.
Engineered for Strength and Load Retention
Thru Hardened Medium Carbon Steel
Manufactured from medium carbon steel and produced in accordance with SAE J995 specifications, these flat washers undergo a full thru hardening heat treatment process. Unlike surface-hardened washers, thru hardened designs ensure uniform hardness throughout the entire washer body. This significantly improves resistance to crushing, deformation, embedding, and galling under extreme clamp loads.
Consistent Clamp Force Performance
These washers are engineered to maintain bolt preload and joint integrity, even in vibration-heavy environments. They are ideal for assemblies that require reliable torque retention and long-term mechanical stability.
Yellow Zinc Cr6 Plating for Superior Corrosion Protection
Durable Gold-Tinted Finish
The Yellow Zinc Chromate (Cr6) coating provides enhanced corrosion resistance while delivering a distinctive gold appearance. This finish improves resistance to moisture, oxidation, and industrial wear, making it suitable for outdoor and exposed applications.
Enhanced Wear and Visibility
The plated surface not only protects against environmental degradation but also improves fastener visibility and identification in complex assemblies.
Precision SAE Dimensions and USA Quality
These washers are manufactured to SAE dimensional standards, featuring a smaller outer diameter than USS washers for tighter, precision-fit installations. Tight ID and OD tolerances ensure accurate bolt alignment and consistent load distribution.
Common applications include automotive and truck manufacturing, agricultural equipment, machinery assembly, structural hardware, and industrial maintenance. For high-performance fastening that demands strength, durability, and corrosion resistance, USA SAE thru hardened flat washers with Yellow Zinc Cr6 plating provide long-lasting, professional-grade reliability.
