Low Carbon USS Flat Washers with Yellow Zinc Cr6 Plating
Low carbon USS (United States Standard) flat washers are essential fastening components designed to evenly distribute load across a wider surface area. By spreading clamping force from bolts, nuts, and screws, these washers help prevent surface damage, reduce fastener pull-through, and improve overall joint stability. Manufactured from low-carbon steel and finished with Yellow Zinc Cr6 plating, they deliver a reliable balance of strength, flexibility, and corrosion resistance for demanding applications.
What Are Low Carbon USS Flat Washers?
USS Standard Design and Function
Low carbon USS flat washers are produced to USS dimensional specifications, which feature a larger outside diameter than SAE washers. This broader profile provides enhanced load distribution, making them especially effective when used with softer materials, oversized holes, or structural connections where added surface coverage is required.
Low Carbon Steel Construction
Made from mild, low-carbon steel, these washers offer excellent malleability and toughness. Their flexibility allows them to conform slightly under load, protecting mating surfaces while maintaining consistent clamping force. This makes them a cost-effective and dependable choice for general-purpose and industrial fastening.
Fractional Sizes for Versatile Applications
Common Fractional Size Range
Low carbon USS flat washers are available in a wide selection of fractional sizes, including 1/4", 3/8", 1/2", 5/8", 3/4", and 1". These sizes align with standard bolt and nut dimensions, ensuring proper fit and reliable performance across a variety of fastening systems.
Improved Load Distribution
The oversized USS profile helps reduce stress concentrations, extending the service life of both fasteners and joined materials.
Yellow Zinc Cr6 Plating Benefits
Enhanced Corrosion Protection
Yellow Zinc Cr6 plating provides a durable protective layer that resists rust, oxidation, and moisture exposure. The distinctive yellow finish also makes these washers easy to identify in assemblies and inventory.
Durability in Harsh Environments
This plating is well-suited for applications exposed to weather, chemicals, and industrial conditions, making it ideal for both indoor and outdoor use.
Common Applications
Low carbon USS flat washers with Yellow Zinc Cr6 plating are widely used in automotive assemblies, construction projects, industrial equipment, and general maintenance applications where corrosion resistance and load distribution are critical.
With dependable performance, broad compatibility, and enhanced protection, low carbon USS flat washers with Yellow Zinc Cr6 plating provide a durable fastening solution built for long-lasting reliability.
