Fractional Sizes of USS Washers with Clear Zinc Cr3 Plating
Low Carbon USS Flat Washers with Clear Zinc Cr3 Plating
Low carbon USS (United States Standard) flat washers are essential fastening components designed to evenly distribute the load from bolts, nuts, and screws across a wider surface area. This load distribution helps prevent surface damage, reduces fastener pull-through, and improves overall joint stability. Manufactured from low-carbon steel and finished with Clear Zinc Cr3 plating, these washers provide a dependable, cost-effective solution for both indoor and light outdoor applications.
What Are Low Carbon USS Flat Washers?
USS Standard Dimensions
Low carbon USS flat washers are produced to USS dimensional standards, which feature a larger outside diameter than SAE washers. This increased bearing surface makes them ideal for applications involving softer materials, oversized holes, or structural connections that require improved load spread.
Low Carbon Steel Construction
Made from mild, low-carbon steel, these washers offer excellent flexibility and toughness. Their malleability allows them to conform slightly under load, helping protect mating surfaces while maintaining consistent clamping force. This makes them a practical choice for general-purpose fastening across multiple industries.
Fractional Sizes for Broad Compatibility
Common Fractional Size Range
Low carbon USS flat washers are available in a wide range of fractional sizes, including 1/4", 3/8", 1/2", 5/8", 3/4", and 1". These sizes are designed to match standard bolt and nut dimensions, ensuring proper fit and reliable performance in a variety of fastening systems.
Consistent Load Distribution
The larger USS profile helps evenly spread fastener pressure, reducing stress concentrations and extending the service life of both the fastener and the joined materials.
Clear Zinc Cr3 Plating Benefits
Corrosion Resistance and Appearance
Clear Zinc Cr3 (trivalent chromium) plating provides a protective barrier against rust and oxidation while offering a bright, clean finish. This RoHS-compliant coating is an environmentally friendly alternative to Cr6 plating and is well-suited for environments with light moisture exposure.
Extended Service Life
The zinc coating helps prolong washer life in automotive, construction, and industrial applications where mild corrosion resistance is required.
Common Applications
Low carbon USS flat washers with Clear Zinc Cr3 plating are widely used in automotive assemblies, construction projects, manufacturing equipment, and general industrial maintenance.
With reliable load distribution, corrosion protection, and cost-effective performance, low carbon USS flat washers with Clear Zinc Cr3 plating are a smart choice for durable, long-lasting fastening solutions.
