Product Description

Standard:USS

Description:

      USS (United States Standard) washers are commonly used in North America and are specified by the ASTM F436 standard. They are flat washers with a larger outer diameter compared to SAE (Society of Automotive Engineers) washers. The size range you mentioned, 1/4" to 3", refers to the nominal diameter of the bolt or screw they are designed to work with.

      When specified with a "Hot Dip Galvanized" (HDG) finish, USS washers have undergone a process called hot-dip galvanizing. Hot-dip galvanizing is a method of coating steel with a layer of zinc to provide corrosion protection. The washers are immersed in a bath of molten zinc, allowing the zinc to bond with the surface of the washers, forming a thick and durable coating.

      HDG-coated USS washers offer excellent corrosion resistance, making them suitable for outdoor or highly corrosive environments. The thick layer of zinc acts as a barrier, protecting the washers from rust and corrosion. Hot-dip galvanizing provides a long-lasting and robust finish, making it a popular choice for applications where corrosion resistance is critical, such as in construction, infrastructure, and marine projects.

      When selecting USS washers with an HDG finish, it's important to ensure that they comply with the required specifications and standards for your application. Consult the ASTM F436 standard to determine the specific requirements for the washers you need.
