Description:
The USS washer, also known as a hardened steel washer, is a type of washer commonly used in the United States. It conforms to the USS (United States Standard) sizing system.
The USS washer is made from hardened steel, which provides enhanced strength and durability. It is available in various sizes ranging from 1/4" to 3" in diameter. The size is specified in inches and refers to the nominal diameter of the fastener it is designed to be used with.
In terms of surface finishes, USS washers can be found with a black oxide coating. Black oxide is a conversion coating that provides several benefits, including improved corrosion resistance and enhanced appearance. The black oxide coating forms a thin layer on the surface of the washer, providing a protective barrier against rust and other forms of corrosion.
The black oxide finish also gives the washer a black color, which can be aesthetically appealing and useful for certain applications.
