Description:
The USS Washer, also known as a Zinc Plated Washer, is a type of flat washer commonly used in general-purpose applications. It is designed to provide a smooth, even surface for distributing the load of a fastener, such as a bolt or nut, and to prevent damage to the connected materials.
The USS (United States Standard) Washer is specified by the American National Standards Institute (ANSI) and the American Society of Mechanical Engineers (ASME). This standard ensures that the washer meets specific requirements for its dimensions, material composition, and performance.
The Zinc Plated Washer refers to the surface treatment applied to the washer. Zinc plating provides a layer of corrosion resistance, which helps protect the washer from rust and other forms of degradation. This makes the washer suitable for use in both indoor and outdoor environments, especially in applications where exposure to moisture or other corrosive elements is a concern.
The size range of the USS Washer is specified in inches, ranging from 1/4" to 3" in diameter. The washer is compatible with fasteners in this size range, allowing it to be used in various general-purpose applications where different sizes of bolts or nuts are required.
In summary, the USS Washer/Zinc Plated Washer is a flat washer designed for general-purpose applications. It provides load distribution and corrosion resistance, and its size range makes it suitable for use with a wide range of fasteners in different applications.
