Description:
The USS washer, is a type of fastener commonly
used in various industrial applications. It is designed to
distribute the load of a threaded fastener, such as a bolt or a
screw, over a larger surface area to prevent damage to the material
being fastened or to provide additional support.
The USS washer is available in different
materials and finishes to suit specific requirements. Here are some
common options:
1.Plain: Plain washers are typically made of
low-carbon steel or stainless steel and have a basic, untreated
surface. They provide standard protection against corrosion and are
suitable for general-purpose applications.
2.Dacromet: Dacromet is a coating that
provides excellent corrosion resistance. Dacromet-coated washers
are often used in environments with high humidity, exposure to
saltwater, or other corrosive substances.
3.Black Oxide: Black oxide is a conversion
coating that offers moderate corrosion resistance and provides a
dark black appearance. Black oxide-coated washers are commonly used
in applications where aesthetics and mild corrosion protection are
desired.
4.Zinc Plated: Zinc plating is a popular
surface treatment that provides good corrosion resistance.
Zinc-plated washers have a bright, silver-colored finish and are
commonly used in various applications, including automotive,
construction, and general machinery.
5.HDG (Hot-Dip Galvanized): HDG refers to the
process of coating the washer with a layer of zinc by immersing it
in molten zinc. This coating provides excellent corrosion
protection, making HDG washers suitable for outdoor or marine
applications where they may be exposed to harsh environments.
It's important to note that "non-standard"
refers to their customization options, such as size, thickness, and
material, which can be tailored to specific requirements.
When selecting USS washers or any fasteners,
it's crucial to consider the specific application, load
requirements, and environmental factors to ensure optimal performance and durability. Consulting with us can be helpful in
choosing the right type of washer for your needs.
