Standard:SAE
Description:
The SAE 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 SAE 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 SAE 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.
