Standard:DIN6340
Description:
The DIN 6340 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 DIN 6340 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 DIN 6340 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.
