Standard:DIN6916
Description:
The DIN 6916 washer, also known as a flat steel washer, is a type of washer that conforms to the standards set by the Deutsches Institut für Normung (DIN). It is commonly used in construction, machinery, and structural applications.
Here are some key details about the DIN 6916 washer with a Dacromet finish:
1.Material: The DIN 6916 washer is typically made from steel. When it has a Dacromet finish, a protective coating called Dacromet is applied to the washer's surface.
2.Size: The DIN 6916 washer is available in various sizes, ranging from M12 to M36. The size corresponds to the nominal diameter of the washer, matching the size of the bolt it is compatible with. For example, an M12 washer is designed for use with an M12 bolt.
3.Dacromet Finish: Dacromet is a corrosion-resistant coating that provides excellent protection against rust and other environmental factors. It is a thin, metallic coating that offers high durability and resistance to chemicals, moisture, and salt spray. Dacromet coatings are often silver or gray in color.
4.Shape: The DIN 6916 washer is a flat, circular washer with a central hole. It is typically larger in outer diameter compared to regular flat washers, providing a larger load-bearing surface.
5.Function: The primary function of the DIN 6916 washer is to distribute the load and prevent damage to the surface of the material being fastened. It helps to evenly distribute the pressure exerted by the bolt or nut and provides additional support.
6.Application: DIN 6916 washers with a Dacromet finish are commonly used in applications where corrosion resistance and durability are required. They are suitable for heavy-duty applications such as structural steelwork, steel construction, bridge building, and other applications involving high loads and critical connections.
