Standard:DIN6916
Description:
The DIN 6916 washer, also known as a flat steel washer, is a specific type of washer that conforms to the standards set by the Deutsches Institut für Normung (DIN), which is the German Institute for Standardization. It is commonly used in construction, machinery, and structural applications.
Here are some key details about the DIN 6916 washer:
1.Material: The DIN 6916 washer is typically made from steel and may undergo a black oxide treatment for corrosion resistance and a black finish. The black oxide coating provides a protective layer against rust and enhances the washer's durability.
2.Size: The DIN 6916 washer is available in various sizes, ranging from M12 to M36. The size refers to the nominal diameter of the washer, which corresponds to the size of the bolt it is compatible with. For example, an M12 washer is designed to be used with an M12 bolt.
3.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.
4.Function: The main purpose 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.
5.Application: Due to their larger size and load-bearing capabilities, DIN 6916 washers are commonly used in heavy-duty applications where high-strength connections are required. They can be used in structural steelwork, steel construction, bridge building, and other applications that involve high loads and critical connections.
