Standard:DIN6916
Description:
The DIN 6916 washer, also known as a hardened steel washer, is a type of washer that conforms to the German Industrial Standard (DIN) 6916 specification. It is commonly used in structural applications where high-strength connections are required.
Here are some key features of the DIN 6916 washer:
1.Material: The washer is made from hardened steel, which provides excellent strength and durability.
2.Sizes: The DIN 6916 washer is available in a range of sizes from M12 to M36. The "M" stands for metric, and the number refers to the thread diameter in millimeters.
3.Black Oxide Finish: The washer typically has a black oxide coating on its surface. This finish provides corrosion resistance and also gives the washer a black appearance.
4.Shape: The washer has a circular shape with a hole in the center. The outer diameter is larger than the inner diameter, creating a flat surface that distributes the load evenly when tightened.
5.Hardness: DIN 6916 washers are hardened to achieve high strength and resistance to deformation under heavy loads.
These washers are commonly used in construction, machinery, and other applications where secure and reliable fastenings are required. They are typically used in conjunction with high-strength bolts or nuts to create a strong and stable connection.
