Product Description



      The DIN 6340 washer, also known as a structural steel washer, is a specific type of washer that conforms to the DIN 6340 standard. DIN stands for "Deutsches Institut für Normung," which translates to "German Institute for Standardization." The DIN 6340 standard specifies the dimensions, material, and other characteristics of structural steel washers.

      These washers are commonly used in construction, engineering, and industrial applications where high load-bearing capacity and durability are required. The M6-M30 refers to the range of metric sizes available for these washers, indicating that they are suitable for use with bolts or threaded fasteners ranging from M6 to M30 in diameter.

      The black oxide finish on these washers provides a layer of corrosion resistance and an attractive appearance. Black oxide is a conversion coating that forms a thin layer of black oxide on the surface of the washer, enhancing its durability and resistance to rust.

      Overall, DIN 6340 washers are designed to distribute the load of the fastener over a larger area, reducing the risk of damage to the connected components and improving the overall stability and reliability of the assembly.
