Product Description



      The DIN 6340 washer, also known as a structural steel washer, is a type of washer that conforms to the DIN 6340 standard. It is commonly used in construction, engineering, and industrial applications where high load-bearing capacity and durability are required.

      The M6-M30 size range indicates that these washers are suitable for use with bolts or threaded fasteners ranging from M6 to M30 in diameter.

      In addition to the black oxide finish mentioned earlier, DIN 6340 washers are also available with other surface finishes such as zinc plating or hot-dip galvanizing (HDG).

      Zinc plating involves applying a protective layer of zinc to the surface of the washer. This coating provides corrosion resistance, helping to prevent rust and extending the lifespan of the washer.

      Hot-dip galvanizing (HDG) is a process where the washer is dipped into a bath of molten zinc. This results in a thicker layer of zinc coating compared to zinc plating, providing enhanced corrosion protection. HDG is particularly suitable for applications where the washer will be exposed to harsh environments or corrosive substances.

      Both zinc-plated and HDG DIN 6340 washers offer improved corrosion resistance compared to plain steel washers, making them suitable for outdoor or high-moisture environments.

      The choice between zinc plating and HDG depends on the specific requirements of the application, such as the level of corrosion resistance needed and the environmental conditions the washer will be exposed to.
