DIN6340 Washer/High Tensile Washer, M6-M30, Zinc plated/HDG

Standard:DIN6340

Description:

      DIN 6340 washers, also known as high tensile washers or structural washers, are commonly used in applications that require high strength and load-bearing capabilities. These washers conform to the DIN 6340 standard, which specifies the dimensions and material requirements for these washers.

      The size range of DIN 6340 washers is typically specified in metric measurements, such as M6 to M30. This indicates that DIN 6340 washers can accommodate metric fasteners with diameters ranging from M6 to M30.

      DIN 6340 washers are available with two common coating options: zinc plated and hot-dip galvanized (HDG).

      Zinc plated DIN 6340 washers have a thin layer of zinc electroplated onto the surface. The zinc coating provides a sacrificial layer that helps protect the washer from corrosion. Zinc plating offers moderate corrosion resistance and is commonly used in indoor or low-corrosion environments.

      HDG (hot-dip galvanized) DIN 6340 washers undergo a hot-dip galvanizing process, where they are immersed in a bath of molten zinc. This forms a thicker and more durable zinc coating compared to zinc plating. HDG provides enhanced corrosion resistance and is suitable for outdoor, high-moisture, or corrosive environments.

      When selecting between zinc plated and HDG DIN 6340 washers, consider the specific environmental conditions in which they will be used. If the application involves exposure to moisture, humidity, or corrosive substances, HDG DIN 6340 washers would provide better corrosion protection. For indoor or low-corrosion environments, zinc plated DIN 6340 washers may be sufficient.
