Product Description



      The DIN 6340 standard refers to washers, specifically heavy washers, used in mechanical and structural applications. These washers are designed to distribute the load of a threaded fastener, such as a bolt or a screw, over a larger surface area. The specific parameters you mentioned, M6-M30, refer to the size range of the washers, indicating that they are available in metric sizes ranging from M6 to M30.

      The "Zinc plated" and "HDG" abbreviations refer to different types of surface coatings applied to the washers to provide corrosion resistance. "Zinc plated" means that the washers have been coated with a layer of zinc, which helps protect the underlying metal from rust and corrosion. This coating is typically applied through a process called electroplating.

      On the other hand, "HDG" stands for "Hot-Dip Galvanized." This is a more robust and durable coating compared to zinc plating. In the hot-dip galvanizing process, the washers are immersed in a bath of molten zinc, which forms a thick layer of zinc coating on the surface. Hot-dip galvanized coatings provide excellent corrosion resistance and are commonly used in outdoor and harsh environments.

      In summary, DIN 6340 washers are heavy-duty washers available in metric sizes from M6 to M30. They can be found with either a zinc-plated or hot-dip galvanized coating, depending on the desired level of corrosion resistance needed for the application.
