Product Description


      The EN 14399-6 washer, also known as a structural steel washer, is a type of washer that conforms to the EN 14399-6 standard. These washers are commonly used in structural steel connections and preloaded bolt assemblies.

      The M12-M36 size range indicates that these washers are suitable for use with bolts or threaded fasteners ranging from M12 to M36 in diameter.

      EN 14399-6 washers can be available with two common surface finish options: zinc plating and hot-dip galvanizing (HDG).

      Zinc plating involves applying a thin layer of zinc to the surface of the washer. This coating provides corrosion resistance, helping to prevent rust and extend the lifespan of the washer. Zinc-plated EN 14399-6 washers are suitable for applications where moderate corrosion resistance is required.

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

      The choice between zinc plating and HDG depends on the specific requirements of the application, including the level of corrosion resistance needed and the environmental conditions the washer will be exposed to. Both options offer improved corrosion resistance compared to plain steel washers, providing greater durability and longevity in structural steel connections.
