Standard:DIN6340
Description:
DIN 6340 does not specify a specific type of washer or chamfered washer. DIN 6340 is a standard that specifies dimensions and technical requirements for round washers made of steel or stainless steel, with a thickness of 1.6 mm to 36 mm.
However, if you are looking for hot-dip galvanized washers in the specified size range (M6 to M30) with an HDG finish, you can generally find them from various manufacturers and suppliers. Hot-dip galvanizing is a process where the washers are immersed in molten zinc, creating a thick, protective coating that provides excellent corrosion resistance.
When selecting hot-dip galvanized washers, it is important to ensure that they meet the required specifications and standards for your application. You can consult the relevant industry standards, such as ISO, EN, or national standards, to determine the specific requirements for the washers you need.
