DIN6921 hot-dip galvanized flange bolts are usually made of carbon steel and the surface is hot-dip galvanized. Hot-dip galvanizing is an effective anti-corrosion method. By coating a layer of zinc on the surface of the bolt, it can effectively prevent the bolt from corrosion and extend its service life. It is used in machinery and equipment, automobile manufacturing, shipbuilding, water conservancy engineering and other industries.
