Fanyi external hexagon bolts are surface treated with Dacromet. Dacromet is the transliteration of DACROMET in English, also known as Dacromet or Dacromet Rust. It is a new type of metal surface anti-corrosion coating that uses metal aluminum, zinc and chromic acid as the main coating materials.
The base materials using Dacromet are mainly steel and non-ferrous metals. After the coating liquid reacts with the metal base, a silver-gray anti-corrosion film is formed on its surface, isolating the base from the air and protecting the workpiece.
Dacromet is widely used in various industries, such as fasteners, construction, small hardware, road engineering and petrochemicals.
