The Dacromet Hex Bolt refers to a hexagonal bolt that has been treated with the Dacromet process and is highly resistant to corrosion. The Dacromet process can resist the erosion of chloride ions, reform the defects of the traditional process of anti-corrosion, and put the anti-corrosion technology into a new stage. It can be said that it is a new process of epoch-making significance in the international surface treatment industry.
Dacromet hex bolt is more environmentally friendly than ordinary galvanized and mechanical galvanized, hot-dip galvanized surfaces. Hot-dip galvanizing and mechanical galvanizing are preferred if they refer only to functional aspects such as corrosion protection and oxidation. However, these two surface treatment methods make the bolt and nut difficult to fit (usually the nut needs to be reamed, so that the internal thread of the nut is not hot-dip galvanized), because the surface of the bolt is thickened.
