Grade 8.8 hot dip galvanized bolts are high-strength bolts. Compared with ordinary bolts, the tensile strength of high-strength bolts will be improved.
Hot dip galvanized hexagon bolt is used to make molten metal react with iron matrix to produce alloy layer, so as to combine the matrix and coating.
Hot galvanizing refers to pickling of iron and steel parts. In order to remove iron oxide on the surface of iron and steel parts, after pickling, they are cleaned in ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank, and then sent to the hot dip tank.
The hot-dip galvanized hexagon bolt has the advantages of even coating, strong adhesion, waterproof and long service life.
