Hot Dip Galvanized(HDG) Socket Cup Head Bolt
Features and Applications of Hot Dip Galvanized(HDG) Socket Cup Head Bolt
The coating of hot-dip galvanized bolts is very thick, usually 30 to 60 microns, and the coating has a high corrosion resistance, suitable for long-term outdoor work in the rust prevention project, such as highway fences, power towers, construction, light industry, petrochemical, communications, new energy industry and large fasteners. In addition, older iron water pipes are also connected by hot-dip galvanized bolts.
