Zinc Plated Hex Bolt
Zinc coating is a bolt process that is widely used now. It can not only improve the service life of hex bolts, but also make the hex bolts more beautiful. Jinrui can provide you with two kinds of galvanizing commonly used for hexagon bolts, One is electro-galvanized. After electro-galvanizing, if the hexagonal bolt encounters humid air, the zinc film on the surface of the bolt can isolate the air from the bolt base, so that the bolt wil not be easily corroded.

What is a Zinc Plated Hex Bolt?
First and foremost, let's explain what Zinc Plated Hex Bolt is. It is a type of fastener that is shaped like a hexagon with a threaded shaft. The shaft can be threaded partially or fully, depending on the application. Zinc Plated implies that this bolt has a zinc coating for protection against corrosion. This electroplated zinc layer provides a sacrificial barrier that prevents rusting and oxidation of the underlying metal.

Zinc coating is a bolt process that is widely used now. It can not only improve the service life of hex bolts, but also make the hex bolts more beautiful. Jinrui can provide you with two kinds of galvanizing commonly used for hexagon bolts, One is electro-galvanized. After electro-galvanizing, if the hexagonal bolt encounters humid air, the zinc film on the surface of the bolt can isolate the air from the bolt base, so that the bolt wil not be easily corroded. The zinc plated hex bolts are very clean and beautiful, and can be used in some dust-free workshops without oil or other pollution. It is also possible to change the color of electro-galvanizing according to requirements. There are zinc layers of different colors such as white zinc, blue-white zinc, colored zinc or black, which can play a very good decorative role in special environments. Zinc plated hexagon bolts are widely used, covering basically all industries.
Hot-dip galvanized is also a protective coating for hex cap screws. Its anti-corrosion performance is better than zinc electronic coating. The surface will be covered with a protective film with a thickness more than 45 microns, so the anti-corrosion performance of H.D.G hex bolts is good. The hot-dip galvanized bolts are mainly used in industries such as wind power facilities, photovoltaic base stations and national grid structures.
The two galvanizing processes have their own characteristics. Since the thickness of hot-dip galvanizing reaches more than 45 microns, it has a great influence on the thread. Generally, the specifications above M8 are suitable for hot-dip galvanizing treatment, while zinc coating does not have this limit. When H.D.G hex bolts assembling, over-size hot-dip galvanized nuts are required.
