Introduction
The hex nut is one of the most common fasteners because it is simple and powerful. Our Black Zinc Hex Nut is made of galvanized carbon steel. Carbon steel is very tough, but it is not resistant to corrosion. Because it is easier to process and does not break as easily as stainless steel, it is still very popular. So black zinc is galvanized on it to realize metal anti-oxidation. In this way, the product is black and shiny and has excellent corrosion resistance. It is mainly used in the protection of steel parts. Besides, the price is also low.

Our Black Zinc Hex Nut is hard, stable, and can be used for a long time. The surface is carefully polished, so the color of the product is uniform and the surface is smooth. Years of experience in design, production, and sales make us more professional. It can be used in construction, new energy, petrochemical industry, communications, light industry, and so on. If you have any questions, please contact us. We can also choose different sizes and shapes according to your actual needs.
