Surface Treatment
BLACK
☆ Black is a common method for metal heat treatment. The principle is to make an oxide film on the metal surface to isolate the air and achieve rust prevention.

ZINC
☆ Electro-galvanizing is a traditional metal coating treatment technology that provides basic corrosion resistance to metal surfaces. The main advantages are good solderability and suitable contact resistance. Due to its good lubrication properties, cadmium plating is commonly used in aviation, aerospace, marine, and radio and electronic products. The plating layer protects the steel substrate from both mechanical and chemical protection, so its corrosion resistance is much better than zinc plating.
HDG
☆ The main advantages are good solderability and suitable contact resistance. Due to its good lubrication properties, cadmium plating is commonly used in aviation, aerospace, marine, and radio and electronic products. The plating layer protects the steel substrate from both mechanical and chemical protection, so its corrosion resistance is much better than zinc plating. Hot-dip zinc has good corrosion resistance, sacrificial protection for steel substrates, high weather resistance, and resistance to salt water erosion. It is suitable for chemical plants, refineries and coastal and offshore operating platforms.
Frequently Asked Questions
What standards do these hexagon bolts and nuts conform to?
Our DIN934 hexagon bolts and nuts comply with major international standards including GB, DIN, ISO, and JIS. We also supply non-standard sizes customized to customer requirements.
What materials are available for the hex head fasteners?
We offer a wide range of materials to meet different applications, including Carbon Steel, Stainless Steel (such as SS304 and SS316), Brass, and Alloy Steel.
What size range and strength grades do you offer?
We supply sizes ranging from M3 to M100 (or 1/4" to 4" as well as non-standard sizes). The available grades include 4.8, 6.8, 8.8, 10.9, 12.9, ASTM A194 Grades 2, 2H, 4, 7, 7M, 8, 8M, and ASTM A563 Grades A, C, DH, DH3.
What are the benefits of Hot-Dip Galvanizing (HDG) treatment?
Hot-dip zinc (HDG) offers superior corrosion resistance, sacrificial protection for steel substrates, high weather resistance, and strong resistance to salt water erosion. It is highly recommended for chemical plants, refineries, and coastal or offshore operating platforms.
How does the Zinc Plating compare to Cadmium Plating?
Electro-galvanizing (Zinc Plating) provides basic corrosion resistance, good solderability, and suitable contact resistance. Cadmium plating, on the other hand, offers excellent lubrication properties and superior mechanical/chemical protection, making its corrosion resistance much better than standard zinc plating. It is commonly used in aviation, marine, and electronic products.
What packaging options are provided for shipping?
Our standard packaging includes boxes, cartons, or plastic bags, which are then securely placed on pallets. Custom packaging configurations are also available according to customer demands.
