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 (FAQ)
What standards do your hexagon bolts and nuts comply with?
Our hexagon bolts and nuts are manufactured in strict accordance with major international standards, including GB, DIN (such as DIN934), ISO, and JIS, ensuring global compatibility and high quality.
What materials are available for DIN934 hex nuts?
We offer a wide range of materials to meet different application needs, including Carbon steel, Stainless steel (SS304, SS316), Brass, and Alloy steel.
What size ranges do you provide for these fasteners?
Our standard sizes range from M3 to M100 metric, and 1/4″ to 4″ imperial sizes. We also support customized non-standard sizes based on customer drawings and specifications.
What is the difference between Zinc Plating and HDG (Hot-Dip Galvanizing)?
Electro-galvanizing (Zinc) provides good solderability, contact resistance, and a smooth finish. Hot-Dip Galvanizing (HDG) offers much thicker zinc protection, making it highly weather-resistant and ideal for harsh environments like marine, coastal, and chemical plant applications.
What strength grades do you offer for hex head bolts and nuts?
We supply multiple strength grades, including metric grades 4.8, 6.8, 8.8, 10.9, and 12.9, as well as ASTM A194 (Grades 2, 2H, 4, 7, 7M, 8, 8M) and ASTM A563 (Grades A, C, DH, DH3).
How are the bolts and nuts packaged for shipment?
Our standard packaging includes boxes, cartons, or plastic bags, which are then securely loaded onto pallets. We can also customize the packaging according to the specific requirements of our customers.
