China Fastener Nuts Manufacturers, Suppliers, Factory

Blue and white zinc hexagonal flange nuts (M3-M16) are made of carbon steel and undergo blue and white zinc electroplating treatment on the surface, providing excellent corrosion resistance and decorative appearance. The flange design increases the bearing area and has the function of a lock washer. They comply with DIN6923 standards and are suitable for fastening connections in automotive, mechanical, construction and other fields that have high requirements for corrosion resistance and aesthetics.

Jinghong manufacturer specializes in designing high-quality hex nuts for international projects and the Russian market, with German DIN 934, Russian ГОСТ 5915-70, and international ISO 4032 standards. Providing B-level accuracy, multiple performance levels, and anti-corrosion treatment, suitable for assembly of heavy machinery, steel structures, and high standard equipment.

The red copper welding nut stud uses high-purity copper material, with optimized welding technology for secure bonding to various metal substrates. Its natural oxide film provides corrosion resistance. Available in M3-M8 sizes with customizable lengths and tin/nickel plating, it maintains stable performance at 200°C, making it ideal for electrical grounding, new energy battery connections, refrigeration equipment, and other applications requiring high conductivity, heat dissipation, and structural strength.

DIN986 Prevailing Torque Type Hexagon Domed Cap Nuts with Nonmetallic Insert with top features a dome-shaped design, and an nylon ring is embedded inside. The friction force is generated through the elastic deformation of the nylon, achieving the self-locking and anti-loosening function. The surface is coated with white zinc, which has certain anti-corrosion capabilities and a neat and beautiful appearance. It is commonly used in mechanical equipment, automotive parts, and other occasions where anti-loosening and protection of the threaded end are required.

Carbon steel square welded nut, specially designed for thin-walled structures such as sheet metal and frames. The standard square shape is easy to locate, the large welding surface ensures firmness, and the internal thread provides a reliable connection. Electrogalvanizing for rust prevention is an economical and efficient solution to replace traditional spot welding bolts.

The DIN985 Nylon Insert Lock Nut (Grade 4, White Zinc Plated) is a high-strength fastener that utilizes nylon ring embedding technology to achieve effective anti-loosening. Combining Grade 4 material with white zinc plating, it offers excellent mechanical properties and corrosion resistance, making it suitable for high-vibration harsh environments. Jinghong Standard Parts ensures product consistency through precision manufacturing processes, enabling reliable applications in automotive, machinery, power equipment, and other fields.
