China Hex Nut Manufacturers, Suppliers, Factory

Jinghong manufacturer specializes in producing DIN439 hexagonal thin nuts, with specifications ranging from M2 to M64, produced according to the German standard DIN439, divided into two series: fine tooth and coarse tooth. The product is made of high-quality carbon steel cold heading forming, and the surface can be galvanized, blackened or treated with natural color. The thickness is only about half of the standard nut, suitable for situations with limited space or requiring anti loosening fit.

ISO7042 All-metal threaded locking thick nuts (M5-M36) adopt the threaded compression deformation technology to achieve non-nylon elastic locking. They have a wide temperature tolerance range, and the thickened design enhances the anti-detachment strength. The surface blue-white zinc coating provides long-term corrosion resistance. They are suitable for reliable anti-loosening connections in high-vibration, high-temperature and heavy-load scenarios such as heavy machinery, automobiles, and steel structures.

Jinghong Manufacturer specializes in providing GOST5919 Hex Slotted Thin Castle Nut, which is made of high-quality carbon steel or stainless steel. The unique slotted design at the top, combined with an open mouth pin, achieves mechanical double locking, completely preventing vibration loosening. Thin structure saves space and is widely used in various fields with strict safety requirements.

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.

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.
