China Fastener Nuts Manufacturers, Suppliers, Factory

Strictly manufactured to DIN 934, this PEEK hex nut is injection-molded from pure polyetheretherketone resin in a natural beige finish. It outperforms conventional metal nuts in heat resistance (continuous use at 260℃, short-term up to 310℃), chemical resistance against most acids, alkalis, and solvents, as well as electrical insulation and non-magnetic properties. With low water absorption, high dimensional stability, good mechanical strength, and wear resistance, it weighs only about one-fifth of steel nuts — making it an ideal metal replacement for demanding applications in semiconductor, medical, chemical, and electronic equipment.

Our factory specializes in producing Flat/Countersunk Head Rivet Nut, which includes two materials: stainless steel and carbon steel, with flat head and countersunk head types. The product is installed on thin plates, pipes and other workpieces through a riveting gun, forming reliable internal threads for subsequent screw connections. Widely used in various industries.

The stainless steel square wing nut is a hand-tightening fastener made of 304 or 316 stainless steel. The design with square wings on both sides enables it to be quickly tightened or disassembled without tools, significantly improving the operational efficiency in frequent assembly and disassembly scenarios. The square base effectively prevents the nut from rotating, ensuring a stable connection. The stainless steel material gives it excellent rust and corrosion resistance, allowing it to be used for a long time in humid, outdoor, and chemical environments. This product is widely applicable in manual quick-connecting scenarios for light to medium load fastening in mechanical equipment maintenance doors, pipeline valves, assembled furniture, and outdoor facilities.

Jinghong Factory specializes in producing brass hex nuts, made of brass with high thread accuracy and standard hexagonal edge dimensions. The surface of the product has a golden metallic luster. Brass nuts have good conductivity, corrosion resistance, and do not produce magnetism. The specifications range from M2 to M16, and both coarse and fine teeth can be produced. Regular sizes are readily available in stock, and non-standard customization is supported.

The DIN557 stainless steel square nuts are made of A2 or A4 stainless steel and possess excellent corrosion resistance. Their square structure is specifically designed for anti-turning and slot rail installation, enabling them to effectively fit into the T-shaped slots of industrial aluminum profiles or the edges of structures, preventing slippage during tightening. They are particularly suitable for frame assembly, welding structures, and single-side operation scenarios. The specifications range from M5 to M16. They are an efficient fastening solution for mechanical equipment, racks, and general industrial connections.

Our factory specializes in producing 304 stainless steel nylon hexagonal flange locking nuts, which are formed by SUS304 cold heading. The flange surface is integrated with the hexagon, and nylon anti loosening rings are pressed into the inside. After tightening the nut, the nylon ring is locked with the bolt thread, effectively preventing loosening and can be reused multiple times. Replacing flat pads with flange surfaces increases the contact area and disperses pressure.
