DIN7984 12.9 grade Hexagon Socket Head Cap Screws with Low Head with Reduced Loadability, made of high-strength alloy steel and treated with blackening process, cover specifications from M3 to M22. They are low-load type short-head hexagonal bolts with lower head height, suitable for installation scenarios with limited space. They combine high strength with a compact structure, ensuring stable and reliable assembly.

Conforming to the ISO 15481-1999 standard, the cross-slot round-head (flat-head) self-tapping screws integrate the functions of drilling, self-tapping and locking. They do not require pre-drilling or nuts. The round head distributes pressure evenly and has a neat appearance. The cross-slot is compatible with manual/electric tools, and the torque transmission is stable without slippage. The drill tail can directly cut thin metals and non-metallic materials. The self-tapping threads have a tight bite and a secure connection. Installation is efficient and fast, and they are widely used in scenarios such as sheet metal, color steel, curtain walls, and home appliances. The specifications cover ST2.9 to ST6.3, and the materials are compatible with carbon steel and stainless steel, with surface treatments such as galvanization. This ensures both strength and rust resistance.

Jinghong Manufacturer specializes in providing Stainless Steel Thread Inserts, which are precision-wound from high-grade stainless steel wire. These inserts are designed to create high-strength standard internal threads in low-strength materials such as aluminum alloy and wood, and can also repair damaged threaded holes. With excellent wear resistance, corrosion resistance, shock resistance, and anti-loosening properties, they are an ideal choice for enhancing the reliability of threaded connections.

Jinghong Factory specializes in producing ISO 10642 Hexagon Socket Head Screws, which are made of high-quality carbon steel and designed with hexagonal. After installation, the screw head can be embedded to achieve a flat and non protruding invisible connection. We offer various strength grades such as 8.8, 10.9, 12.9, etc. The surface can be galvanized, blackened, or treated with natural color. After installation, it can be flush with the workpiece surface, which is both beautiful and can avoid interference, suitable for various fields.

Jinghong Factory specializes in producing Double Cap Rivets, using different high-quality materials and various surface treatments to choose from. The product features a chamfered head design, which is aesthetically pleasing and not harmful to the hands. It is driven by an inner hexagonal angle and has a strong locking force. The lock structure is suitable for various scenarios and supports non-standard customization.

The Knurled Thumb Screws produced by Jinghong Fasteners are made of Gr4.8 carbon steel and comply with the GB834 standard for tool-free hand tightening connection components. They are specially designed for frequent disassembly and manual adjustment scenarios and are commonly used standard fasteners in instrument, equipment, and assembly applications.
