This product is a conical spring washer that complies with the DIN6796 and is made of SS304. It comes in specifications ranging from M3-M30 and is specifically designed for bolted connection structures. It features excellent elasticity, corrosion resistance, and fatigue resistance. It can effectively prevent loosening of fasteners caused by vibration, thermal expansion and contraction, and load changes through continuous elastic preload. It can be used in combination or in layers to meet different preload requirements. The installation is simple and the reliability is high. It is widely used in various mechanical, steel structure and equipment assembly scenarios where there are strict requirements for anti-loosening, vibration resistance and corrosion resistance.

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 producing Hex Titanium Nut, with specifications ranging from M1.6-M20. It is made of high-quality titanium alloy and industrial pure titanium precision machining. The product is produced according to the German standard DIN934, with a regular hexagonal shape and high thread accuracy, suitable for various fields.

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.

GB5787 10.9 grade hexagonal flange bolts (colored zinc M5-M12) are made of alloy steel and possess high strength and excellent vibration resistance. The environmentally friendly colored zinc coating has passed a 240-480-hour salt spray test, and also has both anti-corrosion and decorative functions. The integrated flange design can increase the supporting area and enhance the anti-loosening capability, and is suitable for connection scenarios in automobiles, construction machinery, outdoor facilities, etc. where high strength and corrosion resistance are required.

65MnSpring-Type Straight Pins ( GB/T 879.4) is manufactured from 65 manganese spring steel and undergoes heat treatment. It features high elasticity and fatigue resistance, and achieves a reliable connection through radial tension after installation, effectively resisting vibration and impact. The surface is blackened for basic rust prevention. The specifications range from 1mm to 20mm in diameter. It is widely used for shaft hole fixation and hinge connections in mechanical transmission, automotive components, mold positioning and other scenarios.
