M3 * 0.5 Thread Protect And Repair Stainless Steel Thread Inserts


Wire thread insert is a new type of internal threaded fastener, suitable for threaded connection. It is screwed into and fastened in the threaded hole of one of the connected parts to form a standard internal thread. The bolt (or screw) is then screwed into it. Also known as threaded wire sleeve, wire sleeve for short. It is a high-strength, high-precision, smooth surface of the cold-rolled stainless steel wire precision diamond machining made of a spring-like member concentric with and external thread, used to enhance the protection of the internal thread and of a low-strength material. The principle is formed between the screw thread and the elastic connecting base body, thread manufacturing to eliminate errors and improve the bonding strength. A threaded hole embedded wire thread insert engineering materials low strength aluminum, magnesium alloy, iron, steel, glass, plastic and the like, can be accurately formed in accordance with international standards of thread, having a high connection strength, shock, impact and wear-resistant Function, and can disperse stress to protect the base thread, greatly extend the service life of the base, and is widely used in electronic applications.

The wire thread insert is made of high-hardness, corrosion-resistant steel wire with a diamond-shaped cross-section. It is a spring-like concentric body of internal and external threads. The cross-sectional shape of the standard internal thread used for fastening parts is a combination of two internal and external threads. Wire thread inserts are divided into two types: ordinary type and locking type, each with or without breaking grooves and with breaking grooves.


1. Wire thread inserts are used in various low-strength materials, which can greatly improve the wear resistance of screw connections and avoid damage to the connecting threads.
2. Due to the certain elasticity of the wire thread insert, the load distribution on each circle of the thread can be more uniform, eliminate the pitch and tooth form deviation between the screw and the screw hole, and can absorb vibration, thus improving the connection strength and resistance of the thread. Fatigue strength.
3. The locking wire thread insert can lock the screw in the threaded hole, so that the screw will not loosen when it is subjected to shock and vibration, which is better than the normal locking device.
4. Compared with the method of inserting steel or copper bushings, under the same strength conditions, screws with smaller size and higher strength can be selected, which can reduce the volume and reduce the weight.
5. The hardness of the wire thread insert is higher than that of the screw, so it is less worn during the assembly and disassembly process of the screw connection and can be used repeatedly. According to relevant experimental studies, the tensile strength of the wire thread insert is more than 7 times that of the screw, so the wire thread insert will not be damaged even if the screw is broken.


In addition to aerospace and military applications, wire thread inserts are also widely used in civil products such as railway transportation, construction machinery, textile machinery, medical equipment, papermaking, weapons, radar, rockets, ships, steam turbines, and chemicals. In other countries, it is not only used in aircraft, aerospace industry, but also used in ships, automobiles, machine tools, electrical machinery, textile machinery and other industrial and instrumentation. Even in camera, sewing machine, modular furniture and other light industrial products, but also widely used in this wire sets.
