One of the biggest misconceptions regarding locking type helical coil screw thread inserts is the insert has a feature that locks it into place in the parent material. This is not the case. Locking inserts apply a locking, or prevailing, torque on the male fastener.
Product performance
Performance of wire thread inserts
Wire thread inserts are a new type of connection and fastening technology. They can effectively improve the connection conditions when screwing and greatly improve the reliability of screw connection. Its advantages are as follows:
1. Wire thread inserts are used in various low-strength materials, which can greatly improve the wear resistance of screw connection and avoid damage to the connecting thread.
2.Because the wire thread insert has a certain elasticity, the load distribution on each circle of the thread can be relatively uniform, the pitch and tooth deviation between the screw and the screw hole can be eliminated, and vibration can be absorbed, thereby improving the connection strength and fatigue resistance of the thread.
3. The locking wire thread insert can lock the screw in the threaded hole, so that the screw will not loosen when subjected to impact vibration. The process performance is better than that of the usual locking device.
4. Compared with the method of inlaying steel or copper bushings, under the same strength conditions, smaller and higher-strength screws 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 wears less during the assembly and disassembly process of the screw connection, and can be used repeatedly. According to relevant test research, the tensile strength of the wire thread sleeve is more than 7 times that of the screw. Therefore, even if the screw breaks, the wire thread will not be damaged.

Application range of wire thread inserts
In addition to aerospace and military applications, wire thread inserts are also widely used in railway transportation, construction machinery, textile machinery, medical equipment, papermaking, weapons, radar, rockets, ships, steam turbines, chemicals and other civilian products. Abroad, it is not only used in the aircraft industry, but also in industries such as ships, automobiles, machine tools, motors, textile machinery and instruments. Even in light industrial products such as cameras, sewing machines, and modular furniture, this wire thread insert is also widely used.
