Advantage
Application
1. Enhance connection strength and improve connection conditions. Low-strength materials such as aluminum and magnesium are selected for wire thread inserts, which can avoid slippage and wrong teeth, and obtain excellent connection performance.
2. Wear resistance. Used in frequently disassembled parts, it can greatly improve the service life of the thread.
3. Increase the bearing surface. It is used for parts that require strong connection force and cannot increase the diameter of the screw hole.
4. Anti-loosening. It is especially used in occasions where products such as spacecraft require high insurance coefficients.
5. Easy to maintain. Install the damaged screw hole into the steel wire screw sleeve and continue to use it after repair to avoid the possibility of damage to the workpiece.
In addition to aerospace and military use, 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 foreign countries, it is not only used in aircraft and aerospace industries, but also in industries such as ships, automobiles, machine tools, motors, textile machinery, and instrumentation. Even in light industrial products such as cameras, sewing machines, and modular furniture, this kind of silk cover is widely used.
