1. Wire thread inserts are used in various low-strength materials to significantly improve the wear resistance of screw connections and prevent damage to the threads.
2. Due to their elasticity, wire thread inserts distribute the load more evenly across the threads, eliminating pitch and thread profile deviations between the screw and the hole, and absorbing vibration, thus improving the connection strength and fatigue resistance.
3. Locking wire thread inserts can lock the screw in the threaded hole, preventing it from loosening under impact and vibration, offering better performance than conventional locking devices.
4. Compared to using steel or copper bushings, smaller, higher-strength screws can be selected under the same strength conditions, reducing size and weight.
5. Wire thread inserts are harder than screws, resulting in less wear during assembly and disassembly, allowing for repeated use. According to relevant experimental studies, the tensile strength of wire thread inserts is more than seven times that of screws; therefore, wire thread inserts will not be damaged even if the screw breaks.
