Premium Material: This new type of iron wire repair insert is made of high quality stainless steel, which has higher hardness than normal screws, and is strong and enough to provide repeated use and frequent disassembly Great Elasticity Provides Better Performance: This type of iron wire insert can make the thread more uniform, because it has a certain and strong elasticity. It can eliminate the deviation of the screw and the screw hole between the pitch type and the tooth type, and can also absorb vibration, thereby increasing the thread connection strength and fatigue resistance. Anti-loose Design: This insert thread is a new type of fastening technology, which can effectively improve the connection conditions and greatly increase the reliability of the screw connection. And the locking type threaded sleeve can lock the screw in the threaded hole, so that the screw will not be loose when subjected to shock vibration, which is better than the normal locking device Widely Used: This iron wire insert has wide applications in daily life. The thread inserts can be applied to repair stripped threaded hole, and it is mainly used in various low-strength materials, which is helpful to improve the wear resistance of bolt connections and avoid thread damage. Strengthen the connection: The metal wire repair inserts can strengthen the connection strength and improve the connection condition, which can avoid the slipping thread and bad tooth phenomenon, thus achieving excellent connection performance
