Features HIGH QUALITY MATERIAL: Steel thread inserts It is made of stainless steel wire with high strength, high precision and smooth surface. It is a high precision inner and outer screw concentric body. used in low strength materials such as aluminum, magnesium, can avoid thread damage and get a good connection performance, to enhance connection strength and improve connection condition ABSORB VIBRATION: Because of a certain elasticity, thread insert can even the load distribution on each thread, eliminate pitch and tooth deviation between screw and screw hole, and absorb vibration, thus increasing the screw thread connection strength and fatigue resista STANDARD THREAD: The Thread Repair Inserts ​can prevent screw from getting loose,especially used for products requiring high coefficient of insurance. Screw it into a low-strength material to form a high-strength, wear-resistant, interchangeable standard internal thread. It is superior to all internal threads formed by tapping directly with taps EXCELLENT DURABILITY AND WEAR RESISTANCE: The thread insert repair is used for parts that requires frequent removing, it can greatly improve service life and wear-resistance of screw thread. improve the durability of the screw and prevent loosening and fatigue fracture of the screw due to various vibrations WIDELY APPLICATION: The thread repair insert kit is easy to maintenance, install a thread insert into a damage screw hole, then the screw hole can be used as normal, in order to avoid workpiece loss. In the case of threading errors or repairs to damaged internal threaded holes, the use of wire threaded sleeves as a means of repair allows economical repairs, saves critical parts, and repairs to the original state quickly and efficiently without adding weight and volume.
