These self-tapping threaded inserts can be installed directly without threads. Used in low-strength materials such as aluminum and magnesium, they prevent thread damage and achieve good connection performance, while improving strength and connection conditions. Used for parts requiring frequent disassembly, they significantly improve the service life and wear resistance of the thread. They prevent screw loosening, especially for products requiring a high safety factor. Easy to maintain, they allow a threaded insert to be installed in a damaged screw hole, allowing the hole to be used normally, thus preventing the loss of the part.
