Tangless thread insert overcomes the shortcomings of traditional thread insert installation handle and low installation efficiency. The slotting position of the traditional thread insert mounting handle cannot be controlled accurately, resulting in the phenomenon that the tail is not easy to break or is too easy to break. When the handle is removed, the tail end is easy to protrude, which affects the screwing of the thread, and affects the product quality in severe cases.

Tangless thread insert adopts threaded rotary hook type installation tool, which fully considers the efficiency of installation, and the installation does not need to remove the handle and has no directionality.
