"Helicoil" is the original "screw insert" that was born in the United States in the 1930s. We offer two types. ■ Tanged Thread Insert The tanged thread insert provides a permanent and wear-resistant screw thread, eliminating the need for cutting and removal of the tang. It also features a "screw lock" mechanism that prevents loosening under vibration or impact. ■ Tangless Thread Insert The tangless thread insert provides self-locking torque to male components through one or more insert coils. Using a tangless thread insert ensures that no loose tangs remain, making it a solution for critical applications where foreign object debris (FOD) is not present. There is no need for cutting or retrieving the tang, and it can be easily adjusted or removed after installation. In situations where lightweight and strength are required, such as in precision instruments and aerospace components, it reinforces the "weakness of the screw threads" that is a drawback of plastics and aluminum. *For more details, please refer to the PDF document or feel free to contact us.

"Helicoil" is the original "thread insert" that was born in the United States in the 1930s. The outer diameter of the tang thread insert is larger than the diameter of the threaded hole, and by being inserted into the hole, the diameter of the coil decreases. The coil expands with a spring-like action and is permanently fixed in the hole. The screw is then smoothly inserted, and the looseness is tightened. Additionally, to prevent loosening under vibration or shock, it provides an elastic internal locking screw (with a locking mechanism). In situations where lightweight and strength are required, such as in precision instruments and aerospace components, it reinforces the "weakness of the screw threads," which is a drawback of plastic and aluminum. *For more details, please refer to the PDF document or feel free to contact us.
