Next, insert the Helicoil tool into the damaged thread and apply the appropriate torque to seat the insert securely in place. The Helicoil insert will conform to the damaged thread and provide a new, strong, and functional thread. Finally, retap the repaired thread to ensure a proper fit with the mating component.
