HELI-COIL Wire Threaded Inserts are novel and indispencible thread fastening system, provide simple and cost saving for repairing or creating stronger threads. Inserts are precision formed screw thread coils which, when installed into Wire Thread tapped holes, provide permanent and wear resistant thread in parent material i.e. generally stronger than the original thread. The inserts are designed to be greater in diameter than the tapped hole and compress as they are installed. This allows maximum surface contact area with the tapped thread, permanently anchoring the inserts into the place.
The inserts action shares the load over the entire bolt and hole increasing holding or pull out strength. With a Wire Thread Insert in place, load and stress are evenly distributed.
