  • Heli-Coil® Thread Repair Kits, Inch Coarse Thread (UNC)


    When installed into Heli-Coil® STI tapped holes, inserts provide permanent conventional 60° internal screw threads that accommodate any standard bolt or screw. Heli-Coil threaded inserts boast a high wearing tensile strength, low thread friction with tight tolerances, and a high surface quality as well as corrosive- and heat-resistant properties. With Heli-Coil threads, tapped holes are strengthened and thread life is dramatically increased even after repeated assembly and disassembly. Tapped holes are easily incorporated into existing designs.

    Individual Size Kits
    Heli-Coil inserts are available in individual size kits in inch, metric, and pipe thread series. All kits have a quantity of inserts, the proper size drill, high speed steel Heli-Coil tap and an installation tool. The Professional Kits* also include a tang removal tool and qtys of 3 lengths of inserts.

    * The total quantity of inserts in the Professional Kits represents 3 lengths.
