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

    $57.17

    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.
