1) Drill out damaged threads
2) Turn hex nut onto cap screw, follow by threading the GARDSERT® onto the cap screw, and be sure to keep the cutting holes open.
3) Carefully align the GARDSERT® to the hole and turn inot the hole clockwise using a wrench on the hex nut. Bottom out assumbly on the work piece. Hold the cap screw and loosen the hex nut, turning counter-clockwise. You now have a completely threaded hole and a solid repair.
