M8 x 1.25 mm Stainless Steel Metric Thread Repair Kit - 30 Pieces - Compatible Hand Tool Kit for Automotive Repair

The thread repair kit includes threaded inserts, a drill bit, a tap, an insert installation tool, and a hull remover for quick and easy repairs. It contains 25 M8 x 1.25 mm threaded inserts, perfect for repairing damaged threads, stripped internal threads, and creating stronger internal threads in soft metals. Drilling: Clean the damaged threads with a standard drill bit. (For spark plug thread repair, no pre-drilling is necessary if you use the special spark plug tap.) Note that for taps without flutes, larger holes are required. Insert Installation: Place the insert onto the installation tool and position the adjusting ring so that the insert stem is centered in the groove. Wind the insert, applying slight downward pressure, until it is half a turn below the surface. Do not work in the direction of the thread, as the stem may break. Multiple Uses: Ideal for repairing damaged or worn threads, this kit is suitable for engines and other automotive repairs. It can be used for general repairs, automotive repair, and drills.
