Stripped a thread? Don't panic, repair it! This professional 15-piece kit lets you fix damaged M10 x 1.0mm threads in metal like steel, aluminium, or cast iron. It's perfect for common automotive repairs on engines, manifolds, or anywhere threads get worn out. The kit includes 10 stainless steel wire thread inserts (helicoil type), which actually create a thread stronger than the original. You also get all the tools you need: the correct size drill bit, a tap, an installation tool, a tang break-off tool, and a hex key. Just drill out the old thread, tap new threads, screw in the coil insert, and break off the tab. Good as new, maybe even better. A must-have for any serious DIY mechanic or workshop.
