Thread Repair Kit M5-M12 131pc Helicoil Type Insert Set

A 131-piece thread repair kit for restoring damaged or worn metric threads in common sizes from M5 to M12. This helicoil type kit includes the inserts and fitting tools needed to repair stripped threads in metal parts without replacing the full component.

Used for garage work, workshop repairs, vehicle maintenance and general servicing, it suits anyone dealing with damaged threads in engine parts, housings, brackets and other threaded fixings. Handy for mechanics, engineers and DIY users, it helps when bolts no longer tighten properly or original threads have been pulled, cross-threaded or worn through repeated use.

The kit covers five common metric thread sizes: M5, M6, M8, M10 and M12. Included are 5 installation tools, 5 break pin tools, 5 twist drills, 5 taps and 1 hex key, along with the wire thread inserts for each size. Having the drills, taps and fitting tools together makes the kit more straightforward to keep ready for regular repair work, especially when dealing with different thread sizes across workshop or vehicle jobs. It is a practical option for repeated maintenance where damaged threads can hold up a repair.
