Helicoil - Kit M11X125 5543-11

The Helicoil Metric Thread Repair Kit is a useful tool for anyone dealing with stripped screw threads. It comes with 12 coils and one tap, which is a specialty tap to work with the Helicoil. The length of the thread insert is around half an inch, making it unsuitable for those who need a longer insert. It's worth noting that this kit is designed for metric fine thread repair and won't fit bolts with a coarse thread pitch. Customers have reported mixed experiences with the Helicoil Metric Thread Repair Kit. Some have found the kit to be a waste of money, as the insert is only suitable for larger bolts. However, others have had positive experiences, with one user reporting that the Helicoil threads are at least three times stronger than the original cast threads. Overall, if you're dealing with stripped screw threads, the Helicoil Metric Thread Repair Kit could be a useful addition to your toolkit. However, be sure to double-check that the thread size and pitch is suitable for your needs before purchasing.
