Review on 🔧 HeliCoil 5621 Thread Repair Kit: Optimal Solution for Thread Repairs by David Edwards

I ordered a set of Helicoil (HEL5621) Master Inch Coarse Thread Repair Kits to repair a stripped threaded hole used to tighten a button head screw that was preventing sliding controls component on some machines. It was a threaded hole in the steel that was uncovered several times and I re-enlarged the thread and used a larger screw. The metal was too soft for this purpose so I used a coil and everything worked fine even though it was my first time doing this. (I watched a few YouTube videos on how to do this.) The hardened steel spool creates filament that will likely never fray again. Highly recommended for anyone with a general knowledge of threading and average or above common sense.
