The insert went in without a hitch into the tapped hole. The tap was very smooth and cut easily. Helical coil also went in very well. Had to remove the rubber boot on the punch tool as I had to go through the bolt hole on opposite side. New bolt threaded in just tight enough as not to worry. Will definatley use this again.

I will buy another set if I need it **Q: What’s the installed thread length of the inserts? Specifically 5/16-18** A: Did not measure the insert length, but most inserts are approx 1/2" long in this size range. It only has to be as long as the diameter of the boat to be full strength. So if it is a 5/16 insert the insert needs to be at least 5/16 long. These are. But the tool is junk, I suggest buying a name brand US. Made tool. **Q: will this work on .9 thread?** A: This kit is for 5mm . **Q: If the thread id of the helicoil is m8x1.25, so what is the od of that helicoil?** A: You purchase the kit you need depending on the thread type you are attempting to repair. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Quality was very good, drilled aluminum like butter *by P***. on 9 January 2026* I had doughts with this set... but surprised me, bolt snapped in an alternator... was able to drill it out with the provided drill bit, bit of wd40 and went silky smooth.
