Review: Works and easy to use! - I removed the grab rails off my sailboat to remove layers of varnish and then apply teak oil before re-installing. The nature of these grab rails are that they have 7 stud bolts on each of the two rails and they firmly attach the rails to the top of the cabin - The studs pass thru drilled holes in the Fiberglas and then washer, lock washer and nut hold the rails firmly on top of the cabin. The bolt head end of the stud is not visible - It is inside the top of the rail and wood plugs contoured to the top of the rail hide the bolt heads. These studs should never have to be removed from inside the rail and to do is a chore since the plug would have to be drilled out and a new one installed and contouredmto the rail. Initially, when I removed the nuts from the studs inside the cabin, one of the nuts was had to unthread from the stud and the stud started to rotate within the rail. So, I had to use pliers to hold the stud tight and another set of pliers to unthread the nut. When it was time to re-install the nut, I could not thread it onto the stud. My pliers had ruined the lower threads. I was considering using a diamond cutoff wheel on my Drexel to remove the lower threads but that would leave few threads available to re-install the nut and besides The nut was had to unthread it initially, so I would still be face with that problem as well. I then discovered the EZThread 382 searching the web and desertcart for solutions either by buying a different type of fastener to clamp to the existing threads but then I came across this tool to repair existing threads. The 382 mini-grinder tool was easy to use. It just about 1-2 minutes of use, I was able to get the nut back on. But other threads made it hard to completely re-install the washers and nut, so I tweaked addl threads and kept testing how easy it was to completely install the nut. After only another few minutes of tweaking the threads, the nut washers and nut were able to be re-installed easily. Since I was now able to rethread the nut all the way up to the inside cabin top, the friction fit at the bolt head kept the stud from rotating within the rail and I was able to torque the nut fine. So, this tool not only repaired the initial threads to get the nut on but tweaking the rest of the threads enabled me to utilize the stud, get a tight fit, without having to replace the stud which would have been a much longer repair and would have required labor to replace and contour a new plug on the outside of the rail. This is a great tool ! I am telling all my friends about it !
Review: Thread repair tool - This thing works great for repairing the partially-cut threads of a cheap imported tool that I bought. I just hooked it up to my drill/driver and the shape of this tool fits into the thread grooves easily. Make sure to use light pressure so it doesn’t grab and it works really well. If you have a lot of threads to repair, I’d suggest either buying a few of these or just picking up a proper tap and die set because the crushed diamond abrasive does wear off eventually, but if you have a smaller amount of threads to repair and don’t want to spend the big bucks on a nice tap and die set, this thing is perfect for the job.

### ⭐⭐⭐⭐ Far easier to use than a thread file, but you have to have a steady hand.
*by S***S on August 23, 2024*

Worked great to repair the threads on an irreplaceable part, the hydraulic supply manifold on a 1971 John Deere 510C Backhoe-Loader. New parts are NOT available so repair is the only option. Far faster and easier than using a thread file. User must be careful to ensure the tool only removes damaged material. Tool came with a mounting collet but I could not get it to tighten down and grip the tool shaft, I had to mount it directly without the collet.
