10 reviews for Ext Thread Repair Tool, 5/32-3/4 In

  1. C. Brannon

    Used it to clean bad threads on a motorcycle transmission shaft (unable to get the nut started onto the shaft). In less than a minute I had the threads cleaned and the left hand nut on properly. This tool works much better than a die. It was able to clean/straighten the threads on the end of the shaft. I would recommend this tool. A must have it you ever have a nut that tries to cross thread.

    I made the mistake of using a universal shift on my car and even though I used tubing to protect the thread the little allen screws tore into my shift stick. When I purchased a nice knob designed to fit my shifter it wouldn’t even begin to screw on due to the mangled mess left behind. I hopped on amazon and after reading a few reviews I got this. It worked as well as I could’ve hoped! I went over it for maybe 5 minutes with this and it fixed years of abuse! I know I will have plenty more to use this on and I’m so happy I made the purchase.

  3. Michael J. Hertel

    I was rebuilding a transmission from an old photo booth when I discovered the 1/2″ X 20 left hand thread end of the main drive shaft was damaged. I asked fro a 1/2″ left hand thread dye at a large hardware store but they didn’t have one. I found this thread restorer on Amazon and although it was quite expensive I decided to try it and the damaged part was not available. Although it took some time, about a half hour, I was able to salvage the shaft. Just make sure the size range will work for your project. It is a very well made tool and should last many years.

    Love this tool I have the one size larger and it’s just as nice I don’t know how long the blades last still on originals

    This thread repair tool works as advertised if not better! It is made of all steel so very rugged. Working on restoring an old 1978 Goldwing motorcycle, most parts are no longer made. I repaired 2 lower/forward engine hanger bolts (double thread stud) which also fasten the engine guard to the engine and frame. One of the tips was partially stripped from where the guard was put to use during an accident. All 4 threads were damaged from the engine guards resting on the threads for decades. At first I was cautious by continuously attaching the tool for every spec of damaged thread not wanting to start a new thread. Every time I lined up a tooth in a groove, the other tooth lined up perfectly in another groove to guide it. It was a bit time consuming but it worked. Then after done sometimes screwing the nut on was a bit tight in spots, this is when I just attached the tool and traced the entirety of each thread in one shot, both bolts are perfect again! Just put your bolt in a vise with a sliced piece of auto hose around it, oil the threads, check that both teeth are lined up in good threads, tighten, then begin rotating the tool through the damaged area. The tool works in push fashion so you should always be pushing the tooth across the bad thread, not pulling it. In other words the bad piece of thread to repair should be out in front of the tool rotating towards it. Need to come at the damaged thread from other direction, simply turn the tool around. It will either bend/reshape threads or in some cases slightly shave it so be aware of little pieces. Comes complete in easy to open and store package along with clear instructions. Money well spent, easy 5 *’s.

    I had a bolt (more like a threaded pin) that held the gear assembly to the jack frame on an old Craftsman Model 328.12002 Floor Jack (Made in Japan). It’s easily 32+ years old and I rebuilt the hydraulic cylinder. I buggered the threads on the pin by stupidly cross-threading it. It only has about 6 threads on the end of the pin, to begin with. If your lead-in threads are damaged you should probably place the tool near the bolt head on the good threads and back it off in an attempt to ‘un-crush’ and separate lead-in threads. I ran the tool over it about 6 times and it removed quite allot of material. I kept finding thread area that was compressed in crushed into the next thread, but I continued placing the tool’s cutting tooth (only one tooth contacted the thread area in my case since my threads were so short) between the crushed threads and running it over and over. (I believe my thread is M18x1.5) Eventually, it worked and I was able to reassemble the jack and tighten the bolt. I was actually amazed it worked since I was growing pessimistic after the first few passes. I just snugged it down. I didn’t torque it to 80ft lbs or anything. I think most of the stress on the pin is a shearing force. If it doesn’t hold, I’ll weld the bolt head to the frame and hope the ram seal lasts another 30+ years. (Picture is the ‘before’ picture…) I didn’t remember to take an ‘after’ pic. before I assembled it. (sorry) Bottom Line- Nice Tool. Well worth the dough and worth a try.

    My first impression was to be a bit unimpressed with the packaging and the item itself. I seem to remember saying to myself, “This is it? I paid $50-something for this?” I had bought this for some 4′ lengths of all-thread that I was cutting on an abrasive chop saw as I was getting tired threading a nut on a 10′ rod and running it some 4′ up to just the other side of where I was cutting just so I could chase the threads.First impressions aside, this little thing does work great. Each time I used it, it quickly settled into the thread grooves and easily chased the threads out for me- I really couldn’t ask for more.

    I probably saved $50 in a few hours retreading some large bolts that I refused to throw away. Bolts cost so much today and continue to go up.

    This tool is great, worked perfect. Will never be without one now.
