Review on πŸ’ͺ Ext Thread Repair Tool 5/32-3/4 In: Enhanced Efficiency for Threaded Repairs by Kenji Townsend

Revainrating 5 out of 5

got a job! . (Over time)

I had a screw (more like a threaded bolt) that attached the gear box to the jack frame of an old Craftsman jack model 328.12002 (made in Japan). It is over 32 years old and I have renewed the hydraulic cylinder. I messed up the thread on the pin by stupidly twisting it. At first there are only about 6 threads at the end of the pin. If your entry thread is damaged, you should probably place a tool next to the head of the bolt on the good thread and pull it back to try to "squeeze" and separate the entry thread. I ran the tool over it about 6 times and it removed quite a bit of material. I kept finding the thread pushed into the crumpled thread, but kept sticking the cutter tooth of the tool (in my case only one tooth made contact with the thread because my threads were so short) between the crumpled threads and always worked it again. (I think my thread is M18x1.5). In the end it worked and I was able to assemble the jack and tighten the bolt. I was really amazed that it worked because after the first few runs I got pessimistic. I just pinned him. I didn't tighten it to 80 pounds or so. I think most of the stress on the pin is shear. If it doesn't hold up I'll weld the bolt head to the frame and hope the piston seal will last another 30+ years. (In the photo "before".) I didn't forget to take a photo "after". before I assemble it. (sorry) Bottom line - Nice tool. The dough is worth it and worth trying.
