Antique Rethreading Threader Tool Thread Repair

Unavailable
This is a rare antique thread repair tool, for repairing outside threads on machine bolts or screws. The tool is hardend around the threads so you can run the screw into on of the threaded holes on the thread plate to cause damaged threads to be forces back into the same thread pattern has they once were. Not a common tool, in fact very rare in this size. The threaded holes range from around 1/16" to 3/16", and the thread per inch appear to be standard national course threads. The tool is shaped much like a spatula so the handle give clearence in the event of a screw stud extending upward from a flat plate needing repaired, in this case the user can use the leverage of the handle without interference with the stud plate. The thread all check out good except for the largest one has some tiny chips off at the thread start point. As you can see there is also some pitting on the steel, otherwise no damage, no rust, clean. A rare thread screw plate tool!
