ABSTRACT:
A device for the timely and accurate inspection of and polishing of large threaded bolts. The device is easily reconfigured for effective use on a large number of different sized bolt threads by replacing the polishing stones, depending on the dimensions of the particular bolt thread. After a metal layout dye is placed on the bolt threads the rotating polishing stones reveal the upset and damaged threads that must be repaired before replacing the corresponding nut.
