How To Cut Bolts Without Damaging the Threads

Have you ever cut a bolt only to discover the threads have been damaged and won’t accept the nut? You don’t need a machinist’s die to re-thread the bolt. Next time, twist the nut onto the bolt before you cut it. Use a file to ease the cut edges of the bolt. This will make it a little easier to re-thread the nut later. When you remove the nut it will repair the damage to the threads.
