I always try to remember to thread on a regular nut anytime I have to cut a screw or bolt to length, because even when I grind or file the threads, I may leave little burs or deformation caused by the cutter or hacksaw. The quick and easy action of unscrewing the nut cleans up the cut end of the threads so they will start easily when I use the screw.
