[REDCRO_REDNECK]

Most bolts produced today are rolled thread not cut like years ago. The shoulder on a rolled bolt is smaller than the major dia. of the threads.

Actually they are the same size. If not the bolt blanks would have a step down forged into them where the threaded portion stops and the shank begins.
