I was taught the opposite:  bolts are fasteners that have only partially 
threaded shanks and those with fully threaded shanks are cap screws.  A bolt 
relies on a nut for its fastening capability, whereas a screw fastens by 
engaging with a tapped hole in the piece to which it is securing something.
