The simple answer is: The difference between bolts and screw are the applicable standards which define the requirements for the threads, and the applications they are used/intended for. The official definitions are (Reference Machinery's): "A bolt is a externally threaded fastener designed for insertion through holes in assembled parts, and is normally intended to be tightened or released by torquing a nut." "A screw is an externally threaded fastener capable of being inserted into holes in assembled parts, of mating with a preformed internal thread or forming its own thread and of being tightened and released by torquing the head." There are separate standards available for both bolts and threads, as well, as the grips, heads, ect.. Modified by Kelly_Bramble at Fri, Jun 16, 2006, 16:00:54
