Machine Screws (square)

Machine Screws are uniformly threaded screws which are designed to be screwed into pre-drilled, pre-threaded holes, or in conjunction with a nut, usually with a diameter less than 1/4inch. Larger diameter machine screws with a hex head are usually referred to as machine bolts.
