A machine screw, also called a stove bolt, is generally a smaller fastener threaded the entire length of its shank. Machine screws are used in fastening nearly all types of hard materials. Especially useful in metal-to-metal or where heavy duty fastening is required. Commonly used with flat or lockwashers.
