ASME standards specify a variety of "Machine Screws"[9] in diameters ranging up to 0.75 in (19.05 mm). These fasteners are often
used with nuts as well as driven into tapped holes. They might be considered a screw or a bolt based on the Machinery's Handbook
distinction. In practice, they tend to be mostly available in smaller sizes and the smaller sizes are referred to as screws or less
ambiguously as machine screws, although some kinds of machine screw can be referred to as stove bolts
