ASME standards cover a wide variety of machine screws, typically ranging up to 0.75 inches (19.05 mm) in diameter. These fasteners are often used with nuts or driven into tapped holes. Depending on size, they may be referred to as screws or bolts. In practice, smaller sizes are commonly known as machine screws, while some types are also called stove bolts.
