Recognizing a common fastener: a bolt has a head on one end and external threads along the other, designed to be paired with a nut to clamp parts together. The head provides a stop so the bolt doesn’t pull through, while the threaded portion engages the nut to create clamping force. This differs from a nut, which has internal threads only and no external threads or head; a stud, which has threads on both ends and no head; and a screw, which is typically driven into material or into a threaded hole and doesn’t use a separate nut in the same way as a bolt. So the described part is the bolt.
