Studs in the thread and the transition of the rod will produce stress concentration, high load may break failure. But generally there is no head, only two ends are outside the thread of a class of fasteners. When connected, it must be screwed into the part with internal screw holes, the other end through the part with the through hole, and then screw the nut, even if the two parts are tightened together into a whole. This type of connection is called a stud connection and is a detachable connection. Mainly used for one of the connected parts of a larger thickness, requiring a compact structure, or because of frequent demolition, should not be bolted to the occasion.
