A stud is a type of fastener with no head, featuring threads on both ends. During assembly, one end must be threaded into a component with an internal threaded hole, the other end passes through a component with a through hole, and then a nut is tightened to securely join the two components into a single unit. This type of connection is known as a stud connection and is also a detachable type. It is mainly used in situations where one of the connected parts is thick and requires a compact structure, or where frequent disassembly is not suitable for bolt connections.
