A stud bolt is a straight rod-type fastener without a head, with external threads on both ends or on one end, and typically a smooth, threadless shaft in the middle. Stud rod and double end stud are other names for stud bolts, which are suitable for applications requiring high-strength connections, adjustable lengths, or frequent disassembly.
