A stud bolt is a headless fastener with external threads at both ends. It is primarily used to connect thicker components or in applications requiring frequent disassembly. One end screws into a threaded hole in the bolt body, and the other end is secured with a nut.
Unlike bolts, studs have no head, so they do not require a wrench for direct tightening. Instead, the connection is achieved through the engagement of the threads at both ends with a nut. This design makes them suitable for space-constrained or compact applications. Common types include double-end studs and welded studs.
Studs perform excellently under high temperature and pressure conditions and are widely used in petroleum, chemical, power, pressure vessel, valve, and offshore platform industries. For example, the A193 B7 stud can operate stably at temperatures up to 450°C, exhibiting high strength and good corrosion resistance.
