Stud bolts are bolts with threads on both ends of the screw. Headless bolts with a part of the polished rod in the middle are also called studs or studs. The middle straight rod of this type of bolt is thick or thin, and is called straight rod or shrink rod. Stud bolts have the function of fixing the connection. Due to the long length of the bolts, they are generally used where the thickness of the connecting body is large and the connection cannot be realized by ordinary bolts. Such bolts are generally used in automobiles, motorcycles, boilers, steel structures, suspended towers, and large buildings. High-strength stud bolts are made of 45#, 40Cr, 35crMo and other materials.

The reference standards for bolts are: National Standard (GB/T), German Standard (DIN), American Standard (ANST/ASME), British Standard (BSW), Japanese Standard (JIS), International Standard (ISO) and so on.
