Bolts especially refer to screws with larger diameters, and they can also have no heads, such as stud bolts, which are usually double-ended bolts or double end studs, threaded rods. Which are the thread in the two ends, with a polished shank in the middle, typical use: Anchor bolts, or similar to anchor bolts, in thicker connections, when ordinary bolts cannot be used.

The application of double end studs: When the thickness of the connecting part is very large and the length of the bolt is very long, the stud bolt will be used to achieve the purpose of anti-loosening: in actual work, vibration, change of external load, high-temperature creep of the material, etc. will cause friction decrease. The positive pressure of the thread centering disappears at a certain moment, and the friction force is zero, so the threaded connection is loosened. If the operation is repeated, the threaded connection will loosen and fail, so it is necessary to prevent loosening, otherwise, it will affect normal work and cause accidents.

When the main body is a piece of large-scale equipment, it is necessary to install accessories, such as observation mirrors, mechanical seal seats, deceleration frames, etc. At this time, one end of the stud bolt used is screwed into the main body. After the accessories are installed, the other end is equipped with a nut. Disassemble the accessories, when the main body and accessories are directly connected by bolts, the main body screws will wear or become damaged over time, it is very convenient to use the stud bolts for replacement.

Maintenance of stud bolts: In actual work, the stud bolts will rub repeatedly, and their threaded connections may loosen and gradually lose their function, so the relevant personnel needs to do a good job in the maintenance of the stud bolts.

When large-scale equipment is running, it is necessary to observe its working status at all times. Once there is abnormal noise and equipment instability, it is necessary to stop the operation immediately and start inspection; during the maintenance of stud bolts, relevant personnel needs to carefully check the connection of stud bolts and other accessories to avoid major problems.
