Construction operation technology A bolt is a screw with a larger diameter and may have no head, such as a double-headed bolt. Generally, it is not called "double-headed bolt" but "double-headed stud". The most common form of double-headed stud is threaded at both ends with a polished rod in the middle. Most TYPICAL USE: ANCHOR BOLTS, OR SIMILAR ANCHOR BOLTS, THICK CONNECTIONS, WHEN NOT POSSIBLE WITH ORDINARY bolts. Scope of application 1, used in the main body of large equipment, need to install accessories, such as mirror, mechanical seal seat, deceleration frame, etc. At this time, it is used to screw one end into the main body, and the other end of the nut is installed after the attachment. Because the attachment is often removed, the thread will be worn or damaged, and the replacement of the double head bolt will be very convenient. 2. When the thickness of the connecting body is very large and the bolt length is very long, the double-headed bolt will be used. 3. It is used for connecting thick plates and inconvenient hexagonal bolts, such as concrete roof truss, roof beam hanging monorail beam hanging parts, etc.
