What are the applications of stud bolts?

Bolts refer to some screws with larger diameters, and may also have no heads, such as studs. The most common form of studs is threaded at both ends with a smooth rod in the middle. The most typical use: anchor bolts, or similar anchor bolts, thicker connections, and ordinary bolts can not be achieved.
Application of stud bolts:
1. On the main body of large equipment, accessories such as sight glass, mechanical seal, deceleration frame, etc. need to be installed. At this time, using studs, one end of the screw is on the main body, and the other end is fitted with a nut after the attachment is installed, because the attachment is often removed, and the main body and the attachment are directly bolted. Worn or damaged, it is very convenient to use stud replacement.
2. When the thickness of the connector is large and the bolt length is very long, use stud bolts. The purpose of the bolt connection: in actual work, external load vibration, change, material temperature creep, etc. will cause the friction force to decrease, the positive pressure in the thread pair disappears instantly, and the friction force is zero, thereby loosening the thread connection Such as repeated action, the threaded connection will relax and fail. Therefore, it must be loose, otherwise it will affect normal work and cause accidents.
