1. It is used for large-scale equipment, and accessories need to be installed, such as sight glasses, mechanical seals, reduction gears, etc. At this time, the double-headed bolts are used, one end is screwed into the main body, and the other end is equipped with a nut Because the attachment is often disassembled, when the main body and the attachment are directly connected by bolts, the main body's screw teeth will be worn or damaged over time, and it will be very convenient to replace them with stud bolts.

2 . When the thickness of the connection body is very large, when the bolt length is very long, a stud bolt will be used.

The purpose of anti-loosening of stud bolt connection: In actual work, vibration, change in external load, high-temperature creep of the material will reduce friction, and the positive pressure of the thread pair will disappear at a certain moment, and the friction force will be zero, thereby making the thread connection Loose, if repeated action, the threaded connection will loosen and fail. Therefore, it is necessary to prevent loosening, otherwise it will affect normal work and cause accidents.
