Usage: 1. When the main body is large equipment, accessories need to be installed, such as sight glass, mechanical seal seat, deceleration frame, etc. At this time, a stud bolt is used, one end is screwed into the main body, and the other end is equipped with a nut after the accessory is installed. Since the accessory is often disassembled, the thread will be worn or damaged, and it is very convenient to use the stud bolt to replace.

2. When the thickness of the connecting body is very large and the bolt length is very long, stud bolts will be used.

3. It is used to connect thick plates and places where it is inconvenient to use hexagonal bolts, such as concrete roof trusses, roof beam suspension monorail beam suspension parts, etc.

Anti-loosening purpose
In actual work, external loads such as vibration, change, and high temperature creep of materials will reduce the friction force. The positive pressure in the thread pair disappears at a certain moment, and the friction force is zero, thus making the threaded connection loose. will relax and fail. Therefore, it is necessary to prevent loosening, otherwise it will affect the normal work and cause accidents.

The main purpose of stud bolts

1. When the main body is large-scale equipment, accessories need to be installed, such as sight glass, mechanical seal seat stud bolts, deceleration frame, etc. At this time, a stud bolt is used, one end is screwed into the main body, and the other end is equipped with a nut after the accessory is installed. Since the accessory is often disassembled, the thread will be worn or damaged, and it is very convenient to use the stud bolt to replace.

2. When the thickness of the connecting body is very large and the bolt length is very long, stud bolts will be used.

3. It is used to connect thick plates and places where it is inconvenient to use hexagonal bolts, such as concrete roof trusses, roof beam suspension monorail beam suspension parts, etc.

Main applications of studs

1. When the main body is large-scale equipment, accessories need to be installed, such as sight glass, mechanical seal seat, deceleration frame, etc. At this time, the double-ended stud is used, one end is screwed into the main body, and the other end is attached after the accessories are installed. Nuts, because the accessories are often disassembled, when the main body and the accessories are directly connected by bolts, the main body threads will be worn or damaged over time, and it is very convenient to use studs to replace them.

2. When the thickness of the connecting body is very large and the length of the bolt is very long, the double-ended stud will be used.

The purpose of anti-loosening of stud connection In actual work, the external load has vibration, change, high temperature creep of materials, etc., which will reduce the friction force, the positive pressure in the threaded pair disappears at a certain moment, and the friction force is zero, thus making the threaded connection loose. , if repeated action, the threaded connection will loosen and fail. Therefore, it is necessary to prevent loosening, otherwise it will affect the normal work and cause accidents.
