Overview of Stud Bolts

1. Overview of stud bolts Bolts refer to screws with larger diameters, and they can also have no heads, such as stud bolts. Generally, it is not called a stud but a stud. The most commonly used form of double-ended studs has threads on both ends and a polished rod in the middle. The most typical use: anchor bolts, or places similar to anchor bolts, thick connections, when ordinary bolts cannot be achieved.

2. Marking of the specification of stud bolts Thread specification du003dM12, nominal length Lu003d80mm, performance to be graded is 4.8. Equivalent length stud bolts are completely marked as: GB/T901M1280 (Guide: Stainless steel numbering principle)

3. The application of stud bolts 1. It is used in the main body of large equipment, which needs to install accessories, such as sight glass, mechanical seal seat, reduction frame, etc. This is the stud bolt used, one end is screwed into the main body , After installing the accessory, put a nut on the other end. Since the accessory is often disassembled, the thread will be worn or damaged. It is very convenient to replace it with a stud. 2. When the thickness of the connecting body is very large and the length of the bolt is very long, stud bolts will be used.

4. The purpose of anti-loosening of stud bolt connection. In actual work, external load such as vibration, change, high temperature creep of material will reduce friction, and the positive pressure in the thread pair will disappear at a certain moment, and the friction will be zero. As a result, the threaded connection becomes loose. If repeated action, the threaded connection will become loose and fail. Therefore, it is necessary to prevent loosening, otherwise it will affect normal work and cause accidents.
