Stud bolt Industry Knowledge Extension

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, reducer rack, etc. At this time, stud bolts are used, one end is screwed into the main body, and the other end is equipped with a nut after the accessories are installed. Since the accessories are often disassembled, the thread will be worn or damaged, and it is very convenient to use the stud bolts to replace them.

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.

Surface treatment of stud bolts

Stud bolts generally require surface treatment. There are many types of bolt surface treatment, and the commonly used ones are electroplating, blackening, oxidation, phosphating, and non-electrolytic zinc flake coating treatment. However, electroplated fasteners occupy a large proportion in the actual use of fasteners. It is especially widely used in industries and fields such as automobiles, tractors, home appliances, instruments, aerospace, and communications. However, for threaded fasteners, it is not only required to have a certain anti-corrosion ability, but also to ensure the interchangeability of threads, which can also be referred to as screwability here. In order to meet the dual performance of "anti-corrosion" and "interchangeable" required by threaded fasteners in use, it is very necessary to formulate special electroplating standards

How to maintain the stud bolts?

Generally, known bolts refer to screws with a larger diameter. According to this statement, the diameter of a screw is much smaller than that of a bolt. The stud has no head, and some are called studs. Both ends of the stud bolts are threaded, the middle does not contain threads, and the middle is a bare rod. Stud bolts are used on large equipment such as reduction racks. In actual use, the external load will vibrate and the influence of temperature will cause the friction force to become smaller, and the threaded connection will loosen and fail over time. Therefore, it is necessary to do a good job in the maintenance of stud bolts in normal times. Stud bolts or anchor bolts will have problems under the action of mechanical friction for a long time. When problems occur, the engine oil pan must be removed, and the use of the engine bearing bushes should be carefully checked. Check the gap between the bearing bushes Whether it is too large, if the gap is too large, it must be replaced in time. When replacing the stud bolts, also replace the connecting rod bolts. Some large-scale equipment such as nail making machines should stop and check in time if the engine is not running very stably or there are abnormal noises during normal operation, so as to avoid bigger problems.
