Want to connect two separate steel structures together, there must be a medium in the middle, bolts are this medium, and there are many types of bolts, depending on the size of the capacity, it can be divided into ordinary bolts and high strength bolts, and Hexagon Flange Bolt is a very famous in bolts, but it is not easy to use, today Xiaobian gives you a brief introduction to the steel structural components.

1. For the hex bolts of the moving load or installed in an important part, the spring washer should be placed according to the design requirements, and the spring washer cannot be placed at will, and should be placed on the side of the nut.

2, when installing high strength hex bolts. Bolts should be able to unblocally penetrate into the gap, if the size position of the hole is not suitable, it is not forced to penetrate. If the aperture is found to be smaller than the diameter of the bolt, it is necessary to use the electric drill to drill the aperture.

3, depending on the connection, high-strength hex bolts can be roughly divided into three categories, namely friction connectivity, tensile connection, and pressurized connection. At present, most applications are frictional connections.

4, hex bolts There are their own installation sequence. When installing, it should require gradual advancement from the locations with large stiffness to unconstrained free ends. From the initial screw, twisted to the final screw should be screwed from the intermediate to tighten according to the order, and you can sit on each time it is screwed, so you can avoid a stop drainage phenomenon. The bolts of the same part should be installed within one day,

It can be seen that the installation of the steel structure Threaded Rods And Eye Bolts is not so simple, no matter what, install any bolts, should strictly abide by the installed process.

　　 I believe everyone knows that Hexagon Flange Bolt do not need nuts, but did you know? In fact, stainless steel screws and nuts cannot be used together. What is going on?

Why can't stainless steel screws and nuts be used together?

　　 When we are assembling two objects, we use stainless steel screws and nuts to fasten them. Once time passes, you will find that the screws and nuts will seize.

　　 This is because after tightening, the threads and bolts of stainless steel screws will be structurally deformed.

In addition, after a long time, the Threaded Rods And Eye Bolts and the screw holes will merge, so it is not easy to disassemble the screws and nuts in the future. Therefore, if two or more products are assembled, stainless steel screws are not recommended. Used in conjunction with the nut.

1. Cleaning and polishing: If it is damaged, it should be polished, especially scratches and splashes caused by contact with Hexagon Flange Bolt, and damage caused by cutting slag. It must be carefully and thoroughly cleaned and polished.

2. Mechanical polishing: Use suitable polishing tools for polishing, and require uniform treatment to avoid excessive polishing and re-scratches.

3. Degreasing and dust removal: Before pickling and passivation of stainless steel parts, oil, oxide scale, dust and other sundries must be removed according to the process.

4. Water blasting treatment: According to different treatment requirements, choose different micro glass beads and different process parameters to avoid over-spraying.

5. Pickling passivation: The pickling passivation of stainless steel parts must be passivated in strict accordance with the process requirements.

6. Washing and drying: After pickling passivation, neutralization, washing and drying should be carried out in strict accordance with the process to completely remove residual acid.

7. Protection: After the surface treatment of stainless steel parts is completed, protection should be done to avoid secondary pollution caused by personal contact, oil, dust and other sundries.

8. Avoid reprocessing: After finishing the surface treatment of Threaded Rods And Eye Bolts, avoid reprocessing parts or products

Threaded Rods And Eye Bolts have taken a pivotal position in today's industrial production. Product quality must not be carelessly produced and accepted in strict accordance with the corresponding standards. What are the acceptance standards for Threaded Rods And Eye Bolts?
1. First of all, Threaded Rods And Eye Bolts are also the evolution of the national standard screws. The specific inspection items should also be determined according to the national standard screw surface defect standards. Please refer to the corresponding national standards for details. If the surface coating or plating affects the surface defects Identification, it should be selected before inspection.
2. Check the dimensions and material of Threaded Rods And Eye Bolts according to the requirements of the design drawings. This should pay attention to the material detection:
One: The raw material manufacturer is required to provide a material certificate report.
Two: High-end products must require SGS material certification and send to relevant laboratories for material composition analysis to confirm whether the composition content meets the material requirements of the drawings.
3. During the non-destructive inspection of Hexagon Flange Bolt, if any part of the quenching cracks, wrinkles on the supporting surface and below are found, and whether the coating meets the Rosh environmental protection requirements.
4. For Hexagon Flange Bolt hardness level, do the corresponding hardness impact test; internal hardness, mechanical properties, torque test, etc. will damage the Hexagon Flange Bolt, but for the screw factory with a strong concept of quality, this is a must for testing .

1. Hexagon Flange Bolt view the solder joints. The LED lanterns produced by conventional LED lantern manufacturers adopt SMT SMT process, solder paste and reflow soldering process. Therefore, the solder joints on the LED lantern are relatively lubricated, and the amount of solder is not too much. The solder joints are curved. From the beginning, the structure of the maintenance layer should pay attention to tightness and small pores.



2. The maintenance layer is evenly distributed and has a certain thickness.



3. The maintenance layer of Threaded Rods And Eye Bolts is firmly separated from the base metal and has good adhesion.
