The appearance of hexagon bolts has brought benefits to many industries because of its good construction strength, concentrated stress and good stress. These advantages lead to the continuous expansion of its application fields. As a user, you should master several of its requirements. What are the specific points? Please see the introduction below:

1. Before use, check whether the design of the friction surface of the hexagonal bolt connection meets the corresponding standard requirements, especially the friction coefficient must meet the requirements, and the friction surface should be free of debris such as iron oxide scale. The treatment of the friction surface should be determined according to the storage conditions and time. Especially on the friction surface of the construction site, it should be noted that there should be no rust, paint, sludge and other pollutants on the friction surface. If the surface is contaminated, it must be cleaned before construction and installation.

2. Pay attention to adjusting the wrench, try to use a torque wrench, because the torque wrench has a torque scale value setting, which can fully meet the construction technical requirements, adjust to the appropriate capacity, and avoid the bolts being too tight or too loose. If the torque value used in the construction process is insufficient, the bearing capacity of the bolt will be reduced, and it will be loosened immediately after a period of use, or simply cannot be tightened. , the time is too long, that is, fracture occurs, and even fracture occurs during the tightening process. Therefore, the torque value error of the torque wrench should be controlled within ±5%. If the working conditions are high, the accuracy requirements are high.
