Hex Bolt Manufacturers Introduces The Use Strategy Of Bolts

Dec 17,2021 / Industry News, News / Author: ShengKui

The emergence of hexagonal bolts has brought benefits to many industries because it has good construction strength, concentrated stress, and good stress. Next, Hex Bolt Manufacturers introduces the strategy of using bolts:


1. Before use, whether the design of the friction surface of the hexagonal bolt connection meets the requirements of the corresponding standards, 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 the friction surface of the construction site, pay attention to the friction surface without rust, paint, sludge, and other pollutants. If the surface is contaminated, it must be cleaned up 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 set, which can fully meet the construction technical requirements, adjust to a suitable capacity, and avoid the bolts from being too tight or too loose. If the torque value used in the construction process is insufficient, it will cause the bolt bearing capacity to decrease, and it will loosen immediately after a period of use, or can not be tightened at all. If the torque value used in the construction process is too large, the bolt will be over-tightened and overload operation will occur. , If the time is too long, it will break or even break during the tightening process. Therefore, the error of the torque value of the torque wrench should be controlled within ±5%. If the working condition requires higher, higher accuracy is required.
