Select the appropriate hex bolt
Before using hexagonal bolts, you must first select the appropriate bolts. According to different applications, bolts with different specifications, strength grades and materials need to be selected. When selecting bolts, pay attention to the degree of compliance with relevant standards to avoid accidents.
Check the surface and quality of bolts
After selecting the hexagonal bolts, check whether the bolt surface is smooth, free of rust, scratches, etc. If you find a problem, you can choose to replace the bolt or repair it. In addition, the quality, strength grade, etc. of the bolts should be checked to ensure that they can withstand the load.
Use the correct wrench or wrench head to tighten
When using hex bolts, it is necessary to use an appropriate wrench or wrench head for tightening. Bolts of different types and specifications need to use corresponding wrenches or wrench heads to ensure that the tightening force meets the requirements.
to be uniform
When tightening the hex bolts, attention must be paid to the uniformity of the degree. If the tightening force is insufficient, problems such as loosening are prone to occur; while over-tightening will cause the bolt strength to decrease or even break. Therefore, appropriate and uniform strength should be used when tightening.
Pay attention to the extrusion force of the bolts
In some cases, hex bolts may be subjected to crushing forces. In this case, the bolt's load-carrying capacity changes and it may lose strength. Therefore, in this case, special attention should be paid to the selection and use of bolts.
