1.what are hex bolt?

Hexagon-head bolt is a commonly used screw in machinery, which has the advantages of easy fastening and disassembly, difficult sliding angle and so on.
4.Matters needing attention in installing external hexagon bolts.
1. When installing the external hexagon bolts, the force is uneven, and the force is too large when tightening the bolts. There is no corresponding wrench for each type of bolt to tighten, so the bolt does not reach the best condition. Some people think that the tighter the bolt is, the better it will be, but this is not the case. If the force exceeds the bearing limit of the bolt material, the bolt will be deformed or even broken. (It is necessary to use a suitable wrench and appropriate strength to tighten the bolts)
