Hexagon bolt is a fastener composed of finger and screw. According to the material of bolt, there are iron bolt and stainless steel bolt

The bolt connection of the main component of the building structure is generally made of high-strength bolt connection.

There are many names for bolts, and everyone may have different names. Some people call them screws, some people call them bolts, and some people call them fasteners. There are so many names, but they all mean the same thing. They're all bolts. Bolt is a general term for fasteners. Bolt is the use of the object's beveled circular rotation and friction of physics and mathematical principles, step by step fastening tools
According to the relevant standards, the performance grades of carbon steel and alloy steel bolts are 4.6, 8.8, 10.9, 12.9, etc., among which the bolts of grade 8.8 and above are made of low carbon alloy steel or medium carbon steel and subjected to heat treatment (quenching and tempering), which are generally called high strength bolts, and the others are generally called ordinary bolts

The quality of the hole fitted by the bolt directly affects the fastening effect. Therefore, the design and processing should be in strict accordance with the relevant standards
