Hexagon bolt is a fastener composed of finger part and screw. The bolts are divided into iron bolts and stainless steel bolts according to the material, that is, hexagon bolts (partly threaded)-C and hexagon bolts (full threaded)-C, also known as hexagon bolts (rough) hairy hexagon bolts and black iron screws.
Hexagon bolt: A type of fastener consisting of two parts, head and screw (cylinder with external thread), used in conjunction with a nut to fasten two parts with a through hole.
This type of connection is called bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.
This type of connection is called bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.
Bolts for steel structure connection are classified into more than 10 grades, such as 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9 and so on. The bolts of 8.8 grade and above are made of low carbon alloy steel or medium carbon steel and have been heat treated (quenching, tempering), which are generally called high strength bolts, and the rest are generally called ordinary bolts. The bolt performance grade label consists of two parts, which represent the nominal tensile strength value and the flexure ratio of the bolt material respectively.
The meaning of bolt performance grade is the international standard, the same performance grade of bolts, regardless of the difference in material and origin, its performance is the same, the design can only choose the performance grade.
The strength grades called Class 8.8 and 10.9 refer to the shear stress grades of the bolts of 8.8GPa and 10.9GPa.
