The performance grades of bolts for steel structure connection are divided 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, among which bolts of grade 8.8 and above are made of low-carbon alloy steel or medium-carbon steel and are heat-treated (Quenching and tempering), commonly known as high-strength bolts, and the rest are commonly known as ordinary bolts. The bolt performance grade label consists of two numbers, which respectively indicate the nominal tensile strength value and the yield ratio of the bolt material. E.g: The meaning of bolts of performance class 4.6 is: 1. The nominal tensile strength of the bolt material reaches 400MPa; 2. The yield ratio of bolt material is 0.6; 3. The nominal yield strength of the bolt material reaches 400×0.6=240MPa Performance grade 10.9 grade high-strength bolts, after heat treatment, can reach: 1. The nominal tensile strength of bolt material reaches 1000MPa; 2. The yield ratio of bolt material is 0.9; 3. The nominal yield strength of the bolt material reaches 1000×0.9=900MPa The meaning of the bolt performance grade is the international standard. The bolts of the same performance grade have the same performance regardless of the difference in material and origin. Only the performance grade can be selected in the design. The so-called strength grades of 8.8 and 10.9 refer to the bolts’ shear stress resistance grades of 8.8GPa and 10.9GPa
