Bolt performance level 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9 and other 10 grades;
Among them, 8.8 and above bolts made of low-carbon alloy steel or medium-carbon steel and heat treatment (quenching, tempering), collectively referred to as high-strength bolts, and the rest collectively referred to as ordinary bolts.
Bolt performance level marking has two parts of the digital composition, respectively, that the nominal tensile strength of the bolt material value and flexural strength ratio value.
The meaning of 4.8 is
Tensile strength Rm=4×100 N/mm2=400 N/mm2=400MPa
Yield strength Re = 400 × 0.8 = 320MPa
