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;
4.8 means
Tensile strength Rm=4×100 N/mm2=400 N/mm2=400MPa
Yield strength Re=400×0.8=320MPa
8.8 means:
The first 8 on behalf of the tensile strength Rm
Rm = 8 × 100 N/mm2 = 800 N/mm2 = 800MPa
The second, .8 for the yield strength of the ratio of 0.8
Re800 * 0.8 = 640MPa
8.8 and 4.8 is the strength of the bolt is a different level of general 8.8 level of bolts with 45 steel, 4.8 level with Q235-A
