Expansion bolt

Expansion bolt is a special threaded connector used to fix pipe supports/hangers/brackets or equipment on walls, floors and columns. The grades of carbon steel bolts are divided into more than 10 grades, including 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9 and 12.9.

The numbers before and after the decimal point respectively represent the nominal tensile strength and yield ratio of the bolt material. For example, if a bolt with grade 8.8 is marked, the tensile strength of the material reaches 800MPa, and the yield ratio is 0.8, that is, the yield strength reaches 800x0.8=640MPa.
