Expansion bolts 304 stainless steel burst bolts
Dimensions: M6-M16
Standard Designation: GB/T 22795-2008
Material Grade: 304 Stainless Steel
Tensile Strength: 700
Rockwell Hardness (HRC):450MPA
Standard number: GB /T 22795 (TG) - 2008
Expansion bolts are 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, 12.9, etc.
The numbers before and after the decimal point represent the nominal tensile strength and yield strength ratio of the bolt material, for example: the bolt marked with grade 8.8 means that the tensile strength of the material reaches 800MPa, and the yield strength ratio is 0.8, that is, its yield strength reaches 800x0.8=640MPa.
