Stainless Steel Bolts

Stainless steel bolts refer to bolts made of stainless steel, including stainless steel SUS201 bolts, stainless steel SUS304 bolts, and stainless steel SUS316 bolts. The performance grade of stainless steel bolts 8.8 refers to the tensile strength limit of 800MPa and the yield limit of 640MPa.
The performance grades of stainless steel bolts are divided into 10 grades: from 3.6 to 12.9. The number before the decimal point represents 1/100 of the material’s tensile strength limit, and the number after the decimal point represents 10 times the ratio of the material’s yield limit to the tensile strength limit. The performance level of the nut is divided into 7 levels, from 4 to 12. The number roughly indicates 1/100 of the minimum stress that the stainless steel nut is guaranteed to withstand.
