   Jun 8, 2018 · However, as you can see in the following table, both tension and shear are higher in Grade 8 bolts over Grade 5 bolts; in fact over 21% higher in shear and 25% in tension. The same is true in metric when comparing 8.8 vs 10.9. To be fair, the higher the grade of bolt, the harder it becomes as rated by the rockwell scale.

   What is a property class 8 bolt?

   • The second number is 1/10th of the percentage of the part’s nominal yield strength compared to the part’s nominal tensile strength. So, in English, a Property Class 8.8 bolt is a bolt with a nominal tensile strength of 800 MPa and a nominal yield strength that is 80% of that nominal tensile strength, so 640 MPa.
