Another good source is here, providing English and Metric values, and pictures of the head-markings for different bolt grades. Properly torqued bolts will provide the maximum amount of clamping force under load. All grade 8 bolts have the same tensile strength per square inch. What is the yield strength of Grade 8 bolts? Grade 8 (SAE J429) is a medium carbon alloy steel with one of the highest tensile strengths available. With a minimum tensile strength of 150 ksi and a minimum yield of 130 ksi, Grade 8 has a higher tensile and yield strength than other steel grades such as Grade 5 and B7. Customer service | Thus, the larger the bolt, the stronger the tensile strength of the bolt. for inner bolts: d = p1/(3d0) - 1/4. BS449: Part 2 Bolt Grade 4.6 Grade 5 bolts offer more strength and corrosion resistance than the grade 2 bolts and tend to see more use even though they cost a bit more.
