Grade 8 Medium carbon alloy steel, quenched and tempered: 1/4" thru 1-1/2" 120,000: 130,000: 150,000: Grade A325 Carbon or alloy steel with or without boron: 1/2" thru 1-1/2" 85,000: 92,000: 120,000: Stainless Markings Vary: 18-8 & 316 Stainless Steel alloy with chromium and nickel: All sizes thru 1" N/A: 20,000 Min. 65,000 Typical For example, if a bolt has a nominal tensile strength equal to 500 MPa and a yield strength ratio of 0.8, its metric bolt grade is 5.8. If the same bolt has a reduced loadability, it can be designated by 05.8. In general, metric bolts are available in grades 4.6, 4.8, 5.8, 8.8, 9.8, 10.9, and 12.9.

Yield Strength Of A Grade 8 BoltIf the grading is 8.8, with reference to the first number 8, this means the ultimate tensile strength (breaking strain to be at least this) is 800MPa, or, 800N/mm². With reference to the second number, multiplied by 10, gives the percentage of the first calculation to provide the Yield Strength. How Strong Are Grade 8 Bolts Grade 8 bolts are the highest grade of bolts under the SAE J429 standard which means they have the highest strength Here are their various strength specifications

Grade 8 bolts are made of alloy steel and have a tensile strength of at least 150,000 PSI. Alloy steel bolts are very strong and are used in demanding applications such as in automobiles and industrial machinery. Three Systems of Bolt Grades. There are three main systems of bolt grades: SAE, ASTM, and ISO. SAE (Society of Automotive Engineers .
