Grades of Bolts - The Home Depot

There are several grades of bolts but the three common grades for SAE are 2, 5 and 8. The common class (grades) for metric are 5.8, 8.8, 10.9 and 12.9. Each grade has a specific bolt strength. No matter the system used to grade the bolts, the higher the number means the stronger the bolt.

Jan 08, 1993 · The first number of the bolt class corresponds to the ultimate strength e.g. 400 MPa for classes 4.x, 500 MPa for classes 5.x, 600 MPa for classes 6.x, 800 High-Strength Gr. 8.8 Gr.10.9, Gr.12.9 ASTM A325,A490 High-Strength Gr. 8.8 Gr.10.9, Gr.12.9 ASTM A325,A490 Heavy Hex Bolt Heavy hex structural bolts are designed for steel-to-steel structural connections. Consequently, they are typically very short. The A325 and A490 specifications are not intended for general applications, including anchor bolts.
