Grade 5 Bolts and fasteners are made of medium strength carbon steel and are specified under the Society of Automotive Engineers (SAE). If your application calls for heavier materials, you may need Grade 8 Bolts because they are the hardest and are often used in heavy manufacturing applications. Otherwise, Grade 5 bolts can be used. These bolts are heat treated in a controlled atmosphere from 1⁄4 in. through 1-1/2 in. with a minimum tensile strength of 120,000 psi in diameters through 1 in. and 105,000 psi for diameters over 1 in. through 1-1/2 in.
