Grade 5 Bolts

Grade 5 Bolts

Have AQuestion

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.

Grade 5 Bolts are equivalent to Metric 8.8 bolts, so when finding the right bolt, be sure to match the grades on the bolts being used. Grade 5 bolts can often be identified by the 3 marks on the head.

Each Grade 5 bolt from U-Bolt-It are available zinc plated.

We are a jobshop and have purchased most of our u bolts from McMaster Carr due to time constraints involved with our orders. We are mostly a repair and maintenance of production line equipment company so next day or same day delivery is usually the case on our material purchases. I do appreciate your interest in recent orders which have been capably handled by John Junior. His response to questions involving changes or additions to our orders have been timely and solved our problems.
