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.

Good Afternoon Sir, I received your letter in the mail today. I was ecstatic to receive and read it. It was wonderful doing business with you and your company. The first initial response was great, they got my order in pronto. Even after my mistake of ordering the wrong size of bolts, they were very accommodating and understanding and worked with me to get the right ones ordered. I will definitely keep you and your company in mind when someone is needing your line of product. I appreciate and thank you for all your help. P.s. Thank you for the glasses clothe, with having a 5 almost 6 year old my phone is in need of constant cleaning. It will be well used.

– W.
