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.

March 7, 2016, 4:06pm Let me put it this way: January started my 37th year in this business, (I’ll be 55 in June, so I started when I got out of high school). Nobody ever calls when you go over and above and get them out of a bind. You can fill 99 out of 100 items, and they will call and bitch about that one item. Very seldom do they let you know how you got them out of a bind., or did the extra for them, or stayed late or delivered stuff on the weekends, etc. They have come to take it for granted, but I suppose we created the monster by the service level we maintain. And service is what we have that the big guys do not. John Wilson, there at U-Bolt It, did a fantastic job for us. I figure the sizes and quantities we were requesting were a little of a shocker, but John was all over it. And we appreciate all that he did. All of these SS U-Bolts were for our nuclear plant here in Mississippi. They went on re-fuel outage a couple of weeks ago, which they do every two years. And when they go on an outage, it is wide open for about a month. Cost doesn’t matter, freight doesn’t matter, get it here, and get it here fast. I’ve been through about 10 of these outages, and they never plan ahead very well. So compliments are in order for John and whoever else there did these for us. U-Bolt It did an exceptional job and we do appreciate it. Anything else comes up like this, you will be the first on the list. Let me add this though…..I’m not totally convinced that John went out in the plant and got his hands dirty….just saying
