Do not attempt.
Just because I'm a dumbass don't mean that you can be too.
So DON'T try any of this **** l do at home.
wahoo got me a sticky

I have an old chart which shows a "Supergrade" designation above Grade 8. Anyone know anything about it?
I also have some bolts with that designation, but don't know where they are at the moment. If I happen to get a chance to find them, I'll try to post a picture of the head.
The chart is the same one (it came with a torque wrench), but these pictures aren't mine; they were 'borrowed' from a similar discussion at this site:
http://www.corvette-guru.com/modules...=10354&forum=6
and to add, the supertanium bolt is manufacturers branded bolt..
Another good bolt chart.

I can't imagine tighten a bolt to over a thousand foot pounds. As shown in that craftsman bolt chart. Need a super long pipe
>Innovations are what i leave behind for History<
Imagine... back 1963... INCO...Copper Refinery... reverbatory furnances... held together by long tie rods tensioned by BIG NUTS - 2 feet in diameter.
Now imagine 11 laborers carrying on their shoulders a giant, shop-built, open-ended wrench - the 'handle' is a 5 inch diameter pipe 12 feet long - Hi Ho, Hi-ho, it's off to work we go!!
Next imagine those 11 guys jumping up and down (in unison) on that 12 ft pipe-handle to tighten or loosen those 2 ft diameter nuts!
Been there! Done that! They didn't give out T-shirts then.

I hear that airplane props to this day are still torqued that way. One wrench, one weighed out guy, measure from center and hang.
Got an old fastener you can't identify?
I spent hours in my endeavor to identify a few old relics . Here are some useful sites I bookmarked before finally giving up.
If'n ya can't find it here...punt.

I was in an auto manufacturing plant many years ago. Got a close look at a 1000 ton forging machine for making CV joints. The press cycled about 1/second, and it sounded like a heartbeat you could hear and feel in your feet, throughout most of the plant.
The progressive dies were held in place by large hex head cap screws, at least 1" in diameter. They replaced all the bolts every 6 months or so, because they couldn't torque them tight enough to meet the bolt manufacturer's torque spec. I don't remember the exact number but it was well north of 1000 ft*lbs. The problem wasn't torqueing the fasteners, but rather that they'd warp the steel dies and mounting plates enough to warp the forging cavities and the parts made by the equipment. So they left the bolts "loose". This would all some movement which would fatigue the bolts. After more than 6 months in service, the hex heads would start popping off the bolts. Some time prior to my visit one of the factory guys got clipped in the head when one of the bolt heads popped off. He was wearing a plastic bump cap; which saved him from having his head split open. That's what started the factory replacing the bolts every 6 months.

Once again. Ductile vs. Brittle. Has nothing to do with a duck on a floor eating peanut brittle.. On applications where a bolt catches hell ( leaf springs, shackles, heavy spring mounts, heat-manifolding), grade 5 is the go to.Why ye bleateth. Resitance to multi-directional flexing.
I like to think of Tensile ratings as torque-ability. Rod bolts, head bolts, blade holding bolts etc.
Right or wrong ? Not sure. A mechanical engineer who designed locomotive parts put it to me this way. 5160 steel at 60 rc. vs 5160 @ 50. One is a blade the other is a spring. Simple enough.

I had to break and torque nuts when repacking cylinders on my 44,000# excavator, made an adjustable wrench from 6"C, 2 pcs 3/4 plate and 2- 1" threaded rod in little time, required 2000ft-lb. When I did one in my smaller machine I had to borrow a torque multiplier b/c the cap screw was set in the piston cap, needed a socket not the Mongo wrench. Sometimes half the battle is holding other end from spinning. Cylinder shops have a lathe looking setup with a short arm wrench rotated by a small hydraulic cylinder -similar to a slack adjuster on a truck- that go to 12,000 ft-lb.
