Is it possible to snap a bolt/fastener through using too much torque when breaking it

Ok... it will either break loose... or break... Yes... seen it... witnessed it... done it.
It's why I own extractors, dremels, left handed drill bits... way of life.

I assume you mean breaking it loose. Sometimes if they are too corroded they will.

yes. excessive torque, in either direction, is a surefire way to break bolts and studs. how much it'll take is much less certain.

I've sheared brand new grade 8 bolts with an impact, so yes it is.

I have busted a few. Happens a lot on old exhaust systems but I recently had a couple of suspension arm mounting bolts give up. For some reason I call it "shearing" while if it breaks while installing I call it "torquing". Guess it depends on if it broke by stretching or twisting.

Yes. I hope for my exhaust flange bolts to come off easy, or snap off when I first start.
I hate it when I get almost to the end and then it breaks.

When using excessive torque, a fastener will stretch, snap or break, but sometimes the threads will strip first.
If replacing cultivator shovels or grader blades, I would rather over-torque the old nuts and break the bolts off, rather than trying to unscrew them. I prefer to use new hardware to assemble the new components.
That isn't the way I prefer to remove a head bolt
Over-torquing a bolt while assembling any project is not in Your best interest.

The main reason I got a Snap-on 24" Ratchet was to break bolts. Faster than a impact and cleaner than a cutting torch.
Bolts with corrosion from fertilizer, silage acid or manure will break off easy.

Hell I've ripped the corner off flanges on exhaust systems using a Milwaukee fuel hex impact taking out a/f sensors, rusty heat cycled exhaust is all ways a pita to work on. Nut never broke free from the stud and stud didn't want to move, guess the rusty flange was the weak link in that case.
Only thing worse is water pumps on some engines, those thing rot to hell and shear as soon as you turn them. If your shearing it from torque something is keeping it from moving. That's when the blue tip wrench becomes your friend.

Anything to do with your missing header flange stud???
Nope. I may end up taking the heads off but I've read that taking em off can be a pain

Ha! I think the OP has not wrenched much.
Taking bolts out?

I read somewhere on the internet that the cheaper tools can break off a bolt. The quality tools from the truck brands have a built in torque limiting feature that they bend or break before the bolt will.

They are Easy-Outs until they snap. Then they become Damn Near Impossible to Take Outs.

Last one I broke was a wheel stud that twisted off when I started a brake job on our old Grand Caravan. I hadn't noticed the jack legs at the tire place cross threaded the lug nut.

Tire guy was changing tires on my classic and they were LH thread but he did not want to hear from me before he went to change them.

Curious; But was He allowed to continue wrecking Your other studs?
Could You share the details of an interesting episode in dealing with a humanoid "Lugnut" ?

Never .... just get a longer cheater bar and keep applying force ... it will eventually unscrew[emoji849]
