use the poll and comment below, I've broken 3 today, 2 were rusty 1 was brand new, maybe I'm just really strong because I wasn't even using a breaker bar or putting my body into it

HE-MAN!!!!!!!!!!!!!!11
I don't think that they are supposed to break like that. I could be wrong tho.

You're a moron. Anything will break if you pass its breaking point.

Was my craftsman ratchet supposed to break? No, but, well, I was using it as a breaker. So duh, of course it did.

What were you trying to use the bolt for and what spec were you torqueing it to?

It was a seat mounting bolt for a garden tractor. I was tightening it to uh me pulling on the ratchet torque, I was using a regular sized Craftsman ratchet, no breaker bar or torque wrench.

What sort of heavy duty is the garden tractor seeing that it needs the seat bolts tightened as hard as possible?
Is this one of those racing lawn tractors?

A Gravely 12 G Professional, almost as big as my Subaru!

Oh but I tweaked the throttle cable so I basically doubled the usable RPM range. I'm assuming the factory range was limited to the engine's peak power band or something sensable like that.

I wonder if we could put an EJ22 on it.

What diameter was the bolt?

5/16-18

I guess if I thought about and mentioned the size it'd all make sense.

The seat is at the local Gravely dealer getting new backets welded on the bottom. I wish I could weld.

Yeah... 5/16" grade 5 hardware is fairly weak, and if it's rusty all bets are off.

Learn to weld!

shame we don't have any shop classes anymore, I'd be all over that in a minute

Maybe see if there are metalworking classes at your local community college or something?

That's what I'm doing this summer. Twice a week in the evening.

Are grade 5 bolts supposed to break under manual pressure?
