What causes a bolt to be pulled off

Pull off the bolt

First spray everything well with rust remover . Then unscrew the locking plate. Use the grinding wheel to grind the protruding part of the bolt. If the bolt drifts backward, weld a thinner bolt onto the protruding end and use the sledgehammer to knock the thing out.
If the bolt only goes out, get a suitable threaded rod and try a hammer puller. Or with a hydraulic extractor. Or make yourself a device where you can attach a hydraulic ram (jack).

It is always written that everything should be treated with rust remover, etc.
I've never seen the stuff solve anything as promised.
So far, brute force, the fire crowbar and or something new have mostly helped.
For me, roast remover is only good as a short-term lubricant for better slipping or to quickly get something more agile.

let's call that stuff creeping oil ... It works, but mostly not for a short time or quickly. I use it the day before to give it a chance. Of course, it only works to a limited extent, if at all, to loosen rust, it only reduces the sliding resistance. If you are close to loosening the screw connection, then that could be the missing 5%. If you can't, you can still be brutal.

It's nice that others see it that way too. Faith also plays a very important role.
The least stuff is by far WD-40, which is only good for lubricating and cleaning.
The vile caramba or temperature difference is still best.
But I would first cut the thread so that the threaded rod can be screwed in cleanly.
Then as already described, or a correspondingly thick material over the threaded rod, nut on it, support on both sides to warm the bolt around and pull it out with the nut.

Thank you thank you thank you!
So if I am not alone, although "everyone" swears by spraying, a screw connection does not want to loosen immediately.

My observation is: If you have a rusted screw with a nut and spray it with WD40, Caramba or whatever and then let it work for a day before you unscrew it, you can see that the stuff doesn't really penetrate the thread.
To reduce the sliding friction or to rinse dirt / rust particles out of the thread, make ne stiff mechanics passable, yes.

And on the subject:
If you are working with a threaded rod, make sure that it is not a 0815 rod from the hardware store, because of the quality, they usually only have 4.8?
If you prefer to get it in 10.9 / 12.9.

So now the topic of rust remover, WD 40 and what I don't know what else, has been talked about more or less extensively . Unfortunately, this does not help the treath creator. Rust remover or not. If everything is sprayed well with rust remover or penetrating oil and the bolt starts to move in whatever way, there is a possibility that the broth that was previously sprayed on it reduces the frictional resistance and therefore makes little sense . And that's why I use this kind of stuff in actions like this. Because badly lubricated is still better than not lubricated at all .

The rust removers need to take effect, preferably several days and spray again and again. Then they also show an effect. Spray on and after 5 minutes unscrew it will not work.

But if I have to turn a nut over a protruding, heavily rusted thread and spray it beforehand with roasting solvent, penetrating oil or WD 40, this helps a lot and makes my work easier. So it always depends on the respective purpose. And if all this stuff was really that pointless, people wouldn't buy it by the box. By the way, my personal favorite is Ballistol.

In the "almost impossible" case, it helps such a bolt, if it is at all feasible, to loosen it by striking each other. But please do not hit the bolt directly with a hammer (because of mushrooming), if feasible put on a round steel bar and hit it.
Sometimes it can "seize up" due to one-sided knocking out. And yes, rust remover can be helpful as a lubricant.
I would probably take the burner around the bolt (not directly heat the bolt) and then it has to be done quickly before the bolt has absorbed all the heat.

But that would be the very brave version
The first choice of approach is the one in the 1 post by @ferguson-power and then it can gradually get more complicated.

There's a thread in there, if that's still something I would try with the hammer puller

times ne stupid question .. here is already a lot of advice or not .. but what is on the other side of the bolt? what is he holding on at all? - does it have to go to the photographed side or is there a plate on the other side? should it remain intact or may it be killed?
