It often happens that a bolt or stud breaks when trying to unscrew them. Extractors, drills, chisels, etc. can come to the rescue. After the remnants of the bolt are finally “tortured” by these tools, a welding machine comes to the rescue!

Give time to cool the nut, this is how it should turn out
We try to break the bolt, if it does not give in - soak special fluids. The bolt went
The remaining bolts are unscrewed, you can screw a new one!
