Very often you can get the squared end to re-engage with the wood by hammering the domed end further into the wood. The only problem might be if the nut is badly rusted on it will simply start to turn again once any torque is applied. Worth a try along with a good dosing of easing oil on the nut, you will not be in a worse position if it does not work.


....and possibly in a _better_ position - to cut the bolt above the nut
and then drive it out
