I am changing my old rusted garden gate with a new one. However, because of a couple of rusted screws, I could not remove the gate-post attached to the walls on either end of the old gate.
I tried applying WD-40 lubricant to loosen the screw so I could unscrew them using a screwdriver, but I hadn’t had very much luck with that. Later I tried lightly striking the gate-post with a hammer, hoping to loosen it from the wall, but that didn’t work either.
Is there another approach I can take to remove a rusted screw from the wall?
