I know it's a little off topic, but hoping someone here has similar experience and could offer some advice. The door glass on my pellet stove was cracked so I had new pane cut at a local fireplace shop. He told me to bring the door in so he could get an exact measurement, and when I get there with the door I'm told they don't take old glass out. I now know why. I picked up the new glass today, he even threw in a gasket. The old glass is held in by four metal clips that are bolted to the door. The top two came out no problem but the bottom two are seemingly permanently part of the door, thanks to years of heat I assume. I tried a Gator Grip socket since i still had some edge on one side of head, useless piece of crap excuse of a tool only seemed to round off the edges even more and stripped the straight edges that I once had. I tried wd40 let it soak in then heated with propane torch, no help. All I've managed to do is back one off at most 1/4 turn, in doing that the edges on the head are all rounded. The other bolt still has some edges so I'm afraid to do anything with that. Any advice, comments, criticism?
