FWIW, I didn't bolt this thing together and I am learning the hard (and most likely expensive) way. Again. LOL!
Think I'm gonna buy a cheapie 12 point box and grind it down and use a propane torch. If that fails, I'll cut it with the grinder.
...Try your best to break it loose with a 6 point. A 12 point will come in handy after its broke loose. If the corners are rounding you might use a 6 point like this instead. It uses the sides more than the corners.
