Had to remove the hex plug from the aluminum propane tank. Although not a percussion instrument, I hit it on impact and subjected it to 1200 ft/lbs of torque. The cork still wouldn't come out...so I put the tank in a large vise and pulled it out with a 6 foot pressure pipe. The plug came out, the socket didn't break. I am deeply impressed. I can't believe how much effort it took to get this connector out.
