I graduated from tapping the stud with a hammer to a solid whack from the top. The stud popped right out. I took the broken stud to Fastenal and they said they had no such animal. I got a carriage bolt and ground the square protrusion from the underside of the head of the bolt with my dremel so it would fit in the hole better. The problem I had was that there was nothing to keep the carriage bolt from turning when I tried to tighten the nut. I gave up on the carriage bolt and got a cap head screw so I could use a hex wrench to keep the screw from turning when tightening the bolt. That worked just fine. I looked at the torque wrench and said to myself "not again" and tightened by feel. Looks like I am good to go again.
