There are lots of nice little special tools made for the job, but without spending a small fortune at your local Sears there are ways using just normal hand tools.

If the hex recess has been rounded, you'll probably find that you can tap in a slightly oversize tool - often you'll find that imperial tools will fit the 'gaps' in sizes between metrics for this purpose.  

If the next size up is just too big to go in, try drilling the recess slightly larger until you can just be tapped in, forcing itself to 'cut' the hex edges into the inside of the recess in the screw head.  

Alternatively, you can hacksaw/dremel a slot into the head and use a big flat blade screwdriver head to get it out.  

Those bolts aren't ridiculously tight (or shouldn't be) so that should be enough to get one out.

The problem is that the socket screw is recessed and because the "hex" hole is rounded, there's nothing to turn the screw. The torch might work if I can find a way to torque the screw.

I didn't even think about the screw being exposed on the inside. That might open up other options. darn this place is awesome.

I think so. I never took it off before. There's only one screw that I see, and it looks like a 5mm recessed socket screw. It also comes out on the other side, but just a small point.
