I've removed a hundred security bars from arcade games and every single one of them was affixed with a nut or nuts. This thing is like a screw with some kind of clamp going into the wood and the screw itself had a pin sticking through it. I removed the pin but still can't get the screw out. I've taken a hammer, bolt cutters, and anything else available to it. I'm about to jump through a tempered glass window. I mean seriously? I've got plenty of electronic and art-related stuff to deal with but I can't get the freakin security bar off?

from the inside of the cab the mount looks like the type sometimes used in cabs to mount leg levelers. It also looks as if the back of the bolt is slotted and a screw driver may be able to turn it from that end. Outside of the cab looks like a flat head bolt which I'd imagine if long enough could have been finger tightened to get to the point where the screw driver could be used from the back side. Basically looks like someone using parts on hand to get a job done. Either that or a strange security design that didn't last the test of time.
 
Use a flat bladed screwdriver to turn that slotted bolt forward through the t-nut once the retaining pin is removed (which you mentioned you'd already done).

If that doesn't work. Get out an angle grinder and grind the head off that bolt. Then you can push it through to the inside of the cab and the T-nut should come with it.

I completly removed mine from my TMNT cab because they were all scuffed up.. Then I bondoed the holes and installed new leg levelers..
 
well I unscrewed it most of the way but towards the end it got stuck *and* the piece with the teeth came out of the wood so no leverage so basically back to square one and off to home depot to spend some money on something to cut through the *#($* thing
