Vice-Grips!!
the real US made ones, not chinese ones. You can usually get a really tight grab on the tnut with the front face of the vice-grips, it's better if you can grab them on the side of the pliers though (with the body of the pliers lying on the wall) but sometimes the tnut is too deeply embedded in the ply for this.
If you cant get any purchase at all, drive a screwdriver in under the tnut and bend up 2 sides and then lock the visegrips on.
This is the system I use most at The Lactic Factory when some of my less-aware guest setters crossthread the capscrews all the way in.
Otherwise Phil S' system of grinding the back off is a good option, or if you're really keen and have a few 10mm drill bits to wreck you could attempt to drill out the head of the capscrew from the hold. (have never had to do this yet).
Have tried the extra screws method and it failed dismally.

In summary - get yourself some Vice Grips, they are the ducks guts all round super tool - I'm surprised you've managed to live this long without them.
