Evil scumbag chainring bolts!

I just bought a big screwdriver (which still wasn’t big enough so I’ll take it back) to remove the last stinkin’ bolt from the GT SS chainring. It was done up pretty tight and nothing I had would fit in the slot properly and allow enough resistance to undo the allen bolt on the outside..

I was at the stage where I was going to drill the little bastard out and just buy a new one but then remembered I had some multigrips. Clamped down on the female piece, crossed my eyeballs (my fingers were busy) and spun the allen key.. WOO! It worked! So now I can contine with the driveline swap.. although I’ll probably need a new chainring bolt anyway.. stupid things..
