I just bought new egg beater pedals. Before them I had some cheapo nashbar pedals that I had some trouble with, one screw kept coming out and then I was stuck in the pedal for quite some time (it wasn't funny then). So I bought some longer screws and really tightened them down. Now I can't get that screw out. I drilled the head of the screw and pried off the cleat off thinking that I'll cut the screw off and put the new cleats in the other holes. After that ordeal, I found out that I can't fit a hacksaw to cut the screw off. Any suggestions?
