You could try a locking jaw pliers and if that doesn't work get a cold chisel and make a little dent straight in the side of the bolt, then use the chisel at an angle and hammer it counterclockwise and it should loosen.

But the lock jaw pliers,(vice grips) should work.

 

but one of those alligator sockets!
