After a few hours of fighting with them, you kind of lose hope, and walk away. That's what I did, but I'd go back a few minutes later all pissed and hyped up thinking, "A bolt is not going to beat me."
And eventually, the socket and extensions just happen to find the perfect position to slide on and then it's cake. Oddly though, I broke both the 13mm bolts lose with the 1/4 inch drive.
