My nut is rounded off.

Hire that thing from strokerscamps avatar to chew that sucker off. ha, ha.

Try some blaster or kroil, heat, and some vice grips?

Cut off wheel might be a good last alternative, or even tack weld a rod to the end of the nut to get it started.

You ante kidding lmao some of those faces is pretty bad,thanks for the tips.
