broken bolt help

Y'all need to try the welding the nut to the bolt trick, works every time. No need to drill and retap the hole. Doesn't matter how bad the bolt is stuck. When you weld the nut to the bolt, it heats it up, free's the threads and it'll come right out if you immediately put a wrench to it.

Been there, done that. at least a handfull of times. You're right heat helps. I'm pretty carefull not to apply too much torque and break off a fastener, but when the threads are seized so badly that the head will twist off, an EZ out cannot apply more torque gripping inside the fastener than the entire thickness of the fastener will support.

I still try an EZ out every time, but it has never worked for me in that situation. Helicoil and/or retapping works.
