How to remove bolts with rounded off hex heads?

  • I brok my fly wheel and manage to get three of the SIX bolts that connect the flywheel to the crank shaft. I have three that have the heads rounded off from rubbing on the flexplate. I tried undersized sockets 12 pt. 6 pt and even one of those gadgets that grip rounded off bolts and no joy there either. should I try heat, grind off the heads, grind a flat spot to grab, Vice grips aren't even stron enough. I tried an inpact hammer, nothing. I do no want to take out the crank. It was a 14mm head. can I hammer on a 13mm or not. ITs a GMC 1989 S15. all thats left attached of the flywheel is a ringabout the size of a glazed donut. Help before I kill myself trying.

  • Answer:

    Those are the most frustrating repairs... I've never had any luck with stud removers. After all, if the bolt wasn't frozen, I wouldn't have broken the head or rounded it off in the first place. $1 says that you'll end up breaking the bolt, and having to drill it out and retap it.

Go to a local auto parts store and purchase a stud remover - this is a small tool that grips a rounded shaft and attaches to a ratchet - the harder you turn the ratchet, the tighter it grips the bolts.

try grinding both sides to fit a wrench try for 12 mm go slow and only take a little off at a time so the wrench fits tight would also give vise grips better bite
