OEM PATTERN Lock Bolt Removal

Hi

I have problem. I cannot for the life of me get the lock bolt off. the pattern has been destroyed and rounded out.

Anyway I should go about getting this thing removed?

How big is it? How much clearance around the bolt? Got any pics?

I had to deal with a lot of stripped bolts this week, this worked for me: use a grinder to cut a head in the outside surface of the bolt. Even two sides is enough, then get a pipe wrench on it.

For clarity: make the round outside of the bolt into a square/hexagon/circle with two flat sides.

Somehow I don't think he will have enough space for a grinder...

Maybe try a left hand drill bit or screw extraction bit

a di grinder could work with a drill bit type grinder. take some time but eventually you could probably sheer the head off. The other thing already mentioned is the 12 point socket and hammer. lol

Take a dye grinder with a small bit to it and cut the ring off.
