Mine is an allen head bolt. Is it stripped out where an allen wrench would
go in? Those are pretty hard to strip.

Maybe you can hammer a big torque bit into it.

5/16 bolt stripped by last owner. Any ideas how
to get it out.

Thanks

If you mean that the head is rounded off, as opposed to the threads
being stripped, Craftsman makes a set of sockets that work on rounded
heads.
