How to remove very stuck stripped screws

screws

These things are caught in hard wood. I made the dumb mistake of not drilling pilot holes.

Rubber band trick failed
Screw drill and removal bit failed
JB welding a bolt worked for 2/5. Trying again, failed for the remaining three a third time.

Anything tougher to get these out? Any tricks to get more hold on the jb weld?

Locking pliers, which is the generic term for a class of product often called by the name of one registered trademark (Vise GripsĀ® - no particular endorsement implied, but some of the cheaper knock-offs are quite useless. I believe Mole GripsĀ® in the UK)

You need them clamped on hard enough that they actually bite into the screw head. With that presentation, you'll only get a fraction of a turn at a time. And depending on how hard they are stuck, you might break the screw (at which point you drill around the screw with a hollow bit and remove the wood plug and screw carcass together)
