Need a Little Help Removing Old Vise Jaws

I'm trying to get the screws out of the old vise jaws. I managed to get them to turn a little, but only about half a turn or so. Any suggestions for getting them out? Should I just drill them out, and assume that they are somehow bent?

Drill'em out... or

Have you considered the old "weld a nut to the flat head screw trick" ?

You could try some kind of penetrating oil like PB Blaster.

Sine they move I would put the tightest tip I could fit in in my batt powered drill on a super low clutch setting and rock it back and forth oiling the shit out of it and slowly increasing the clutch settings. It I got to the highest clutch setting without stripping the head I would go to my smallest impact driver and continue. Id work my way up my impact drivers until I stripped the head or got it out. Once I stripped the head I would weld a nut on it and go back to work with the impact gun. EZ out would be my last resort

This. EZ out is never as easy as you hope it to be and you often end up ruining the threads if you just go to drilling.

The head is probably deformed, causing it to get traction on the serrated jaw itself. You could probably torch out the head and remove what is left of the bolt with a pair of vise-grips or fingers.

I also like this idea! Get a tip that fits well in the screw head.

I've used those tools a lot on older Japanese motorcycles that always have small diameter, steel, Phillips head or flat head machine bolts screwed into aluminum.
