Some more suggestions I found...this one involves something like super glue..of course if I recall the darn screws are really tiny...
Use JB Weld or equivalently super strong “welding” adhesive to attach a nut to the screw head. Pick a nut that is about the same size as the screw head or at the least such that the diameter of the hole in the middle of the nut is smaller than the diameter of the hole in the screw. Now place the nut centered on top of the screw. Fill the hole with JB weld, being careful to not let it run everywhere. If the nut is flush on the screw, this shouldn’t be a problem. If it can’t be flush, use some sort of quick drying temporary gasket or the like to seal around the edges so that the JB weld doesn’t get everywhere, but rather just stays in the hole. Now let it dry the recommended time. Once it has hardened up, use a socket wrench on the attached nut to remove the screw.
