Drill screw heads out. Remove tracks. Use vice grips or similar locking pliers to bite down on threaded shafts and spin em out. Or use a grinder to cut a larger groove into the screw head and use a big flathead or cut a large cross into the top and use and no 3 philips screwdriver to remove them.
If the screws are pan heads you might be able tilo bite onto the lip with a pair of locking pliers and forgo tge grinding/drilling/etc.
Yeah but these arent broken, just stuck. At least not judging by included photo they arent.
Extractors have a time and place but theyre more of a last resort than a first line IMO. These screws just appear to be in wood so OP just needs more leverage frankly, hence the suggestion of a larger slot which will allow a no 3 philips or a 5/16 or 3/8 flathead to get more bite.
