Removing a screw is an easy task, if it's intact. But a stripped screw, one with a worn head, makes the job frustrating and time-consuming. You can't insert a screwdriver into a worn head to remove the screw, so you must use a different tactic. Two good options are removing the screw's head or using a screw extractor.
Removing the Screw's Head
Step 1
Drill through the center of the screw's head using a drill bit that's a third its size. Drill to about 1/8 inch deep. The screw's head should come right off.

Step 2
Drill through the center using progressively larger bits, if the original bit doesn't work.
Step 3
Remove the item held in place by the screw. Grip the screw's shank with pliers and remove it by turning the pliers counterclockwise.
Screw Extractor
Step 1
Drill into the screw's head until you've reached 1/8 to 1/4 inch depth. Ensure your screw extractor, a device that has cutting threads running opposite a screw, has a diameter smaller than the screw's shank.
Step 2
Tap the screw extractor into the screw using a hammer. Grip the top of the screw extractor with pliers or a wrench.
Step 3
Rotate the pliers or wrench counterclockwise to remove the screw.
