Turn off power or water supply if working on electrical or plumbing fixtures for safety.
Inspect the screw to determine how badly it is stripped and choose the appropriate method.
Place a rubber band flat over the screw head to fill the gaps and improve grip.
Firmly press a flathead screwdriver into the rubber band and turn slowly counterclockwise.
If the screw slips, grip it with pliers and carefully turn to remove.
For stubborn screws, apply super glue to a wooden toothpick, then insert into the screw head and let dry.
Once the glue sets, try turning the screw with a screwdriver again.
If the screw remains stuck, use a screw extractor kit following the manufacturer's instructions.
Drill a small pilot hole into the screw head if necessary to help remove it.
Replace the screw with a new one if it cannot be removed or salvaged.
Ensure all tools are used with proper safety gear, including gloves and eye protection.
Double-check that the area is safe and the screw is fully removed or replaced.
