Tools List for How to Remove Stripped Screws:
- Screwdriver
- Self-locking pliers
- Cordless drill
- Screw extractor
Steps for How to Remove Stripped Screws:
1. Try removing the stripped screw with the proper size manual screwdriver.
2. If the screw head is protruding from the surface, grip it with self-locking pliers and twist out the screw.
3. Use a cordless drill, set in reverse, and left-handed bit to drill a small hole into the head of the stripped screw.
4. With the drill still set in reverse, use a screw extractor to back out the screw.
5. If the screw head has snapped off, use a hollow-boring screw extractor to drill out the entire screw. Fill the resulting hole with a tapered wood plug.
