Removing a damaged screw can be frustrating, but with the right techniques and tools, it's entirely manageable. This guide covers various methods for tackling stripped, rounded, or otherwise damaged screws, from simple fixes to more advanced solutions.
Assessing the Damage
Before you begin, carefully assess the screw's condition. This will determine the best approach.
- Slightly Stripped: If the screw head shows minor damage, you might be able to salvage it with a simple method.
- Severely Stripped: Significant damage requires more robust techniques.
- Broken Screw: A broken screw embedded in the material demands a different approach entirely.
- Material Type: The material the screw is in (wood, metal, plastic) will influence your tool choice.
Tools You Might Need
Gather the necessary tools before you start. Having them readily available saves time and frustration. You may need some or all of these:
- Screwdriver (correct size and type): Start with the appropriate screwdriver. A good fit is crucial.
- Rubber Band: A simple rubber band can surprisingly improve grip.
- Pliers (needle-nose or slip-joint): For added leverage.
- Hammer: For gently tapping tools into place.
- Drill: For more stubborn screws or if you need to remove the screw head.
- Drill Bits: Appropriate size drill bits for drilling out the screw or creating a pilot hole.
- Screw Extractor Set: A specialized set of tools for removing broken or stripped screws. These are invaluable for difficult cases.
- Penetrating Oil (e.g., WD-40): To loosen rusted or seized screws.
Techniques for Removing Damaged Screws
Here are several methods, progressing from simplest to more advanced:
Method 1: Improved Grip
- Rubber Band Trick: Place a rubber band over the screw head. This increases friction and can provide the grip needed to turn the screw.
Method 2: Applying Leverage
- Pliers: Carefully use pliers to grip the screw head and turn it counter-clockwise. Use caution to avoid damaging the surrounding material.
Method 3: Penetrating Oil
- Loosen Seized Screws: Apply penetrating oil to the screw and let it sit for at least 15 minutes (or longer for particularly stubborn screws) to help loosen rust and corrosion. Try again with your screwdriver after applying the oil.
Method 4: Drilling Out the Screw
- For Stubborn Cases: If all else fails, you may need to drill out the screw. Start with a small pilot hole slightly off-center of the screw head to avoid damaging the surrounding area. Gradually increase the drill bit size until the screw head is removed or sufficiently weakened to be extracted with pliers or a screw extractor.
Method 5: Screw Extractor
- The Professional Approach: A screw extractor is a specialized tool designed for removing broken or stripped screws. Follow the manufacturer's instructions for proper use.
Preventing Damaged Screws in the Future
- Use the Correct Screwdriver: Always use the correct size and type of screwdriver for the job. A poorly fitting screwdriver is the most common cause of stripped screws.
- Apply Steady Pressure: Avoid forcing the screwdriver. Apply even, steady pressure when tightening or loosening screws.
- Lubricate: Applying a small amount of lubricant to the screw before installation can make future removal easier.
By carefully following these steps and selecting the appropriate method for your specific situation, you can successfully remove even the most stubborn damaged screws. Remember safety first! If you're unsure about any step, it's best to consult a professional.
