Removing stripped screws can be incredibly frustrating, but with the right techniques and tools, you can often salvage the situation without causing further damage. This comprehensive guide will walk you through various methods, from simple tricks to more advanced techniques, to help you conquer those pesky stripped screws.
Understanding Why Screws Strip
Before diving into removal methods, it's helpful to understand why screws strip in the first place. This understanding will help you prevent future problems. Common causes include:
- Over-tightening: Applying excessive force during installation is a primary culprit.
- Damaged screw head: A damaged or worn screw head is more susceptible to stripping.
- Incorrect screwdriver: Using the wrong size or type of screwdriver is a frequent mistake. A poorly fitting screwdriver slips, damaging the screw head.
- Material degradation: Over time, materials can weaken, making screws more prone to stripping. This is particularly common with older screws and wood exposed to the elements.
- Corrosion: Rust and corrosion weaken the screw head and make it more likely to strip.
Simple Methods for Removing Stripped Screws
For mildly stripped screws, these techniques might suffice:
1. Rubber Band Trick
This surprisingly effective method involves placing a rubber band over the stripped screw head. The added grip from the rubber band can provide enough traction for your screwdriver to bite.
2. Increased Grip with Tape
Similar to the rubber band trick, wrapping a piece of strong tape (duct tape or electrical tape works well) around the screw head can improve your screwdriver's grip.
3. Using a Different Screwdriver
Sometimes, a slightly larger or smaller screwdriver (of the correct type) might offer a better fit in the damaged screw head. Experiment carefully!
Advanced Techniques for Stubborn Stripped Screws
If the simple methods fail, you'll need to employ more advanced techniques:
1. Screw Extractor
A screw extractor is a specialized tool designed specifically for removing stripped screws. These tools have reverse-threaded bits that grip the screw and allow you to back it out. They're available in various sizes and are a worthwhile investment for any DIY enthusiast.
2. Dremel Tool with a Cutting Bit
For extremely stubborn screws, a Dremel tool with a small cutting bit can create slots or a new head for a flathead screwdriver. This requires precision and care to avoid damaging the surrounding material.
3. Drilling Out the Screw
As a last resort, you can carefully drill out the stripped screw. This requires a drill bit slightly smaller than the screw shaft, and you must drill straight to avoid damaging surrounding materials. Once drilled out, you may be able to use pliers to remove the remaining screw.
4. Using a Hammer and Chisel (for larger screws)
For large screws in wood, carefully applying a chisel to the screw head and tapping it with a hammer might allow you to turn the screw. This method should be used with caution to avoid damaging the surrounding material.
Preventing Stripped Screws in the Future
Prevention is always better than cure. Here are some tips to avoid stripped screws in the future:
- Use the correct screwdriver: Always use a screwdriver that precisely matches the screw head type and size.
- Apply even pressure: Avoid over-tightening screws. Use just enough force to secure them.
- Lubricate the screw: Applying a small amount of lubricant (such as WD-40 or machine oil) can make screw installation and removal smoother.
- Inspect screws before use: Damaged screws should be replaced before installation.
By understanding the causes of stripped screws and mastering the techniques outlined above, you can successfully remove even the most stubborn screws and avoid future frustrations. Remember to choose the appropriate method based on the severity of the stripping and the surrounding material.
