How to Remove a Stripped Screw: A Comprehensive Guide
Dealing with a stripped screw can be incredibly frustrating, especially when you're working on a crucial project. Whether it's a tiny screw on your eyeglasses or a larger one on a piece of furniture, a stripped screw head can bring your work to a screeching halt. But don't despair! This guide will walk you through several effective methods to remove those stubborn stripped screws, saving you time, money, and frustration.
Understanding Why Screws Strip
Before diving into removal techniques, it's helpful to understand why screws strip in the first place. Common causes include:
- Over-tightening: Applying excessive force during installation is a major culprit.
- Incorrect screwdriver: Using the wrong size or type of screwdriver can damage the screw head. A mismatched screwdriver can easily cam out or slip, stripping the head.
- Corrosion: Rust and corrosion weaken the screw head, making it more susceptible to stripping.
- Low-quality screws: Cheaper screws are often made of softer materials, making them more prone to damage.
- Impact force: Repeated impacts, such as from hammering, can weaken the screw head.
Methods to Remove a Stripped Screw
Now, let's tackle the problem at hand – removing that pesky stripped screw. We'll explore several techniques, from simple to more advanced.
1. Rubber Band Trick:
This surprisingly effective method works well for slightly stripped screws. Simply place a rubber band over the stripped screw head before inserting your screwdriver. The rubber band provides extra grip, improving the screwdriver's purchase.
2. Using a Grip-Improving Tool:
Several tools are designed specifically for removing stripped screws. These include:
- Screw Extractor Set: These sets contain specialized bits with reverse-threaded tips that grip into the stripped screw head, allowing you to unscrew it.
- E-Z Out Screw Extractor: Similar to a screw extractor set, but often considered more robust for challenging situations.
- Impact Driver: An impact driver delivers forceful, controlled rotational blows, which can often break loose a stubborn stripped screw.
Remember to choose the right size extractor or bit for your stripped screw.
3. Drilling Out the Screw:
This is a more destructive method but often necessary for severely stripped screws. You'll need a drill with a drill bit slightly smaller than the screw's core diameter. Carefully drill into the center of the screw head until you reach the shank. Then, use a screw extractor or a flat-head screwdriver to remove the remaining screw. Caution: Be extremely careful not to drill too deeply and damage the underlying material.
4. Using a Vice Grip or Pliers:
For screws with larger, relatively flat heads, you might be able to use pliers or vice grips to grab the screw head and twist it out. This method requires careful application to avoid damaging the surrounding material.
5. Penetrating Oil:
If the screw is rusted or stuck, applying a penetrating oil (like WD-40 or PB Blaster) can help loosen it. Allow the oil to penetrate for several hours or even overnight before attempting removal.
Preventing Stripped Screws
Preventing stripped screws is always better than having to remove them. Here are some preventative measures:
- Use the correct screwdriver: Always use the right size and type of screwdriver for the screw.
- Don't over-tighten: Apply only the necessary force to secure the screw.
- Keep your tools in good condition: Damaged or worn-out screwdrivers can easily strip screws.
- Use high-quality screws: Investing in good quality screws is a worthwhile investment.
By following these tips and techniques, you can conquer even the most stubborn stripped screws. Remember to always prioritize safety and choose the appropriate method based on the severity of the stripping and the material you are working with.
