So, you've got a stripped screw. It's a frustratingly common problem, whether you're working on a delicate piece of electronics or tackling a stubborn piece of furniture. But don't despair! This guide will equip you with the tools and techniques to remove those pesky stripped screws, minimizing damage and restoring your project to order.
Understanding the Problem: Why Screws Strip
Before diving into solutions, it's helpful to understand why screws strip in the first place. Several factors contribute:
- Over-tightening: This is the most common culprit. Applying excessive force when tightening a screw can easily damage the screw head and the surrounding material.
- Incorrect Screwdriver: Using the wrong size or type of screwdriver (e.g., using a Phillips head screwdriver on a flathead screw) will almost certainly lead to stripping.
- Damaged Screw: A screw that's already slightly damaged or corroded is more susceptible to stripping.
- Material Weakness: Soft woods or plastics are more prone to screw head damage than harder materials like metal.
Methods to Remove Stripped Screws
Now for the good stuff – let's explore various techniques for removing those stubborn screws. We'll start with the simpler methods and progress to more advanced ones.
1. Rubber Band Trick:
This simple trick often works wonders for slightly stripped screws. Place a rubber band over the screw head before inserting your screwdriver. The rubber band increases friction, providing a better grip.
2. Increased Grip Methods:
- Applying Pressure: Sometimes, applying firm, even pressure with the correct screwdriver can help you regain enough grip to remove the screw.
- Using a Different Screwdriver: Try different screwdrivers – one might offer a slightly better fit than the one you initially tried. A higher quality screwdriver with a precise tip is crucial.
- Try a new bit: If you are using a power drill, ensure you're using the right bit with good grip.
3. Specialized Tools:
If the above methods fail, it's time to bring out the heavy artillery:
- Screw Extractor Set: These sets contain specialized bits designed to grip into stripped screw heads. They are incredibly effective, even on severely damaged screws. There are several types; choose one appropriate to your screw type and size.
- Easy-Out: Similar to a screw extractor, an Easy-Out is a specialized tool designed for removing stripped screws. Follow the instructions carefully, as incorrect use can damage the screw further.
- Dremel Tool (with caution!): A Dremel tool with a cutting bit can carefully create a new slot for a flathead screwdriver. This is a delicate operation and requires precision. Be cautious not to damage the surrounding material.
4. Drilling it Out:
As a last resort, you may need to drill out the screw. This requires care and precision. Center-punch the screw head and carefully drill a hole slightly smaller than the screw's core. This method usually destroys the screw and might require replacing the damaged material. This should only be done if other options are exhausted.
Preventing Stripped Screws: Proactive Measures
Preventing stripped screws is far easier than removing them. Here are some preventative measures:
- Use the Correct Screwdriver: Always match the screwdriver to the screw type and size.
- Apply Even Pressure: Avoid excessive force.
- Lubricate Screws: A little lubricant (like WD-40) can help prevent stripping, especially in hard-to-reach areas.
- Pilot Holes: When working with wood, always pre-drill pilot holes to prevent the wood from splitting and to guide the screw.
Conclusion
Stripped screws are a common frustration, but with the right tools and techniques, they are manageable. Remember to start with the simpler methods and progressively move to more advanced tools only when necessary. And most importantly, preventing stripped screws through careful work is always the best approach.
