How To Take Out A Broken Screw Head

How to Remove a Stripped Screw Head: A Comprehensive Guide

Removing a stripped screw head can be incredibly frustrating, but with the right tools and techniques, it's entirely manageable. This guide will walk you through various methods, from simple fixes to more advanced techniques, ensuring you can conquer even the most stubborn stripped screw. Whether it's a stripped screw in your furniture, electronics, or car, this guide has you covered.

Understanding the Problem: Why Screws Strip

Before diving into solutions, let's understand why screws strip in the first place. Over-tightening, using the wrong size screwdriver, using a damaged screwdriver, or corrosion are all common culprits. A stripped screw head presents a smooth, unusable surface, making it impossible to grip with a standard screwdriver.

Methods for Removing Stripped Screw Heads

Here are several methods, ranging from easiest to more advanced, to tackle that pesky stripped screw:

1. Using a Grip-Enhancing Tool:

• Rubber Band: Place a rubber band over the stripped screw head before inserting your screwdriver. The added grip can provide enough traction to remove the screw. This is a simple, low-cost solution for minor stripping.
• Screw Extractor: These specialized tools have reverse-threaded bits that bite into the stripped screw, allowing you to easily unscrew it. They are readily available at most hardware stores. Choose the correct size for your screw.
• Grip-Enhanced Screwdriver Bits: These bits have stronger gripping power, often incorporating magnets or special materials to provide a more secure hold on stripped screws. They're a good investment for frequent DIY projects.

2. Drilling Out the Screw:

This method is more involved and requires precision, but it's effective for stubborn screws.

• Use a Drill Bit Slightly Smaller Than the Screw: Carefully drill a pilot hole into the center of the stripped screw. Avoid applying too much pressure to prevent damage to the surrounding material.
• Use a Screw Extractor (again): Once the pilot hole is created, use a screw extractor to remove the remaining screw.
• Alternative: Use a Left-Handed Drill Bit: This method can sometimes work if you have a left-handed drill bit slightly smaller than the screw diameter. It will reverse the screw as you drill.

3. Using Heat:

Applying heat can sometimes expand the metal surrounding the screw, making it easier to remove. Use a heat gun or soldering iron (carefully!), focusing the heat on the screw head. Let it cool slightly before attempting removal. Caution: This method is not suitable for all materials, particularly plastics or wood that could be damaged by heat.

4. Penetrating Oil:

If the screw is stuck due to corrosion, applying a penetrating oil like WD-40 can help loosen it. Allow the oil to soak in for several hours or even overnight before attempting removal. This softens the corrosion, making the screw easier to turn.

Preventing Stripped Screws:

Preventing stripped screws is crucial. Here are some helpful tips:

• Use the Correct Screwdriver: Always use a screwdriver that precisely matches the screw head type and size.
• Avoid Over-Tightening: Tighten screws firmly but avoid excessive force.
• Lubricate: Using a lubricant before installing screws can help prevent them from becoming stuck or stripped.
• Maintain Your Tools: Ensure your screwdrivers are in good condition, without any damage or wear.

Conclusion:

Removing stripped screws doesn't have to be a major headache. By following these methods and employing preventative measures, you can tackle this common DIY challenge with confidence. Remember to choose the method that best suits your situation and always prioritize safety. With a little patience and the right tools, you'll have that stubborn screw out in no time!
