How to Get a Stripped Screw Out: A Comprehensive Guide
Dealing with a stripped screw can be one of the most frustrating experiences for any DIY enthusiast or professional. A screw becomes stripped when the head is damaged, preventing a screwdriver from gripping it properly. This often happens due to excessive force, using the wrong size or type of screwdriver, or simply wear and tear. But don’t worry, a stripped screw doesn’t mean your project is doomed. This comprehensive guide will walk you through various methods on how to get a stripped screw out, ensuring you can complete your task without further damage or delay.
Understanding Stripped Screws
Before diving into the solutions, it’s essential to understand what causes a screw to strip in the first place. The most common culprit is applying too much torque, especially with power tools. The soft metal of the screw head can easily be deformed, rendering the grooves useless. Another reason is using a worn-out or ill-fitting screwdriver. A rounded or incorrect tip won’t grip the screw properly, leading to slippage and stripping. Finally, poor quality screws are more susceptible to stripping than their high-quality counterparts.
Essential Tools for Removing Stripped Screws
Having the right tools on hand can significantly increase your chances of successfully removing a stripped screw. Here’s a list of some essentials:
- Screwdriver Set: A variety of sizes and types (Phillips, flathead, Torx) is crucial.
- Rubber Band: A simple yet effective trick for improving grip.
- Steel Wool or Pot Scrubber: Similar to a rubber band, it can fill the gap and provide better traction.
- Screw Extractors: These specialized tools are designed specifically for removing stripped screws.
- Drill: For use with screw extractors or as a last resort.
- Pliers: For gripping the screw head if enough of it is exposed.
- Penetrating Oil: To loosen the screw if it’s stuck.
- Hammer: For gently tapping the screwdriver to improve grip.
Methods for Removing Stripped Screws
Now, let’s explore several techniques on how to get a stripped screw out. Start with the simplest methods and progress to more complex ones as needed.
The Rubber Band Trick
This is often the first and easiest method to try. Place a wide rubber band over the stripped screw head. Then, insert your screwdriver into the rubber band and attempt to turn the screw. The rubber band fills the gap between the screwdriver and the screw head, providing extra grip. This simple trick often works surprisingly well.
Using Steel Wool or a Pot Scrubber
Similar to the rubber band, a small piece of steel wool or a pot scrubber can be placed between the screwdriver and the screw head. The fine strands of metal or abrasive material create friction, allowing the screwdriver to grip the screw better. Apply firm, steady pressure while turning.
The Screwdriver and Hammer Technique
Sometimes, the screw is simply stuck in place. Gently tapping the screwdriver with a hammer can help to loosen it. Place the screwdriver tip firmly into the stripped screw head and tap the end of the screwdriver a few times. This can help the screwdriver seat better and break any corrosion or debris that’s holding the screw in place. Then, try turning the screw again.
Using a Screw Extractor
A screw extractor is a specialized tool designed specifically for removing stripped screws. This is often the most reliable way on how to get a stripped screw out. These tools usually come in sets with different sizes to accommodate various screw sizes. Here’s how to use one:
- Select the Correct Size: Choose a screw extractor that is slightly smaller than the stripped screw head.
- Drill a Pilot Hole (if necessary): Some screw extractors require you to drill a small pilot hole in the center of the stripped screw head. Follow the manufacturer’s instructions.
- Insert the Extractor: Place the extractor into the drilled hole (or directly into the stripped screw head if no drilling is required).
- Turn Counterclockwise: Apply firm pressure and turn the extractor counterclockwise. The extractor’s threads will bite into the screw head, and as you continue to turn, it will gradually unscrew the stripped screw.
Using Pliers or Locking Pliers
If enough of the screw head is exposed, you can try gripping it with pliers or locking pliers (also known as Vise-Grips). Clamp the pliers tightly onto the screw head and turn counterclockwise. This method is more effective if the screw is not deeply embedded.
Creating a New Slot with a Rotary Tool
If the screw head is not too badly damaged, you can use a rotary tool (like a Dremel) with a cutting wheel to create a new slot for a flathead screwdriver. Carefully cut a slot across the screw head, being careful not to damage the surrounding material. Once you have a clear slot, use a flathead screwdriver to turn the screw.
Applying Penetrating Oil
If the screw is stuck due to corrosion or rust, applying penetrating oil can help to loosen it. Spray a small amount of penetrating oil around the screw head and let it sit for several minutes (or even hours for heavily corroded screws). The oil will seep into the threads and help to break the bond. After letting the oil soak, try one of the other methods mentioned above.
Drilling Out the Screw Head (Last Resort)
If all other methods fail, you can resort to drilling out the screw head. This should be considered a last resort as it can damage the surrounding material. Use a drill bit that is slightly smaller than the screw’s shank (the smooth part of the screw below the head). Carefully drill into the center of the screw head until the head separates from the shank. Once the head is removed, you should be able to remove the remaining shank with pliers or by pushing it through. This method is a more destructive way on how to get a stripped screw out.
Preventing Stripped Screws in the Future
Prevention is always better than cure. Here are some tips to help you avoid stripping screws in the first place:
- Use the Right Size and Type of Screwdriver: Ensure that the screwdriver tip fits snugly into the screw head. Avoid using a screwdriver that is too small or too large.
- Apply Proper Pressure: Apply firm, steady pressure while turning the screwdriver. Avoid pressing too hard, which can cause the screwdriver to slip.
- Use High-Quality Screws: Invest in high-quality screws made from durable materials. Cheap screws are more likely to strip.
- Avoid Over-Tightening: Be careful not to over-tighten screws, especially when using power tools. Use a torque-limiting screwdriver or drill setting.
- Pre-Drill Pilot Holes: When working with hard materials, pre-drilling pilot holes can prevent screws from stripping.
Choosing the Right Screw Extractor Kit
If you frequently encounter stripped screws, investing in a good screw extractor kit is a wise decision. Look for a kit that includes a variety of sizes and types of extractors. Some kits also come with drill bits and other useful tools. Read reviews and choose a kit from a reputable brand to ensure quality and durability. Knowing how to get a stripped screw out is essential, but having the right tools makes the job much easier.
Troubleshooting Common Issues
Even with the best techniques and tools, you may still encounter some challenges when trying to remove a stripped screw. Here are some common issues and how to address them:
- The Screw Extractor Breaks: If the screw extractor breaks inside the screw head, it can be very difficult to remove. Try using a smaller extractor to remove the broken piece, or resort to drilling out the screw head.
- The Screw is Stuck Tightly: If the screw is heavily corroded or stuck, apply penetrating oil and let it soak for an extended period. You may also need to use heat to help loosen the screw.
- The Surrounding Material is Damaged: Be careful not to damage the surrounding material when trying to remove a stripped screw. Use masking tape to protect the surface, and work slowly and carefully.
Conclusion
Dealing with a stripped screw can be frustrating, but with the right techniques and tools, it’s often possible to remove it without causing further damage. Remember to start with the simplest methods and progress to more complex ones as needed. And most importantly, take your time and work carefully. By following the tips and techniques outlined in this guide, you’ll be well-equipped to tackle even the most stubborn stripped screws. Knowing how to get a stripped screw out is a valuable skill for any DIYer or professional, saving you time, money, and frustration.
