How to Remove a Stripped Screw: A Comprehensive Guide
Stripped screws can be a frustrating problem for anyone who works with tools, whether you’re a professional tradesperson or a DIY enthusiast. A stripped screw occurs when the head of the screw becomes damaged, making it difficult or impossible to remove with a standard screwdriver. This article will provide a detailed guide on how to remove a stripped screw, including various methods, tools needed, and tips for prevention. Additionally, we will include a FAQ section and a table summarizing the methods discussed.
Understanding Stripped Screws
A stripped screw is characterized by a damaged head that no longer allows the screwdriver to grip properly. This can happen for several reasons:
- Over-tightening: Using excessive force when tightening screws can strip the head.
- Incorrect Tool: Using the wrong size or type of screwdriver can lead to stripping.
- Wear and Tear: Over time, screws can wear down, especially if they are made of softer materials.
Tools and Materials Needed
Before attempting to remove a stripped screw, gather the following tools and materials:
- Screwdriver (flathead or Phillips, depending on the screw type)
- Rubber band or elastic band
- Pliers (needle-nose or locking pliers)
- Screw extractor kit
- Hammer
- Drill with drill bits
- Dremel tool (optional)
- Wood filler or super glue (for rethreading)
Methods for Removing a Stripped Screw
Method 1: Using a Rubber Band
- Place the Rubber Band: Take a wide rubber band and place it over the stripped screw head.
- Insert the Screwdriver: Press the screwdriver into the rubber band and turn slowly. The rubber band provides extra grip, which may allow you to turn the screw.
- Apply Pressure: If the screw begins to turn, continue applying pressure until it is fully removed.
Method 2: Using Pliers
- Grip the Screw: If the screw head is protruding enough, use needle-nose pliers to grip the sides of the screw head.
- Turn the Screw: Turn the pliers counterclockwise to remove the screw.
- Use Locking Pliers: If the screw is flush with the surface, use locking pliers to grip the screw tightly and turn it.
Method 3: Screw Extractor Kit
- Select the Right Extractor: Choose a screw extractor that fits the size of the stripped screw.
- Drill a Hole: Use a drill to create a small hole in the center of the stripped screw head.
- Insert the Extractor: Tap the extractor into the hole using a hammer.
- Turn the Extractor: Turn the extractor counterclockwise using a wrench. The extractor’s threads will grip the screw and allow you to remove it.
Method 4: Dremel Tool
- Create a Slot: If the screw head is too damaged, use a Dremel tool with a cutting wheel to create a new slot in the screw head.
- Use a Flathead Screwdriver: Insert a flathead screwdriver into the new slot and turn counterclockwise to remove the screw.
Method 5: Drilling Out the Screw
- Select a Drill Bit: Choose a drill bit slightly larger than the screw head.
- Drill into the Screw: Carefully drill into the center of the screw head until it is removed. Be cautious not to damage the surrounding material.
- Remove the Remnants: Once the head is removed, use pliers to extract the remaining screw shaft.
Preventing Stripped Screws
To avoid stripping screws in the future, consider the following tips:
- Use the Correct Tool: Always use the right size and type of screwdriver for the screw.
- Apply Even Pressure: When tightening screws, apply even pressure to avoid over-tightening.
- Pre-drill Holes: For wood screws, pre-drill holes to prevent splitting and stripping.
- Use Quality Screws: Invest in high-quality screws that are less likely to strip.

FAQ Section
Q1: What causes a screw to become stripped?
A: A screw can become stripped due to over-tightening, using the wrong size screwdriver, or wear and tear over time.
Q2: Can I prevent screws from stripping?
A: Yes, by using the correct tools, applying even pressure, and pre-drilling holes, you can reduce the likelihood of stripping screws.
Q3: What should I do if none of the methods work?
A: If all methods fail, consider seeking professional help or using a more aggressive method like drilling out the screw.
Q4: Are there special tools for removing stripped screws?
A: Yes, screw extractor kits are specifically designed for removing stripped screws and can be very effective.
Q5: Can I use super glue to fix a stripped screw?
A: Yes, you can apply super glue to the screw and let it set before attempting to turn it again, but this is a temporary solution.
Q6: Is it safe to drill out a stripped screw?
A: Yes, but be cautious to avoid damaging the surrounding material. Use the appropriate drill bit size.
Q7: What if the screw is in a delicate material?
A: In delicate materials, proceed with caution. You may want to use a rubber band or pliers first to avoid damage.
Q8: How do I know if a screw is stripped?
A: A stripped screw will not turn when you apply pressure with a screwdriver, or it may turn loosely without coming out.
Q9: Can I rethread a stripped screw hole?
A: Yes, you can use a tap and die set to rethread the hole, or use a larger screw if the material allows.
Q10: Where can I find more information about screws and tools?
A: For more information, you can visit Wikipedia on Screws.
