Fixing a stripped screw can be frustrating, especially when you need to finish a project quickly. It often happens when the screw head is worn down, making it difficult or impossible for a screwdriver or drill bit to grip the screw.
Many people face this problem when doing home repairs, furniture assembly, or even simple DIY tasks. But with the right techniques, you can remove or fix a stripped screw without damaging your materials. In this guide, you’ll learn multiple ways to handle stripped screws, what tools to use, how to prevent the problem, and some clever tricks that even many experienced DIYers may not know.
What Is A Stripped Screw?
A stripped screw means the slots or grooves in the screw head are damaged. Instead of being sharp and defined, the edges are rounded or worn down. This usually happens because of using the wrong tool, too much force, or poor-quality screws. The screwdriver or drill bit cannot get a good grip, so the screw won’t turn and gets stuck.
Stripped screws are common with Phillips and slotted screws, but they can occur with any type, including Torx and hex screws. Once a screw is stripped, it can slow down your work and sometimes even ruin the material if you’re not careful.
Why Do Screws Get Stripped?
Understanding why screws get stripped helps you avoid the problem in the future. Some main causes include:
- Wrong tool size: Using a screwdriver or bit that does not fit the screw head snugly.
- Poor quality screws: Cheap screws are made from soft metals that wear out quickly.
- Over-tightening: Applying too much force, especially with a power tool, can destroy the head.
- Wrong tool angle: Not keeping the tool straight can cause uneven pressure and rounding.
- Old or reused screws: Screws that have already been used may not hold up well.

How To Remove A Stripped Screw: Step-by-step Methods
There are many ways to remove a stripped screw, depending on the tools you have and how badly the screw is damaged. Here are the most effective methods, from simple tricks to more advanced techniques.
1. Use A Rubber Band For Extra Grip
One of the quickest solutions is to place a rubber band over the stripped screw head. The rubber creates friction and fills the gaps, helping the tool grip the screw better.
How to do it:
- Place a wide rubber band flat over the screw head.
- Firmly press the screwdriver or bit into the rubber band and turn slowly.
- If the screw starts to move, keep steady pressure and turn until it comes out.
Tip: Use a thick, sturdy rubber band. Thin bands may tear under pressure.
2. Try A Different Screwdriver Or Bit
Sometimes, simply switching tools does the trick. If you used a Phillips screwdriver, try a flathead, or vice versa. For star-shaped screws, try a slightly larger or smaller Torx bit.
- Press down hard and turn slowly. Avoid using power tools, as they can make the damage worse.
- If you have a manual impact driver, it can help by delivering a turning force and a shock at the same time.
3. Use Pliers Or Locking Pliers
If the screw head is sticking out above the surface, locking pliers (like Vise-Grips) or regular pliers can grab the head and turn it out.
- Open the pliers, clamp them tightly around the screw head, and twist slowly.
- Work gently to avoid breaking the screw or damaging the surrounding material.
This method is especially useful for larger screws or when you don’t care about saving the screw.
4. Cut A New Slot With A Rotary Tool Or Hacksaw
If the screw head is badly stripped, you can cut a new groove across the head using a rotary tool (like a Dremel) or a small hacksaw blade. This creates a slot for a flathead screwdriver.
- Wear safety goggles to protect your eyes from metal shavings.
- Cut a straight, deep slot across the screw head.
- Insert a flathead screwdriver into the slot and turn slowly.
5. Use A Screw Extractor Set
A screw extractor is a special tool designed for removing damaged screws. These are available at most hardware stores and come in different sizes.
- Choose the right size extractor for your screw.
- Drill a small hole into the center of the screw head (if needed).
- Insert the extractor and turn it counterclockwise. The reverse threads grip the screw and pull it out.
Pro tip: Go slow and keep the extractor straight to avoid breaking it inside the screw.
6. Tap The Screwdriver With A Hammer
A gentle tap can help seat the screwdriver or bit into the screw and break loose any corrosion or paint.
- Place the screwdriver into the screw head.
- Lightly tap the handle with a hammer while turning.
- This works best for screws stuck due to rust or paint.
7. Apply Heat To Loosen The Screw
Heat can cause the screw and the surrounding material to expand, making it easier to remove.
- Use a soldering iron or heat gun to warm the screw for a few minutes.
- Be careful with plastic or painted materials, as they can melt or discolor.
- Try turning the screw while it’s still warm.
8. Use Chemical Penetrants
If the screw is rusted or stuck due to corrosion, a penetrating oil like WD-40 can help.
- Spray the oil onto the screw and let it soak for 10-15 minutes.
- Try removing the screw with a screwdriver or pliers.
9. Drill Out The Screw
As a last resort, you can drill the screw out.
- Use a drill bit slightly smaller than the screw shaft.
- Drill straight into the center of the screw head until the head comes off.
- Once the head is removed, you can pull the material apart and use pliers to remove the rest of the screw.
This method can damage the material, so use it carefully.
10. Use Left-handed Drill Bits
A left-handed drill bit turns in the opposite direction of a normal bit. Sometimes, just drilling into the screw with a left-handed bit will unscrew it.
- Choose a bit slightly smaller than the screw.
- Drill slowly in reverse. If you’re lucky, the screw will back out as you drill.
Comparison Of Common Stripped Screw Removal Tools
Sometimes, choosing the right tool can be confusing. Here’s a quick comparison to help you decide what might work best in your situation:
| Tool | Best For | Success Rate | Skill Level |
|---|---|---|---|
| Rubber Band | Lightly Stripped Screws | Medium | Beginner |
| Pliers | Exposed Screw Heads | High | Beginner |
| Screw Extractor | Severely Damaged Screws | High | Intermediate |
| Cutting New Slot | Completely Stripped Heads | Medium | Intermediate |
| Drilling Out | All Else Fails | Low to Medium | Advanced |
Preventing Screws From Getting Stripped
Fixing a stripped screw is useful, but it’s even better to avoid the problem in the first place. Here’s how you can prevent screw heads from getting damaged:
- Choose the right screwdriver or bit. Make sure it fits the screw head perfectly. A loose fit leads to stripping.
- Use good-quality screws. Cheap screws are often made from soft metals and strip easily.
- Don’t overtighten. Once a screw is snug, stop turning. Too much force will damage the head.
- Keep your tools straight. Hold the tool at a 90-degree angle to the screw.
- Use the correct speed. If using a power tool, go slow when starting and finishing.
- Replace worn tools. Old, worn screwdrivers and bits slip easily and cause damage.
Non-obvious tip: If you work with painted screws, remove paint from the screw head with a razor blade before unscrewing. Paint can fill the grooves and make stripping more likely.
What To Do After Removing A Stripped Screw
Once you’ve removed the stripped screw, you might want to reuse the same hole or repair the material. Here’s how to deal with the aftermath:
Filling And Reusing The Hole
If the screw hole is damaged or too wide:
- Fill the hole with wood glue and small toothpicks or wooden dowels. Let dry, then drill a new pilot hole.
- For metal or plastic, use a two-part epoxy to fill the hole, then drill once cured.
Choosing A Replacement Screw
When replacing a stripped screw, pick one that is:
- Slightly larger in diameter
- Made from harder metal (stainless steel or brass)
- The same length or longer for deep grip
Repairing The Material
If you damaged the material around the screw, use wood filler for wood, or a patch kit for drywall. Sand and repaint if necessary.
Advanced Screw Removal Techniques
Sometimes, basic methods don’t work, especially if the screw is rusted, broken, or recessed. Here are some advanced tricks:
Welding A Nut To The Screw
If you have access to welding tools, weld a nut onto the top of the stripped screw. Use a wrench to turn the nut and remove the screw.
- This method works well for metal surfaces, but is not suitable for wood or plastic.
Using A Hammer And Punch
Place a center punch or a small chisel at the edge of the screw head. Tap it with a hammer to turn the screw counterclockwise. This method works best for large screws.
Reverse-threaded Taps
For screws broken below the surface, use a reverse-threaded tap to grip and remove the remains.
Comparison: Manual Vs. Power Tool Screw Removal
Choosing between manual and power tools can affect both your results and the risk of further damage.
| Method | Control | Risk of Damage | Speed | Best For |
|---|---|---|---|---|
| Manual Screwdriver | High | Low | Slow | Delicate Materials |
| Power Drill | Medium | Medium | Fast | Stuck Screws |
| Impact Driver | Medium | High | Fast | Rusted Screws |
Common Mistakes To Avoid
Many beginners make errors that make a stripped screw even harder to fix. Here’s what not to do:
- Don’t keep turning a stripped screw with the same tool. This makes it worse.
- Don’t use excess force right away. Try gentle methods first.
- Don’t drill without checking what’s behind the screw. You could damage wires or pipes.
- Don’t ignore safety. Wear eye protection, especially when cutting or drilling.
Less obvious mistake: Not checking for left-handed screws, especially in older appliances or machinery. Turning the wrong way will tighten, not loosen the screw.
When To Seek Professional Help
Sometimes, the screw is so stuck or the material is so valuable that DIY methods are risky. If you’re working on expensive furniture, electronics, or anything with safety concerns, it’s wise to call a professional. They have specialized tools and experience to remove screws without causing further damage.

Essential Tools For Screw Removal
Building a small screw removal kit at home can save you time and stress. Here’s what you should have:
- Screwdriver set (Phillips, slotted, Torx, hex)
- Screw extractor set
- Pliers (including locking pliers)
- Rubber bands
- Drill and bits (including left-handed bits)
- Penetrating oil

How To Fix A Stripped Screw Hole
Sometimes, the screw comes out, but the hole itself is stripped and won’t hold a new screw. Here’s how to fix it:
For Wood
- Insert toothpicks or matchsticks coated with wood glue into the hole.
- Break them off flush with the surface.
- Let the glue dry, then drill a small pilot hole and insert the new screw.
For Metal
- Use a thread repair kit (helicoil) to create new threads inside the hole.
- For thin metal, a larger screw may work if the hole allows.
For Drywall
- Fill the hole with drywall compound or patching material.
- Once dry, drill a new pilot hole.
Expert tip: For very heavy loads, use a wall anchor or toggle bolt instead of reusing a damaged hole.
How To Avoid Stripping Screws In The Future
Prevention is always better than repair. Here are some practical tips:
- Pre-drill pilot holes for screws, especially in hardwood or dense materials. This reduces resistance and lowers the chance of stripping.
- Use the right torque setting on your drill or driver. Many tools have adjustable settings.
- Clean out screw heads before removing. Dirt, paint, or rust can prevent the tool from seating correctly.
- Keep tools in good condition. Replace worn screwdriver tips and bits regularly.
- Lubricate screws with a little soap or wax when driving into hard materials.
Non-obvious Insights For Beginners
- Switch to a manual screwdriver for final turns. Even if you use a power drill for most of the screw, switch to a hand tool for the last few turns. This gives better control and reduces stripping.
- Try tightening before loosening. Sometimes, turning the screw slightly tighter can break the bond and make removal easier.
Real-world Example
Imagine you’re assembling a new bookshelf. One screw won’t turn and the head is stripped. You try the rubber band trick, but it fails. Next, you grab your locking pliers and manage to twist the screw out. The hole is now loose, so you fill it with toothpicks and glue, let it dry, and then re-insert a new screw.
The shelf is now secure.
This shows how using multiple methods together solves the problem without ruining your project.
Environmental Considerations
When removing screws from wood, plastic, or metal, think about how you dispose of old screws and damaged parts. Many screws can be recycled as metal waste. Avoid using harsh chemicals unless necessary, and keep your workspace clean.
