Knowing how to remove a stripped screw can keep a minor repair from turning into a damaged surface, broken component, or delayed project. Start with the least aggressive method, such as switching screwdriver bits or adding friction, and move to pliers, an extractor, or drilling only when simpler techniques fail.
A stripped screw has a damaged drive recess that no longer gives the screwdriver or drill bit enough grip to turn the fastener. The more the tool slips inside the screw head, the more difficult removal becomes.
The key is to stop using excessive force, assess the screw’s condition, and choose a removal method that matches the severity of the damage.
What Is a Stripped Screw?
A stripped screw is a fastener with a worn, rounded, or damaged head that prevents the correct driver bit from gripping it securely.
Most stripped screws begin with minor damage. Continued drilling or turning causes the driver to slip repeatedly, wearing down the edges of the screw’s drive recess until it can no longer transfer enough torque to loosen the fastener.
Common signs of a stripped screw include:
- The screwdriver spins without turning the screw.
- The drill bit repeatedly slips out of the screw head.
- The Phillips, slotted, Torx, square, or hex recess appears rounded.
- The screw turns slightly but remains stuck.
- Metal shavings appear around the screw head.
Once you notice the driver slipping, stop immediately. Continuing to apply power can make stripped screw removal significantly more difficult.
What Causes a Screw to Become Stripped?
Screws commonly become stripped because of an incorrect bit, excessive speed, poor alignment, worn tools, over-tightening, or resistance from the surrounding material.
Understanding the cause can help you choose the best removal technique and prevent the same problem from happening again.
Using the Wrong Driver or Bit Size
A driver that is too small does not fully engage the screw head. Instead of distributing force across the entire recess, it presses against a few small points and begins wearing them down.
A bit that is too large may not seat deeply enough to grip the screw correctly.
Driving the Screw at an Angle
The screwdriver or drill should remain directly aligned with the screw. When the tool is held at an angle, pressure becomes uneven and increases the likelihood that the driver will slip out of the recess.
Using Too Much Speed
High drill speeds make it harder to maintain control and can quickly damage the screw head. Low speed and steady downward pressure generally provide better grip.
Applying Excessive Torque
Continuing to drive a screw after it is fully seated can damage both the screw head and the surrounding material. This is especially common when a drill’s clutch setting is too high.
Using Worn Driver Bits
A worn or rounded bit cannot properly engage the screw head. Replace damaged bits before starting an installation or repair.
Skipping the Pilot Hole
Driving a screw directly into dense wood, metal, or another resistant material may require more torque than the screw can tolerate. A properly sized pilot hole reduces resistance and makes the screw easier to install.
How to Remove a Stripped Screw
The best way to remove a stripped screw is to begin with added grip and gradually move toward more aggressive extraction techniques.
Try the following methods in order. Stop as soon as one method works rather than continuing to damage the screw or surrounding surface.
1. Switch to a Manual Screwdriver
A manual screwdriver gives you more control and may grip a mildly damaged screw better than a drill.
Choose the correct driver style and the largest size that fits securely into the remaining recess. Press firmly downward while slowly turning the screwdriver counterclockwise.
Using a manual tool reduces speed and allows you to feel whether the driver is catching or slipping. Sometimes this added control is enough to loosen a screw before the head becomes completely rounded.
Do not continue if the screwdriver spins freely. Move to a different method before causing additional damage.
2. Try a Different Driver Bit
A slightly larger bit or a different drive style may catch against portions of the damaged screw head that remain intact.
For example, a flathead screwdriver may fit across a damaged Phillips recess. A Torx or square-drive bit may also grip a rounded opening in some situations.
Tap the alternative bit gently into the screw head so it seats securely. Apply firm downward pressure and turn slowly.
This method works best when the screw is only partially stripped and still has enough structure for another driver to grip.
3. Use a Rubber Band for More Grip
Placing a wide rubber band between the driver and the screw head can increase friction and help the bit grip a slightly stripped recess.
Lay the rubber band flat over the screw head. Press the screwdriver or drill bit firmly into the rubber and turn counterclockwise at a low speed.
The rubber fills small gaps between the bit and the damaged drive recess. This technique is most effective for screws with minor wear and is unlikely to work when the head is completely rounded. The friction method is also commonly recommended as an early removal attempt because it is less likely to damage the surrounding material.
4. Add Friction With Steel Wool or Abrasive Material
A small piece of steel wool can create additional contact between the tool and the damaged screw head.
Place the steel wool over the screw and press the driver through it. Keep the driver straight, apply firm downward pressure, and turn slowly.
A small amount of abrasive cleaning powder can serve a similar purpose by increasing friction. However, avoid loose abrasive materials around sensitive equipment, electronics, bearings, or finished surfaces.
5. Tap the Screwdriver Into the Head
Lightly tapping a manual screwdriver into the screw head can help the tool seat deeper into damaged metal.
Position the correctly sized screwdriver in the recess and tap the handle gently with a hammer a few times. Keep the screwdriver in place and slowly turn it counterclockwise.
Do not strike hard enough to drive the screw farther into the material. This method requires particular care when working with drywall, plastic, electronics, finished wood, or fragile components.
6. Grip the Screw With Locking Pliers
Locking pliers are one of the most effective stripped screw removal methods when part of the screw head remains above the surface.
Clamp the pliers firmly around the outside edge of the screw head. Turn the screw counterclockwise in small, controlled movements until it begins to loosen.
Once the screw rises farther from the surface, reposition the pliers for a stronger grip and continue turning.
This method will not work when the screw head is recessed or completely flush with the surrounding material.
7. Apply Penetrating Oil to a Stuck Screw
Penetrating oil can help loosen a stripped screw that is also rusted, corroded, or seized inside metal.
Apply a small amount around the screw threads or the point where the screw enters the material. Allow the oil time to penetrate before attempting removal again.
Protect nearby finishes and clean away excess oil before using an extractor or power tool. Penetrating oil is generally more helpful for metal-to-metal connections than screws installed in wood or plastic.
8. Cut a New Slot Into the Screw Head
Cutting a straight slot into an exposed screw head creates a new drive surface for a flathead screwdriver.
Use a rotary tool with a thin metal-cutting wheel to carefully cut a shallow groove across the center of the screw head. Insert a flathead screwdriver that fits the new slot tightly and turn counterclockwise.
Wear safety glasses because rotary cutting can create metal debris or sparks. Keep the tool away from wiring, fuel, flammable material, finished surfaces, and delicate components. Cutting a new slot is an established technique for severely damaged screw heads, but it should only be attempted when the surrounding area can be protected.
9. Use a Screw Extractor
A screw extractor is usually the best option when basic grip methods fail and the screw head is too damaged for a standard driver.
Most extractor kits use a hardened, reverse-threaded tool that bites into a pilot hole drilled into the damaged screw.
A typical stripped screw removal process includes:
- Select an extractor that matches the screw size.
- Mark the center of the screw head.
- Drill a small, centered hole using the recommended bit.
- Insert the extractor into the hole.
- Set the drill to reverse.
- Turn slowly until the extractor grips the screw.
- Continue turning until the screw backs out.
Follow the extractor manufacturer’s instructions because drill direction, hole depth, and bit selection can vary by product.
Low speed is critical. Excessive speed can prevent the extractor from gripping or cause the hardened tool to break inside the screw.
10. Use a Left-Hand Drill Bit
A left-hand drill bit rotates counterclockwise and may loosen the screw while drilling the pilot hole.
Center the bit carefully over the screw and operate the drill in reverse at a low speed. As the bit cuts into the fastener, the counterclockwise force may cause the screw to release without requiring a separate extractor.
Even when the screw does not come out, the hole may prepare it for a compatible screw extractor.
11. Drill Off the Screw Head
Drilling off the screw head is a last-resort method for screws that cannot be removed using a driver, pliers, or extractor.
Choose a drill bit approximately the width of the screw shaft and drill slowly through the center of the head. Once the head separates, remove the attached component and use locking pliers to turn the remaining screw shaft out of the material.
This method destroys the screw and may damage the part if the drill is not properly centered. Use it only when the screw will be replaced and the surrounding component can tolerate the procedure.
How to Unscrew a Stripped Screw From Wood
To unscrew a stripped screw from wood, begin with a manual screwdriver or friction method before using pliers or an extractor.
Wood can compress, split, or become enlarged around the screw, so avoid aggressive hammering and oversized drill bits.
When the screw head is exposed, locking pliers are often effective. If the head is flush, use a properly centered extractor. After removal, inspect the screw hole before installing a replacement.
A damaged hole may need to be repaired with a wood plug, dowel, approved filler, or a larger fastener suited to the application.
How to Remove a Stripped Screw From Metal
A stripped screw in metal may require penetrating oil, an impact tool, a left-hand drill bit, or a screw extractor.
Metal fasteners can become seized because of rust, corrosion, thread-locking compounds, heat, or excessive installation torque. Allow penetrating oil to work before applying more force.
When drilling metal:
- Wear eye protection.
- Keep the drill centered.
- Use an appropriate metal-cutting bit.
- Operate at a controlled speed.
- Prevent the workpiece from moving.
- Use cutting fluid when appropriate.
If the fastener is part of critical machinery, electrical equipment, a pressurized system, or a safety-related assembly, consult a qualified technician before drilling.
How to Remove a Stripped Screw From Plastic
Use the least aggressive method possible when removing a stripped screw from plastic.
Begin with a manual screwdriver, a larger bit, or a rubber band. Avoid excessive heat, hammering, and high-speed drilling because plastic can crack, deform, or melt.
If an extractor is necessary, drill slowly and use the smallest practical bit. Do not force the replacement screw back into damaged plastic threads.
How to Deal With Stripped Screws in Recessed Holes
A recessed stripped screw usually requires an alternative driver bit, screw extractor, or left-hand drill bit because pliers cannot reach the screw head.
Make sure the work area is well lit and remove debris from the recess. Select a bit that seats as deeply as possible and apply direct downward pressure.
If the head is fully rounded, carefully mark the center before drilling. A centered hole helps the extractor engage properly and reduces the chance of damaging the surrounding opening.
How to Loosen a Stripped Screw Without Damaging the Surface
Use controlled pressure, protect the surrounding material, and begin with the least invasive removal method.
Place painter’s tape around the screw head to protect finished surfaces from scratches. When using pliers, rotary tools, or drills, cover exposed areas with a thin protective sheet whenever possible.
Additional precautions include:
- Keeping the driver aligned with the screw.
- Using low drill speed.
- Supporting movable components.
- Avoiding unnecessary hammering.
- Stopping when a method begins causing more damage.
- Wearing eye protection when drilling or cutting.
The goal is not simply to remove the fastener. It is to remove it without creating a larger repair.
What Should You Do After You Have Removed the Stripped Screw?
After you have removed the stripped screw, inspect the hole, surrounding material, mating threads, and replacement fastener before reassembly.
Do not reinstall the damaged screw. A stripped fastener is more likely to slip, loosen, or become stuck again.
Check for:
- Damaged internal threads
- Enlarged holes
- Cracks or splitting
- Corrosion
- Metal shavings
- Misalignment
- Incorrect screw length or diameter
- Evidence of over-tightening
Replace the screw with the correct drive type, diameter, thread, length, material, finish, and strength rating for the application.

Frequently Asked Questions About Stripped Screw Removal
What is the easiest way to remove a stripped screw?
The easiest method is to switch to a properly sized manual screwdriver and apply firm downward pressure while turning slowly. For mild damage, adding a rubber band between the screwdriver and screw head may provide enough grip.
Can you remove a stripped screw without an extractor?
Yes. A stripped screw may be removed with a manual screwdriver, larger bit, rubber band, steel wool, locking pliers, penetrating oil, or a newly cut slot. The right method depends on how damaged and accessible the screw head is.
How do you remove a completely rounded screw?
Use locking pliers if the head is exposed. For a recessed or flush screw, use a left-hand drill bit or screw extractor. Drilling off the head should be reserved for cases where other options fail.
Can you use a drill to remove a stripped screw?
Yes. A drill can operate a left-hand bit or screw extractor. Use low speed, keep the hole centered, and follow the extractor manufacturer’s instructions.
Does a rubber band really remove stripped screws?
A rubber band can help when the screw is only slightly stripped. It fills small gaps and increases friction between the driver and the screw head, but it usually will not remove a completely rounded or seized screw.
How do you loosen a stripped screw that is rusted?
Apply penetrating oil around the fastener and allow it to work before attempting removal. Then use a manual driver, pliers, left-hand drill bit, or extractor depending on the screw’s condition.
Should a stripped screw be reused?
No. Replace a removed stripped screw with a new fastener that matches the required size, thread, material, finish, strength, and drive style.
