A stripped screw can stop a repair in seconds, especially when your screwdriver keeps slipping instead of gripping. Knowing how to remove a stripped screw gives you a way to regain control without making the damage worse. With the right approach, even stubborn screws can be loosened and removed cleanly.
1. Find the Type of Stripped Screw Before You Start
Removal becomes easier once you know what type of screw you are dealing with and how badly the head is damaged. Different fasteners respond better to different tools, so identifying the shape and condition first can prevent further stripping.
- Phillips Screws: Cross-shaped heads can wear down when the wrong screwdriver size is used or too much pressure is applied. Depending on the damage, a larger bit, rubber band, locking pliers, or extractor may provide better grip.
- Allen (Hex) Screws: Six-sided sockets often become rounded after repeated slipping. Slightly larger hex bits, Torx bits, locking pliers, or extractors can sometimes create enough contact to loosen the screw.
- Torx Screws: Star-shaped heads usually offer a strong grip, but damaged points can still make removal difficult. Start with the correct Torx size, then move to a larger bit or extractor only if the recess is too worn.
- Rusted vs. Stripped Screws: Stripped screws have damaged drive recesses, while rusted screws may remain intact but become seized by corrosion. Rust usually calls for penetrating oil and patience, whereas stripping requires a method that restores grip or extracts the fastener.
2. How to Remove a Stripped Screw for Each Screw Type
Different screw heads fail in different ways, so the best removal method depends on the shape of the recess and how much grip is left. Start with the least aggressive technique first, then move to stronger extraction methods only when simpler options no longer work.
How to Remove a Stripped Allen screw
Rounded Allen sockets often lose contact between the key and the inner walls, making normal turning difficult. A better grip can sometimes be restored by changing the bit shape or using an extractor before drilling becomes necessary.
- Clean debris from the socket so the tool can sit as deeply as possible.
- Try a fresh Allen key in the correct size before moving to other methods.
- Tap a slightly larger Torx bit gently into the rounded socket if enough material remains.
- Turn slowly with firm downward pressure to reduce slipping.
- Use a screw extractor if the head is too damaged for normal bits.
- Replace the screw once removed rather than reusing the damaged fastener.
How to Remove a Stripped Phillips screw
Phillips heads usually strip when the driver cam-outs and wears away the cross-shaped recess. Extra friction or a better-fitting bit may be enough when the damage is mild, while badly rounded heads may need pliers or an extractor.
- Clear dirt or metal shavings from the recess.
- Try a larger Phillips bit that fits more tightly into the remaining grooves.
- Place a rubber band between the bit and screw head to increase friction.
- Apply steady downward pressure while turning counterclockwise.
- Grip the outer edge with locking pliers if the head protrudes above the surface.
- Move to a screw extractor when the recess can no longer hold a driver.
How to Remove a Stripped Hex screw
Stripped hex screws are similar to rounded Allen screws because both rely on a six-sided internal socket. The goal is to create fresh contact inside the recess without damaging the surrounding material.
- Remove loose debris and inspect how much of the hex shape remains.
- Test a slightly larger hex bit for a tighter fit.
- Tap in a Torx bit carefully if the rounded socket cannot hold the original tool.
- Turn slowly while maintaining strong, even pressure.
- Use penetrating oil first if corrosion is making the screw harder to move.
- Finish with an extractor when standard bits cannot generate enough grip.
3. How to Remove a Screw with a Stripped Head
Once the drive recess is too damaged for a screwdriver to grip normally, removal becomes a matter of creating new traction or grabbing the screw from the outside. Begin with the gentlest option available, then move toward extraction or drilling only if the head remains stuck.
- Clean the screw head to remove dust, rust flakes, paint, or metal debris.
- Try a fresh screwdriver bit that fits the remaining recess as tightly as possible.
- Place a rubber band or abrasive material between the bit and screw to improve friction.
- Apply firm downward pressure while turning slowly counterclockwise.
- Use locking pliers if enough of the screw head sits above the surface to grip securely.
- Cut a straight slot across the head with a rotary tool, then use a flathead screwdriver if the surrounding material allows.
- Use a screw extractor for heads that are too rounded or damaged for normal tools.
- Drill the head off only as a last resort, then remove the remaining shaft with pliers after separating the attached material.

4. Common Mistakes That Make a Stripped Screw Worse
Small errors during removal can turn a manageable screw into one that is much harder to extract. When learning how to remove a stripped screw, protecting the remaining edges of the head should be the priority before using more aggressive tools.
Using the Wrong Bit Size
A bit that is too small, too large, or poorly matched to the screw head can slip repeatedly and wear away the remaining grooves. Always test the closest-fitting size first and make sure the bit sits deeply and securely before applying torque.
Applying Too Much Speed
Fast drilling or rapid screwdriver movement can generate heat, increase slipping, and damage the recess even further. Use slow, controlled turns with steady pressure so the tool has a better chance of maintaining contact with the screw.
Forcing the Screw Without Loosening Rust
Corrosion can lock the threads in place even when the head still has some usable grip. Trying to overpower a rusted screw may strip it completely. Apply penetrating oil, allow time for it to work, then try removal again with controlled pressure.
