Ever turned a screwdriver, felt it spin freely, and realized with a sinking feeling that the screw head is now a smooth, useless crater? Almost everyone who has assembled furniture, opened a laptop, or fixed a wobbly cabinet door has hit this wall. A stripped screw can turn a five-minute job into an afternoon of frustration. The good news is that the problem is almost always solvable, and you usually don’t need a pro. With the right approach, most stripped screws come out in minutes.
This guide walks through why screws strip, which removal methods actually work, and how to avoid making the damage worse. It covers everything from the rubber band trick to drilling out a fastener as a last resort, plus how to repair the hole afterward so the fix lasts.
Why Screws Strip in the First Place
A stripped screw is one whose drive recess, the shaped slot the driver fits into, has rounded or deformed enough that the driver can no longer transmit torque. The metal doesn’t fail all at once. Instead, the edges of the recess slowly wear down until the driver just spins.
Several things cause this. The most common is using the wrong driver size or type. A Phillips driver that’s slightly too small will cam out, meaning it slips out of the recess under load, and each slip shaves a little metal off the head. The cross-shaped Phillips drive was actually designed to cam out at a set torque, which protects the fastener but makes it prone to stripping over repeated use. You can read more about how the cross recess works and why it slips in this overview of the Phillips screw. Japanese JIS cross screws look nearly identical to Phillips but have a slightly different recess, and a Phillips driver will chew them up quickly.

Other culprits include soft or cheap metal, corrosion that welds the screw to its hole, over-tightening, and power tools run at high speed without enough downward pressure. Knowing the cause helps you pick the right fix.
Start With the Least Invasive Fixes
Before reaching for drills, try the gentle options. They cost nothing and often work, especially on mildly damaged heads.
Use the Correct Driver and Press Hard
Many “stripped” screws aren’t stripped at all. They’re just being turned with the wrong bit. Switch to a driver that fits the recess exactly, press down firmly to seat it, and turn slowly. Downward pressure is the secret. It keeps the bit engaged and stops it from climbing out of the slot.
The Rubber Band Trick
Place a wide rubber band flat over the screw head, push the driver into it, and turn while pressing hard. The rubber fills the gaps in the worn recess and adds grip. This is a widely repeated folk method rather than a documented technique, so treat it as a cheap first attempt, not a guaranteed fix. It works best on screws that are only slightly rounded.
Abrasive Grit for Extra Bite
A pinch of valve-grinding compound, a dab of toothpaste with grit, or a small piece of steel wool placed in the recess can do what the rubber band does: increase friction between the driver and the damaged head. It’s messy but effective on stubborn heads.
Penetrating Oil and Heat for Seized Screws
If the screw is stuck because of corrosion rather than a damaged head, the problem is seizure, not stripping. Apply penetrating oil and let it sit for a while before trying again. Gentle heat from a heat gun or soldering iron can help break the corrosion bond through expansion and contraction. This is standard workshop practice rather than a standardized procedure, so use judgment and keep heat away from plastics and flammable materials.
When the Head Is Too Far Gone: Mechanical Removal
Once the recess is genuinely rounded, friction tricks stop working and you need to cut new grip or bite into the metal.
Cut a New Slot
If you have a rotary tool with a cutting wheel or a fine hacksaw blade, cut a straight slot across the damaged head. Then use a flathead screwdriver to back the screw out. This turns a ruined cross recess into a fresh slot in seconds. The catch is that you need access to the head and enough clearance to work. Protect nearby surfaces with tape, and wear eye protection, because cutting throws sparks and metal fragments.
Use a Screw Extractor
A screw extractor is the standard tool for this job. The common type is a tapered bit with left-hand threads. You drill a small pilot hole into the center of the damaged head, insert the extractor, and turn it counterclockwise. The threads bite into the metal and grip harder as you turn. This overview of screw extractors explains the different types and the drill-and-bite method in more detail.
Here’s the practical sequence:
- Center-punch the middle of the screw head so the drill doesn’t wander.
- Drill a pilot hole sized to match the extractor you’re using.
- Insert the extractor and turn it counterclockwise with a tap wrench or pliers.
- Keep steady pressure and turn slowly. Rushing can snap the extractor, which is hardened steel and very hard to remove.
Try a Left-Hand Drill Bit
Left-hand drill bits spin in reverse. When you run one in a drill set to reverse, the bit often catches the damaged fastener and backs it out during drilling, no extractor needed. It’s a favorite trick among mechanics because it saves a step. If the bit doesn’t catch, you’ve still drilled the pilot hole you needed for an extractor.
Grab the Head With Pliers
If the screw head sticks up above the surface, locking pliers or vise grips can clamp onto it and turn it out. This works well on pan-head and hex-head screws. File two flat sides onto the head first if the pliers keep slipping.
Last Resort: Drilling Out the Screw
Sometimes nothing grips, and the screw has to go. Drilling out means destroying the fastener so you can remove it and repair the hole. (Remove iphone calendar virus fixing calendar spam fast)
- Center-punch the head and drill a pilot hole.
- Step up to a drill bit slightly smaller than the screw’s shaft diameter.
- Drill straight and slow, checking often. When you reach the depth of the head, the head often pops off or the remaining shaft can be pried out.
- Remove any leftover shaft with pliers or an extractor.
This is the point where patience matters most. A wandering drill bit can scar the surrounding surface, and drilling at an angle can damage the threads in the hole. If the screw is in a delicate surface like a laptop shell or a cabinet face, consider stopping and asking a repair shop before you drill.
Repairing the Hole After Removal
Pulling the screw is only half the job. The hole is often enlarged or its threads are damaged, so a new screw won’t hold. The fix is a threaded insert, a metal sleeve that restores machine threads inside the hole. Helical inserts are the common type; you drill and tap the hole to a larger size, then screw in the insert. This overview of threaded inserts covers the main styles and where each is used. For wood, the simpler fix is to glue in a wooden plug or matchstick, let it dry, and drive a slightly larger screw. For metal, thread inserts are the durable answer. (Screw)
If you’re replacing the fastener, match the thread standard. Metric and imperial threads follow different specifications, and mixing them up is a common mistake that leads to cross-threading. This explanation of screw threads covers the standards behind replacement sizing.
Mistakes That Make Things Worse
A few habits turn a small problem into a big one. Avoid them.
- Using a power drill on a damaged head. High speed and torque round the recess faster than hand tools.
- Pushing a too-small bit. It feels like it fits, but it slips and shaves metal.
- Skipping eye protection. Metal fragments from drilling and cutting are a real hazard.
- Forcing a stuck screw. If it won’t budge, stop and add oil or heat rather than muscling it.
- Drilling without a center punch. The bit wanders and damages the surface around the screw.
Tools Worth Keeping on Hand
A small stripped-screw kit saves hours. The essentials are a set of screw extractors, left-hand drill bits, a center punch, a rotary tool with cutting wheels, locking pliers, penetrating oil, and safety glasses. If you work on electronics, add precision drivers in the correct sizes, since the tiny screws in phones and laptops strip easily.

Preventing Stripped Screws Next Time
Prevention is mostly about technique. Use the right driver size and type every time, and press down firmly before turning. Start screws by hand and only finish with power tools at low torque. Keep a little lubricant or anti-seize on screws that live outdoors or in damp places. When a screw starts to feel loose in the recess, stop immediately and switch to a fresh bit or a different method. That one pause prevents most stripped heads.
Conclusion
A stripped screw feels like a dead end, but it rarely is. The fix usually follows a simple ladder: try the right driver and firm pressure first, add friction with a rubber band or abrasive grit, then move to cutting a new slot or using a screw extractor. Drilling out is the fallback, and thread inserts repair the hole afterward. The key is to stop early when a screw starts to slip, because every extra turn makes the damage worse. With a small kit and a bit of patience, most stripped screws come out cleanly, and the surface around them stays untouched.
Frequently Asked Questions
What does it mean when a screw is stripped?
A stripped screw has a damaged drive recess, the shaped slot the screwdriver fits into. The edges round off, so the driver spins without turning the screw. It can also mean the threads in the hole are damaged, which is a different problem with a different fix.
Can I remove a stripped screw without a drill?
Yes, in many cases. The rubber band trick, abrasive grit, a correctly sized driver with firm pressure, locking pliers on a protruding head, or cutting a new slot with a rotary tool can all work without a drill. A drill is only needed for extractors or for drilling out the screw entirely.
Does the rubber band trick actually work?
It can work on mildly rounded screws because the rubber fills gaps and adds grip. It’s a widely shared folk method rather than a documented technique, so treat it as a free first attempt. It won’t rescue a screw whose recess is completely smooth.
What is a screw extractor and how does it work?
A screw extractor is a tapered bit with left-hand threads. You drill a pilot hole into the damaged head, then turn the extractor counterclockwise so its threads bite into the metal and grip harder as you turn. It’s the standard tool for badly stripped screws.
How do I fix the hole after removing a stripped screw?
For metal, install a threaded insert to restore machine threads. For wood, glue in a wooden plug or matchstick, let it dry, and drive a slightly larger screw. Matching the correct thread standard when choosing a replacement prevents cross-threading.
How can I avoid stripping screws in the first place?
Use the exact driver size and type, press down firmly before turning, start screws by hand, and finish with power tools only at low torque. Stop as soon as a screw feels loose in the recess, since every extra turn makes the damage worse.
