Why Screws Strip in the First Place
Every stripped screw has the same backstory: the driver bit didn’t grip the recess properly, and the drill kept turning anyway. The Phillips head was designed to cam out — that’s not a flaw, it’s how the original design worked, pushing the bit out before you over-torqued an assembly line joint. A century later, that cam-out habit is what rounds off screw heads in home workshops everywhere. The other usual suspects are mismatched bits (a PZ2 in a PH2 screw is a classic), bits worn smooth from months of abuse, driving at full speed with no pilot hole, and — the most common one — the wrong clutch setting on your drill.
Here’s the good news: a stripped screw is almost never a lost cause. There are about seven reliable methods, ordered from easiest to most destructive, and the first three solve roughly nine out of ten cases. The trick is knowing which one to try first instead of jumping straight to the Dremel.
Before you start, take a breath and assess the screw. Is the head fully rounded or just partially chewed? Can you reach it straight-on? Is it a flat-head screw sitting flush, or a pan-head sticking out? Your answers decide which method you reach for. And a note that applies to all of them: go slow, press firmly, and let the tool do the work. The impatient version of every method below is what stripped the screw in the first place.
Method 1: Switch to the Correct, Fresh Bit (and Adjust Your Technique)
Before anything clever, check whether the screw is truly dead. More stripped screws than you’d think can still be backed out with the right bit and the right approach.
First, identify the recess honestly. Phillips and Pozidriv look nearly identical but aren’t interchangeable — a Pozidriv bit in a Phillips screw (or vice versa) rides up and out. Torx and Robertson heads are far harder to strip because the bit seats deep; if you’re looking at one of those, a fresh bit of the exact size usually solves it.
Second, use a brand-new bit. A bit that’s driven a thousand screws has rounded edges you can’t see without magnification, and it will cam out of a compromised head instantly. Pop in a fresh one of the correct type and size — it costs almost nothing and fixes a surprising share of “stripped” screws.
Third, change your technique. Set your drill to the lowest speed, engage the clutch at a medium setting (our torque settings guide explains why this matters), press the bit firmly into the head, and turn slowly. Maximum downward pressure, minimum speed. The firm pressure keeps the bit seated; the slow speed keeps it from camming out again. If the screw moves even a quarter turn, you’re winning — back it out patiently from there.
Method 2: The Rubber Band Trick (Actually Worth Trying)
You’ve probably seen this one in videos and dismissed it. Don’t. A thick rubber band between the bit and the screw head adds friction and fills the chewed-out gaps in the recess, and on a partially stripped screw it genuinely works.
Lay a wide rubber band — the kind that comes on produce or in the mail — flat over the screw head. Press the correct driver bit firmly through the band and into the recess, and turn slowly with heavy downward pressure. The rubber conforms to the damaged grooves and gives the bit something to grip.
The honest caveats: this works best on screws that are partially stripped, not fully rounded. And if the rubber band is thin or the bit is a poor fit, it does nothing. But it’s a thirty-second test that costs nothing, so there’s no reason not to try it before reaching for real tools.
Method 3: Steel Wool or Abrasive Powder for Extra Grip
Same principle as the rubber band, more aggressive. A small wad of fine steel wool packed into the recess, or a pinch of abrasive powder — valve grinding compound from an auto parts store is the classic, and some people use coarse sand or even baking soda — increases the friction between bit and screw.
Press your bit through the material into the recess and turn slowly with firm pressure. The grit bites into both the bit and the screw, giving you grip where the rounded metal offers none. This is the method mechanics reach for when the rubber band fails, and it’s the last of the non-destructive options. If this doesn’t move it, the head is too far gone for friction tricks, and it’s time to cut into metal.
Method 4: The Screw Extractor Set (The Proper Tool for the Job)
A screw extractor set — the kind with reverse-threaded tapered bits, usually under twenty dollars — is the correct dedicated tool, and if you strip screws more than once a year, owning one pays for itself the first time you use it. There are two common styles, and they work a little differently.
The drill-and-extract type comes with two ends. First you drill a pilot hole into the center of the stripped head using the drilling end (or a small regular bit, typically 1/16 to 1/8 inch). Then you flip to the extractor end, which is tapered with a reverse (left-hand) thread, seat it in the hole, and run the drill in reverse. The reverse threads bite into the metal as you turn counter-clockwise, and the screw backs out with the extractor.
The one-piece extractor bit is simpler: it looks like a stepped drill bit and you just run it in reverse directly into the damaged head. No separate pilot hole needed.
Two things that make extractors fail: drilling the pilot hole off-center (the extractor walks and chews the head worse), and using a hammer blow to seat the extractor, which can snap small screws. Center-punch the head first so your bit doesn’t wander, keep everything slow, and let the reverse thread do the grabbing. A drop of penetrating oil around the screw threads ten minutes before you start — especially on rusty outdoor screws — makes every method in this list easier.
Method 5: Cut a New Slot With a Rotary Tool
When the recess is beyond saving, give the screw a new one. A rotary tool with a thin cutoff wheel lets you cut a straight slot across the stripped head, turning it into a flat-head screw you can remove with a regular flat-blade driver.
The slot needs to be deep enough for the flat bit to seat — roughly a millimeter or two — and centered enough that you can apply even pressure. A steady hand matters more than speed here; score the slot in a few light passes rather than one deep plunge, which overheats the metal and can snap the wheel. Wear eye protection — cutoff wheels throw sparks and occasionally shatter.
This works best on screws with heads that sit proud of the surface, where you can get the wheel in horizontally. On a screw buried in a countersunk hole, you usually can’t reach the head with the wheel, and you need Method 6 or 7 instead.
Method 6: Grab the Head With Locking Pliers
If any part of the screw head sticks out — even a couple of millimeters — forget the recess entirely and grab the outside. Locking pliers (Vise-Grips) clamped firmly onto the head will turn most screws out, no matter how chewed the inside is.
The technique: clamp the pliers as tight as you can get them, perpendicular to the screw, and turn the whole tool counter-clockwise. On stubborn screws, rocking the pliers slightly while turning helps break the initial seizure. For small screw heads that round pliers can’t grip, needle-nose locking pliers or a dedicated screw-removal plier with serrated jaws gets into tighter spots.
This is also the answer for screws whose heads have snapped off entirely — if there’s enough shank exposed, grab the shank the same way. When the head is below the surface and there’s nothing to grab, the pliers have nothing to work with, which brings us to the last resort.
Method 7: Drill the Head Off (The Nuclear Option)
Sometimes the screw wins and the head has to go. If the screw is holding two pieces together and you can live with extracting the shank later, drill the head off entirely. Pick a drill bit slightly larger than the screw’s shank but smaller than the head, center it carefully, and drill straight down at moderate speed with light pressure until the head separates from the shaft. The parts come apart, and the headless shank can usually be grabbed with pliers and twisted out.
Two warnings. First, keep the bit centered — wandering off-center gouges the workpiece, which is usually the thing you’re trying to save. A center punch mark is your best friend here. Second, wear eye protection and control the speed; you’re drilling hardened metal and broken bits are a real possibility. Our guide to drilling straight holes covers the slow, centered technique that makes this work cleanly.
Preventing Stripped Screws: What Changes After This
Removing one stripped screw is a skill; never stripping another is a habit. The prevention list is short and it all comes down to what you do before the bit starts turning:
- Match the bit to the screw, exactly. PH vs PZ matters. Torx vs hex matters. When in doubt, the bit should seat into the recess with no wiggle at all.
- Replace worn bits. Bits are consumables. The moment a Phillips tip looks rounded instead of crisp, it’s retired — keeping it is how you got here.
- Drill a pilot hole. Hardwoods and metals demand one; softwoods near edges and ends benefit hugely. The right pilot size is roughly the diameter of the screw’s shank (not the threads) — our drill bits guide covers sizing.
- Use the clutch. A drill-driver’s clutch exists to stop exactly this. Set it low for small screws and soft material, and let it ratchet instead of camming out.
- Slow down. High speed is for drilling; driving screws wants low gear and firm, steady pressure. The last quarter-turn by hand with a screwdriver gives you control the drill can’t.
And if you’re building or repairing anything regularly, consider switching your go-to fasteners to Torx or Robertson screws. Their recesses seat deeper and resist cam-out far better than Phillips. Once you drive a Torx screw, the Phillips starts to feel like what it is — a design from 1936 that we’ve all agreed to keep tolerating.
The Bottom Line
Work the ladder in order: fresh correct bit with firm pressure, rubber band, steel wool or abrasive, screw extractor, cut a new slot, locking pliers, and only then drill the head off. Most stripped screws surrender at step one or two. The ones that don’t will respect the extractor or the cutoff wheel. And the next time a screw starts to cam out, stop immediately — the cheapest stripped screw to remove is the one you never fully strip.
