You know the feeling. You’re halfway through a project, the sun’s setting, and BAM. That one stubborn screw, the one with the star head, decides it’s had enough. The screwdriver just spins, mocking you. You can’t get that stripped star screw out, and suddenly, the whole day feels ruined.
I’ve been there more times than I care to admit. Wasted hours and a few bucks on tools that promised miracles but delivered frustration. It’s not just about brute force; it’s about knowing what actually works and when to call it quits before you make it worse.
This isn’t going to be one of those fancy articles full of jargon. This is the straight dope on how to deal with those stripped-out P.O.S. screws.
Why Star Screws Are the Devil’s Own Fastener
Let’s be honest, the Phillips head screw, and its fancier cousin, the Torx (or star) screw, were supposed to be an improvement. Less cam-out, they said. Better grip, they said.
Well, maybe for the factory assembly line. For us humans wrestling with them years later, especially in wood that’s swollen or metal that’s corroded, they’re a recipe for stripped-out disaster. The problem is, those little pointy bits inside the star head are really easy to round off, especially if you’re using the wrong size bit, a worn-out bit, or just too much torque. I once spent an entire Saturday trying to remove a single stripped Torx screw from a deck railing.
It looked like it was just a little chewed up, but after about an hour of trying different screwdrivers, different angles, and a liberal amount of colorful language, the head was completely smooth. The metal of the screw head is often softer than you’d think, and the torque you need to break it free can easily exceed the strength of those delicate points.
The real kicker is when you’re working on older furniture or equipment. The screws are often made of a softer metal to begin with, and over time, they can bind up something fierce. Moisture, rust, even just the natural expansion and contraction of materials can seize them up tighter than a drum. You think you’re just turning a screw, but you’re actually fighting against years of environmental abuse. And the star head, while it offers more points of contact than a Phillips, also means more places for damage to occur, and those little grooves are prime real estate for dirt and gunk to wedge in, further complicating matters.
I’ve seen people try to hammer in a slightly larger bit, or use pliers to grip the head. Sometimes that works on a really shallow, minor strip.
But more often than not, you just mangle the screw head further, making it impossible for any tool to grab it later. It’s a snowball effect of bad decisions.
The common advice to just ‘use the right size bit’ sounds great on paper, but when you’re looking at a screw that’s already half-way destroyed, that advice is about as useful as a screen door on a submarine. It’s not that the advice is wrong; it’s just that it doesn’t apply to the situation you’re in anymore.
You’re past the ‘right size bit’ stage, my friend.
The good news? There are actual, workable solutions. You just need to know where to look and what to expect. It’s a bit of a dive into the world of specialized tools and techniques, but trust me, getting that stripped screw out feels like a major victory. So, let’s break down what’s going on and how to fix it. The sheer frustration of facing a stripped screw head can make you want to just give up and buy a whole new piece of furniture, but it doesn’t have to come to that. Understanding the physics of why these things strip is half the battle.
When the Driver Just Spins: Your First Lines of Defense
Okay, so you’ve realized your screwdriver is doing more damage than good. The absolute first thing to try, before you do anything drastic, is to apply firm downward pressure while you try to turn. And I mean firm. Lean into it.
You want to keep that bit seated as deeply as possible in whatever remains of the screw head’s channels. Sometimes, a little bit of extra force is all it takes to get a purchase. I’ve had screws that felt completely stripped but came out with a good solid push and a slow, steady turn. Don’t just yank on the screwdriver; try to feel for any resistance, any hint of movement.

If it still just spins, then it’s time for something else.
Next up, and this is a trick that sounds too simple but works surprisingly often: put a wide rubber band between the screwdriver bit and the screw head. The rubber band fills in the damaged parts of the recess and can provide just enough extra grip for the driver to catch. It’s a low-tech solution that can sometimes get you out of a jam when specialized tools seem like overkill. You can also try a bit of abrasive material, like a tiny bit of valve grinding compound or even a sprinkle of Comet cleanser (though I’d use that sparingly and clean up well afterward).
The grit helps the screwdriver bit bite into the metal. I tried the rubber band trick on a small appliance I was fixing last month, and it worked like a charm on a slightly Phillips-stripped screw.
I was genuinely surprised.
Another thing people swear by is using a manual impact driver. This is a tool you hit with a hammer, and the impact forces the bit into the screw head while simultaneously turning it. It sounds violent, and it can be if you’re not careful, but it’s incredibly effective for breaking loose stubborn or slightly stripped screws. You have to make sure you set it to ‘reverse’ and use a bit that fits the remaining shape of the screw head as best as possible.
Don’t go nuts with the hammer; a solid rap is usually enough. The shock can break the bond of rust or thread locker that’s holding the screw in place. This is where having a good set of bits, including Torx and Phillips in various sizes, really pays off.
If you’re dealing with a really stubborn screw that’s also a Torx head, sometimes a Torx bit that’s one size larger than the original can be hammered in gently to get a bite. This is a last resort before you get into extractors. You’re basically trying to cut new, albeit shallow, grooves into the damaged recess. I’ve only had to do this a couple of times, and it’s risky because you can further damage the screw head if you’re not careful. But when it works, it’s a beautiful thing. The key is gentle persuasion, not brute force. Think of it as coaxing the metal into a new shape.
The Real Deal: Screw Extractors That Actually Work
When the simple stuff fails, it’s time for the pros. And by pros, I mean screw extractors. Forget those cheap, flimsy ones you see in blister packs at the dollar store. You need quality. My go-to recommendation is a set of spiral flute extractors. These are like reverse-threaded drill bits. You drill a pilot hole into the center of the stripped screw head, and then you insert the extractor into the hole and turn it counter-clockwise. As you turn, the reverse threads bite into the metal of the screw, and theoretically, unscrew it.
The trick with these is drilling the pilot hole correctly. It needs to be centered and deep enough for the extractor to get a good bite. If your drill bit wanders or goes too shallow, the extractor won’t grip properly, and you’ll just end up with a mangled screw and a slightly mangled extractor.
I learned this the hard way on a project involving an old engine part. I rushed the pilot hole, and the extractor just spun uselessly. I ended up having to use a Dremel to cut a slot into the screw head and then use a flathead screwdriver, which took forever.
So, take your time with the drilling. A center punch is your best friend here to make sure the drill bit doesn’t wander.
There are different types of extractors, but spiral flutes are generally the most effective for most situations. You can also find straight flute extractors, which are less aggressive and can be better for softer metals or when you’re worried about over-tightening and breaking the extractor itself. Some sets come with a special drill bit that’s designed to drill the correct size pilot hole for each extractor, which is a nice touch and reduces the guesswork. I picked up a set from a reputable tool brand for about $30 a few years back, and it’s saved me countless hours of frustration. It’s one of those tools that you don’t use often, but when you need it, you really need it.
One common mistake people make is using the wrong size extractor for the screw. The set will usually have recommendations, but eyeball it too. You want an extractor that’s substantial enough to grip, but not so big that it obliterates what’s left of the screw head. And for the love of all that is holy, use a slow drill speed when you’re drilling the pilot hole and when you’re backing out the screw with the extractor. High speeds generate heat and can strip the extractor itself or, worse, break it off inside the screw, which is a nightmare scenario. A variable speed drill is a must-have for this kind of work.

When All Else Fails: The Destructive (but Effective) Methods
So, you’ve tried the rubber bands, you’ve tried the extractors, and that stupid screw is still sitting there, smugly resisting all your efforts. It’s time to get a bit more aggressive. This is where you accept that the screw is probably not going to be reusable, and your goal is simply to get it out of there.
My favorite method in this situation is cutting a new slot into the screw head. If it’s a Torx screw, and the head is raised enough, you can use a Dremel with a thin cut-off wheel or even a hacksaw blade (carefully!) to cut a straight slot across the damaged recess. This effectively turns it into a flathead screw.
Then, you can use a good quality flathead screwdriver with a firm grip to back it out.
This method requires a steady hand and some patience. You don’t want to cut too deep, or you risk cutting into the surrounding material. And you definitely don’t want to cut into the threads of the screw if you can avoid it. Once the slot is cut, use a screwdriver that fits snugly into the new slot. Apply firm downward pressure and turn slowly. This is where those impact screwdrivers can also come in handy, as the sharp rap can help the flathead bit seat properly in the new slot.
If cutting a slot isn’t an option, or the screw head is completely flush or countersunk, then you might have to resort to drilling the entire screw head off. You use a drill bit that’s slightly larger than the screw shank (the part of the screw under the head) and drill directly down through the center of the head.
The goal is to drill just deep enough to sever the head from the shank. Once the head is gone, you can lift the piece you were trying to remove. The remaining shank of the screw will still be in the other piece, and you can usually grab it with a pair of locking pliers (like Vise-Grips) and twist it out.
This is a destructive method, so make sure you’re okay with losing the screw and potentially needing to replace it with a bolt and nut or a similar workaround.
I had a situation where a small metal bracket was held on by two tiny, deeply recessed stripped Torx screws. No extractor was going to work. I ended up using a Dremel to carefully grind away the edges of the screw heads until they were basically gone, allowing me to lift the bracket. Then I was left with just the shanks, which I managed to extract with needle-nose Vise-Grips. It took forever, and I probably went through three grinding bits, but it was still faster than trying to force something that wasn’t going to work.
What Not to Do (and Why Everyone Else Is Wrong)
Let’s talk about the common advice you see online, the stuff that sounds good but often makes things worse. First off, the idea of using pliers to grip the head. Everyone says, “Just grab it with pliers and twist!” Yeah, right.
If the screw head is raised enough to get a grip, fine. But most of the time, those stripped screw heads are flush or nearly flush.
You grab them with pliers, you just round off whatever’s left of the edges, making it even harder for anything else to grip. Pliers are for gripping, not for delicate screw removal. Unless you have a pair of specialized locking pliers with very fine jaws designed for this purpose, leave the regular pliers in the toolbox.
Then there’s the ‘super glue and screwdriver’ trick. Some people swear by putting a blob of super glue on the screw head, sticking a screwdriver in, letting it dry, and then unscrewing. I’ve tried this. Maybe it works on a barely stripped screw in a very light-duty application. But for anything even remotely seized or properly stripped, the glue just crumbles, or the screwdriver spins in the glue. It’s messy, unreliable, and frankly, a waste of good super glue. Save that stuff for fixing cracked plastic or gluing your fingers together accidentally.
Another piece of bad advice is trying to use a drill on ‘reverse’ without any kind of extractor or bit. Just jamming a drill bit in there and hoping for the best is a recipe for disaster. You’re going to enlarge the hole, mangle the screw head further, and potentially damage your drill bit. If you’re going to use a drill, it needs to be in conjunction with a proper tool like a screw extractor or a cutting tool. The drill is the power source; it needs a tool to do the actual work of gripping or removing the screw. (See Also: Cant Remove Screw From Moen Faucet )
Finally, the idea that you should just keep trying harder and harder with the same tool. If your screwdriver is slipping, forcing it harder is only going to make the stripping worse. You’re basically grinding away the metal. At that point, you need to step back, assess the situation, and try a different approach. This is where people get into trouble, thinking more force will solve the problem when it’s actually a lack of the right kind of force or the right kind of tool that’s the issue. Be methodical, not just forceful.
A Real-Life Nightmare: When the Screw Head Breaks Off
This is the ultimate boss level of stripped screw problems. You’re trying to get a stubborn screw out, you’re applying what you think is the right amount of force, and suddenly… snap. The head of the screw breaks off, leaving just the threaded shank embedded in the material. This has happened to me more times than I care to admit, usually on older, rusted fasteners. The worst was on a vintage bicycle frame I was restoring. Two small Torx bolts holding a brake caliper snapped clean off. The remaining studs were tiny, maybe 3mm in diameter, and completely seized with rust.
When the head breaks off, your options become limited and often involve more destructive methods. If there’s enough of the shank sticking out, your first best bet is a pair of locking pliers (Vise-Grips). Clamp them on as tight as you can, and try to slowly twist the remaining stud counter-clockwise. This requires a lot of patience and can be difficult if the shank is really stuck or if it’s flush with the surface. I’ve had some luck with specialized internal pipe wrenches, but they’re overkill for most jobs and expensive.
If pliers won’t grip or the shank is flush or countersunk, you’re looking at drilling. This is where things get really tricky. You need to drill a pilot hole directly into the center of the broken shank. A drill press is ideal for this to make sure you’re drilling perfectly straight. If you’re using a hand drill, a center punch is absolutely key to prevent the bit from wandering. Once you have a pilot hole, you can try using a screw extractor again. However, broken-off bolts are often hardened steel, making them very difficult to drill into. You might need cobalt drill bits or even carbide bits, and you’ll have to go slow and use plenty of cutting fluid.
I once spent an entire day trying to drill out a broken bolt from a cast iron engine block. I went through three drill bits, each one dulling faster than the last. Eventually, I had to resort to using a carbide burr on a die grinder to slowly, painstakingly grind away the remaining bolt material from the inside out. It was tedious, nerve-wracking work, and I ended up with a slightly enlarged hole that I had to repair with a helicoil insert. It taught me a valuable lesson about the importance of using the right tools and techniques from the start to avoid reaching this stage.
What Is a Stripped Screw?
A stripped screw is one where the recess in the head (like the cross for a Phillips, or the star for a Torx) has been damaged or worn down so much that a screwdriver or other tool can no longer get a good grip to turn it. This usually happens when the wrong size or a worn-out screwdriver bit is used, or when too much force is applied, causing the bit to slip and grind away the metal in the recess.
Can You Fix a Stripped Screw?
Yes, you can often fix a stripped screw, but it depends on how badly it’s stripped. For minor stripping, tricks like using a rubber band or a larger screwdriver bit might work. For more severe stripping, specialized screw extractors or cutting a new slot into the screw head are usually necessary to remove it. Sometimes, the head may break off, requiring more destructive methods.
What’s the Best Tool for a Stripped Screw?
The best tool for a stripped screw depends on the severity of the stripping. For slightly stripped screws, a rubber band or a manual impact driver can work. For moderately stripped screws, screw extractors (like spiral flute extractors) are highly effective. If the head is still intact but badly damaged, cutting a new slot with a Dremel or hacksaw can turn it into a flathead screw. If the head breaks off, locking pliers or drilling out the remaining shank are options.
How Do I Remove a Stripped Torx Screw?
Removing a stripped Torx screw often requires specialized tools. First, try applying firm downward pressure with the correct size Torx bit, or even a slightly larger one if it can be seated. A rubber band between the bit and the screw head can sometimes help. If that fails, a Torx screw extractor set is the next best step, involving drilling a pilot hole and using the reverse-threaded extractor. In severe cases, you might need to cut a new slot across the damaged Torx recess with a Dremel and use a flathead screwdriver.
What If a Screw Extractor Breaks Off in the Screw?
If a screw extractor breaks off in the screw, you have a very difficult situation. The extractor itself is hardened steel, making it tough to drill out. You might need a diamond-tipped drill bit or a carbide burr on a rotary tool to carefully grind it away. Sometimes, heating the surrounding material can help expand it and loosen the broken extractor. It’s a last-ditch effort, and often requires professional help or a lot of patience and specialized tools to avoid further damage.
Conclusion
So, you’ve faced the stripped star screw, and you’re still standing. It’s frustrating, I get it. I’ve thrown tools, I’ve considered just leaving things unfinished, and I’ve definitely uttered words I wouldn’t say around my grandma. But the key is not to panic and not to keep doing the same thing that isn’t working.
Invest in a decent set of screw extractors. Seriously. It’s not a huge expense, and the amount of grief it can save you is worth ten times the price. And remember, sometimes the best solution isn’t the one that saves the screw; it’s the one that gets the job done without turning a minor annoyance into a major repair job. Don’t be afraid to get a little destructive if you have to.
You can’t get that stripped star screw out by wishing it gone. Pick the right tool, be patient, and if all else fails, embrace the Dremel. You’ve got this.
