How To Remove A Stripped Screw With A Screwdriver
To remove a stripped screw with a screwdriver, your primary goal is to create new grip or increase friction. Start by using a larger flathead screwdriver if the screw head allows, or try placing a rubber band over the screw head before inserting your driver. If that fails, consider methods like tapping the screwdriver with a hammer, applying a penetrating oil, or using specialized tools like a screw extractor or locking pliers.
Always wear appropriate safety gear, such as eye protection and gloves, and select the right tool for the job to avoid further damage to the screw or surrounding material.
Picture this: You’re in the middle of a project, maybe disassembling an old piece of furniture, replacing a light fixture, or just trying to fix a loose cabinet hinge. Everything’s going smoothly until you encounter that screw. You push, you twist, you grunt, and then it happens – the dreaded “cam-out.” The screwdriver slips, grinding away the crisp edges of the screw head, leaving you with a smooth, round, or mangled mess.

Understanding Why Screws Strip and How to Prevent It
Before we dive into removal, let’s quickly understand why screws strip in the first place. Knowing the cause can help you prevent it on future projects.
Common Causes of Stripped Screw Heads
- Wrong Screwdriver Bit: Using a Phillips head driver in a Pozidriv screw, or a too-small flathead, is a common culprit.
- Excessive Torque: Overtightening can shear the screw head or strip the recess.
- Worn-Out Bits: Old, rounded-off screwdriver bits lose their grip.
- Soft Metal Screws: Some screws are made from softer metals that are more prone to stripping.
- Angle of Attack: Driving a screw at an angle can cause the bit to slip and damage the head.
- Rusted or Seized Screws: Corrosion can make a screw incredibly difficult to turn, leading to stripping when force is applied.
Prevention is Key
A little foresight can save a lot of headaches. Always choose the correct driver bit for the screw type and size. Apply firm, steady pressure, keeping the bit perpendicular to the screw head. If a screw feels tight, consider a pilot hole or a bit of lubricant.
Initial Assessment: Can You Still Use a Screwdriver?
When you first encounter a stripped screw, take a moment to assess the damage. Is the recess completely rounded out, or is there still some purchase left? This initial evaluation will help you choose the best removal method.
Examining the Screw Head
Look closely at the screw head. Can you see any remaining edges or corners within the recess? Sometimes, a screw is only partially stripped, meaning a regular screwdriver might still work with a little modification.
Selecting the Right Screwdriver
If there’s still some recess, ensure you’re using the absolute best-fitting screwdriver. Sometimes, a slightly larger flathead can wedge into a partially stripped Phillips or Torx head, offering just enough grip.
Basic Techniques: How to Remove a Stripped Screw with a Screwdriver
These methods focus on increasing the friction or bite between your existing screwdriver and the damaged screw head. They are often the first line of defense for a DIYer.
The Rubber Band Trick
This is a classic for a reason. Place a wide rubber band (or even a piece of rubber glove) flat over the stripped screw head. Then, insert your screwdriver firmly into the screw, pushing through the rubber. The rubber band fills the stripped void, providing extra grip for your screwdriver. Apply steady, downward pressure and slowly turn the screw counter-clockwise.
Using a Wider Flathead Screwdriver
For Phillips or square drive screws with a slightly rounded-out recess, a flathead screwdriver can sometimes be a lifesaver. Choose a flathead that is just wide enough to wedge into two opposing points of the stripped recess. You’re essentially creating a new, albeit shallow, slot. Apply significant downward pressure and slowly twist.
Hammer and Screwdriver Technique
Sometimes, a little percussive maintenance is all it takes. This method works by seating the screwdriver deeper into the screw head, potentially creating new purchase. Place the appropriate screwdriver bit (or a flathead) into the stripped screw head. Gently tap the end of the screwdriver with a hammer. This drives the bit deeper, reforming the metal of the screw head slightly. After a few taps, apply firm downward pressure and try to turn the screw. This can be especially effective for screws in wood.
Adding Abrasive Material for Grip
Similar to the rubber band, you can try adding a small amount of abrasive material to the screw head. Fine valve grinding paste or even steel wool can provide additional friction. Apply a tiny dab to the screw head, insert your screwdriver, apply firm pressure, and twist.
When a Screwdriver Isn’t Enough: Moving to More Robust Tools
If the screwdriver-based methods don’t work, it’s time to bring in the big guns. These tools are designed to grip, cut, or drill out stubborn fasteners.
Using Vise Grips or Locking Pliers
If the screw head is proud (sticks out above the surface), locking pliers or vise grips are your best friend. Clamp the jaws firmly onto the screw head. The tighter the grip, the better. Once locked, twist the pliers counter-clockwise to rotate the screw. This is often the most effective method for screws that aren’t flush with the surface.
Screw Extractors (Easy-Outs)
A screw extractor set is an essential tool for any serious DIYer. These specialized bits are designed to bite into stripped or broken screws.
- Drill a Pilot Hole: Using a drill bit slightly smaller than the extractor, drill a pilot hole into the center of the stripped screw head.
- Insert Extractor: Select the appropriately sized screw extractor. It will have a reverse (left-hand) thread.
- Extract: Insert the extractor into the pilot hole and, using a tap handle or a drill on a very slow reverse setting, turn the extractor counter-clockwise. As it turns, it will bite into the screw and, ideally, back it out.
Always start with the smallest extractor that will fit the pilot hole you can safely drill.
Dremel Tool with a Cutting Wheel
For screws with a completely rounded-out head that are flush with the surface, a rotary tool like a Dremel with a thin cutting wheel can create a new slot.
- Safety First: Wear eye protection and gloves.
- Cut a Slot: Carefully cut a new, deep slot across the diameter of the screw head.
- Extract: Once the slot is cut, you can use a large flathead screwdriver to remove the screw. Be extremely careful not to damage the surrounding material.
This method works particularly well on metal or composite materials where the screw head is accessible.
Drilling Out the Screw Head
This is a last resort, as it will destroy the screw and potentially damage the surrounding material if not done carefully.
- Center Punch: Use a center punch to create a divot in the middle of the stripped screw head. This prevents the drill bit from wandering.
- Choose Drill Bit: Select a drill bit slightly larger than the screw shaft (not the head).
- Drill Slowly: Using a drill, slowly and carefully drill down through the screw head. The goal is to drill off the head, allowing the material to separate.
- Remove Shaft: Once the head is off, you can usually remove the remaining screw shaft with pliers or vice grips, or drill it out completely if necessary.
This method is common in woodworking when a screw needs to be completely removed from a piece of lumber.
Advanced & Niche Techniques for Tough Cases
Sometimes, a screw is so stubborn or rusted that standard methods just won’t cut it. These techniques require a bit more finesse or specialized materials.
Penetrating Oil for Rusted Screws
For screws that are seized due to rust or corrosion, penetrating oil is a must. Apply a generous amount to the screw head and threads. Let it sit for at least 15-30 minutes, or even overnight for very stubborn cases. The oil will wick into the threads, breaking down rust and lubrication. After soaking, try one of the other removal methods.
Impact Driver
An impact driver (not an impact wrench) delivers a powerful rotational and downward force simultaneously. This can be incredibly effective for breaking loose stubborn or partially stripped screws. Ensure you have the correct bit and apply firm, steady pressure. The “impact” action helps to seat the bit and jar the screw loose without stripping it further.
Welding a Nut Onto the Screw Head (Metalworking)
For metalworkers and welders, this is a highly effective, albeit more advanced, method. If the screw head is completely rounded or broken, you can weld a nut onto the remnants of the screw head. The heat from welding can also help break the bond of rust or threadlocker. Once the nut is securely welded, you can use a wrench to turn and remove the screw. This method is particularly useful when working with automotive parts or structural metal components.
Epoxy or Super Glue for Maximum Grip
If the screw head is very shallow and stripped, and you don’t mind sacrificing the screwdriver, you can try gluing the screwdriver bit into the screw head.
- Clean Surfaces: Ensure the screw head and screwdriver bit are clean and free of grease.
- Apply Adhesive: Apply a strong epoxy or super glue into the stripped screw recess and onto the tip of your screwdriver bit.
- Join and Cure: Insert the screwdriver bit firmly into the screw head. Allow the adhesive to cure completely (this can take several hours for epoxy).
- Twist: Once cured, you should have a solid connection. Carefully twist the screwdriver to remove the screw.
This is a “one-shot” method, as you’ll likely damage the screwdriver bit.
Safety First: Essential Precautions
Working with stripped screws can be challenging, and safety should always be your top priority. Accidents happen quickly, especially when dealing with stubborn fasteners and powerful tools.
Always Wear Eye Protection
When drilling, grinding, or using an impact driver, small metal fragments can fly off. <Safety glasses> are non-negotiable. They protect your eyes from debris that could cause serious injury.
Protect Your Hands
Gloves can prevent cuts, scrapes, and blisters, especially when dealing with sharp edges or hot metal. They also provide a better grip on tools.
Secure Your Workpiece
Whenever possible, clamp your workpiece firmly to a workbench or hold it securely in a vise. This prevents it from shifting, reducing the risk of slipping tools and injury. It also gives you better leverage and control.
Use the Right Tool for the Job
Don’t force a tool that isn’t working. Using the wrong tool can lead to further damage to the screw, the material, or even yourself. For instance, using a drill bit not designed for metal on a metal screw will dull the bit and make the job harder.
Take Your Time
Rushing often leads to mistakes. Be patient, especially with stubborn screws. Apply steady pressure and work slowly. If a method isn’t working, stop, reassess, and try a different approach.
Frequently Asked Questions About How to Remove a Stripped Screw with a Screwdriver
What is the easiest way to remove a stripped screw?
The easiest way often depends on the severity of the strip. For minor stripping, try the rubber band trick or a larger flathead screwdriver. If the head is proud, vise grips are usually the quickest solution. For a completely recessed and stripped head, a screw extractor is generally the most reliable method.
Can WD-40 help remove a stripped screw?
WD-40 is primarily a water displacement and light lubricant. While it can help with minor rust, a dedicated penetrating oil (like PB Blaster or Liquid Wrench) is far more effective at breaking down rust and seizing, making it easier to remove a stripped screw. Apply penetrating oil and let it soak for a while before attempting removal.
What if the screw head breaks off entirely?
If the screw head breaks off, you’ll need to remove the remaining shaft. If it’s protruding, use vise grips or locking pliers. If it’s flush or recessed, a screw extractor is your best bet. Drill a pilot hole into the center of the remaining shaft and use a left-hand threaded extractor to back it out. In some cases, you might need to drill out the entire shaft.
Can I use super glue to remove a stripped screw?
Yes, you can use strong super glue or epoxy to glue a screwdriver bit into a severely stripped screw head. Clean both surfaces thoroughly, apply the adhesive, press the bit firmly into the screw, and allow it to cure completely. This is a last-resort method, as it will likely sacrifice the screwdriver bit.
How do I prevent screws from stripping in the future?
Prevention is key! Always use the correct size and type of screwdriver bit for the screw. Apply firm, consistent downward pressure while turning, ensuring the bit is fully seated. Avoid over-tightening. For stubborn or soft screws, drill appropriate pilot holes and consider using a drill with a clutch setting to prevent stripping.
