How to Remove a Broken Screw: Step-by-Step Guide
A broken screw can bring your DIY project or home repair to a halt in seconds. Whether the screw snapped during installation or is rusted in place, extracting it doesn’t have to mean hours of frustration. With the right tools and methods, you can successfully remove even the most stubborn broken screws and get your project back on track.
Below, you’ll find practical methods, tips, and advice on how to remove a broken screw, including recommended tools, cost-saving hacks, and troubleshooting for challenging cases.
Clear Answer: What is the Tool to Remove a Broken Screw?
The primary tool used to remove a broken screw is a screw extractor. This specialized tool is designed with a reverse (left-handed) thread that bites into the broken screw shaft, allowing you to twist it out in the opposite direction of installation.
However, screw extractors are just one option—you may also need everyday items like pliers, needle-nose vise grips, or even household hacks, depending on the situation and whether the screw head is accessible.
Step-by-Step: How to Remove a Broken Screw
Here’s a comprehensive breakdown for removing a broken screw, from basic methods to advanced solutions if the situation is more challenging.
1. Assess the Situation
Before grabbing any tools, carefully examine the broken screw:
- Is any part of the screw protruding?
- Is it headless (broken off flush with the material) or embedded?
- What material is it stuck in (wood, metal, plastic)?
- Is it rusted or just snapped off?
Understanding these factors guides which method and tools to use.
2. Basic Methods for Screws That Protrude
If part of the broken screw is sticking out above the surface, start with the simplest approaches:
Use Pliers or Locking Pliers
- Grip the exposed screw firmly with locking pliers or regular pliers.
- Slowly turn counterclockwise, applying steady pressure.
-
If the screw is stubborn, try working it back and forth gently to loosen corrosion.
-
Tip:* Needle-nose locking pliers can grip even small protrusions.
Try Gripping with a Rubber Band
Sometimes, if the screw head is damaged but not completely sheared off:
- Place a wide rubber band over the screw head.
- Press your screwdriver into the band and turn counterclockwise.
- The rubber fills stripped gaps, creating grip to help drive the screw out.
3. Removing a Headless or Embedded Broken Screw
When the screw has snapped off flush with the material or is completely embedded, you’ll need a screw extractor:
Using a Screw Extractor Kit
What You’ll Need:
– Screw extractor bit (matched to screw size)
– Power drill (with reverse setting)
– Center punch or nail
– Hammer
– Safety glasses
Steps:
-
Mark the Center:
Use a center punch and hammer to create a shallow starting point in the center of the broken screw. This prevents the drill bit from wandering. -
Drill a Pilot Hole:
Select a drill bit slightly smaller than the screw extractor. Drill straight into the center of the broken screw to a depth of 1/8–1/4 inch (3–6 mm). -
Insert the Extractor:
Place the screw extractor into the pilot hole. Set your drill to reverse (counterclockwise). -
Turn the Extractor:
Slowly start the drill or use a T-handle to twist the extractor. The left-handed threads will bite into the metal as you apply pressure. -
Remove the Screw:
Keep twisting; as the extractor bites deeper, it should grip and begin unscrewing the broken screw. -
Note:* If you don’t have an extractor kit, they are widely available online or at hardware stores, usually under $20.
4. Advanced Methods for Stubborn Screws
Some screws, especially those rusted into place or broken inside hard materials, need more drastic action.
Apply Heat
- A soldering iron held against the screw or the surrounding metal for a couple of minutes can expand the material, helping break loose rust bonds.
- Be careful with flammable materials—this is best used on metal objects only.
Tap Gently
- Sometimes, tapping the area lightly with a hammer can jar corrosion loose.
- Avoid hitting too hard, especially on wood, as it may cause cracks.
Drill Out the Screw
- If all else fails, drill through the screw with a bit the same size or slightly larger than the screw’s shaft.
- Be extremely careful to stay centered, especially in soft materials like wood, to avoid damaging the hole for a replacement screw.
- Once the screw is drilled out, you may need to fill and redrill the hole or use a larger screw.
Tips for Best Results
- Go Slowly: Rushing can make things worse—like stripping threads or damaging the surrounding material.
- Use Penetrating Oil: Applying penetrating oil or WD-40 to the area can help loosen rusted screws. Let oil soak in for at least 10–15 minutes before attempting removal.
- Choose the Right Extractor Size: Match the extractor to your screw size. Too small and it won’t grip; too large and you risk damaging the hole.
- Protect the Surface: If working on a finished surface, protect it with painter’s tape before starting extraction.
- Stay Safe: Always wear safety glasses when drilling or hammering metal.
Cost Tips & Budget-Friendly Advice
- Buy Only What You Need: Single screw extractor bits are sold individually if you’re on a budget; you don’t always need a full kit.
- Rent Tools: Many hardware stores allow you to rent specialized extractors if this is a one-off repair.
- Plan for Shipping: If ordering a screw extractor online, factor in shipping costs. Sometimes, picking up at a local hardware store is cheaper and faster.
- DIY Hacks: For minor jobs, household items (rubber bands, pliers) can often handle the problem, saving you the expense of new tools.
Common Challenges & How to Overcome Them
Broken Screw Won’t Budge
- Apply more penetrating oil and let it sit.
- Try tapping around the area gently with a hammer, then retry extraction.
Screw Head or Slot is Stripped
- Use a rubber band or cut a new slot for a flathead screwdriver using a rotary tool if accessible.
No Access to the Broken Screw (Deeply Embedded)
- Drill and extract with specialty extractors for headless screws.
- Consider plugging and redrilling if extraction fails, especially in wood projects.
Worried About Damaging the Material
- Start with the least invasive methods.
- Use protective tape over visible surfaces before working.
Practical Tips and Best Practices
- Organize Tools First: Have pliers, extractors, drills, and safety gear ready before you start.
- Test Extractors on Scrap: If you’re new to these tools, try practicing on a scrap piece first to get a feel for the process.
- Replace with Better Hardware: After removal, use high-quality screws to prevent recurring issues.
- Document the Process: For complex projects, take photos before and after for easy reference and to track progress.
Conclusion
Removing a broken screw may seem like a daunting task, but with the right approach and a bit of patience, you can tackle almost any scenario. Start with the simplest solutions—using pliers or a rubber band—before moving on to specialized screw extractor kits for more stubborn or embedded screws. Don’t forget key safety tips, and consider budget-saving measures if you’re handling a one-time repair. Restore your project and your peace of mind with these methods!
Frequently Asked Questions (FAQs)
1. What is a screw extractor, and do I really need one?
A screw extractor is a tool specifically designed for removing broken, stripped, or embedded screws. It features a reverse-threaded bit that digs into the damaged screw, allowing you to twist it out. While not always necessary for every job, a screw extractor is invaluable when pliers or simple tricks don’t work.
2. What if the broken screw is rusted and stuck fast?
Apply a generous amount of penetrating oil to the area and let it soak in for 10–15 minutes (or longer for old, rusted screws). Heating the area with a soldering iron or heat gun (on metal only) can also help break corrosion bonds, making extraction easier.
3. Can I use everyday household items to remove a broken screw?
Yes! For screws with part exposed, locking pliers or even regular pliers might grip well enough to turn them out. A thick rubber band under your screwdriver can help remove screws with worn or stripped heads. However, for fully embedded or headless screws, a proper extractor is best.
4. What should I do if the extractor doesn’t work or breaks?
If an extractor fails or itself breaks off in the screw, you might have to drill out both the broken extractor tip and the screw. Use a cobalt drill bit for hardened steel. Occasionally, filling the hole and redrilling a new pilot hole for a replacement screw may be the only viable solution.
5. How do I prevent screws from breaking in the future?
- Pre-drill the correct-sized pilot hole before driving in screws.
- Use the right type and size of screw for your material.
- Avoid over-tightening, and use a screwdriver or driver bit that fits snugly.
- Lubricate screws with wax or soap for tough or hardwoods.
Armed with these tips and methods, you can tackle broken screw removal projects with confidence and skill!
