Stripped or broken screws can be a major headache, but there’s no need to panic. With the right tools and a little know-how, you can easily remove them using a screw extractor. Screw extractors are specially designed tools that grip the damaged screw and allow you to remove it. They come in a variety of sizes and shapes to accommodate different types of screws. In this article, we’ll provide you with a step-by-step guide on how to use a screw extractor to remove a stripped or broken screw.
Before you begin, you’ll need to gather a few tools. You’ll need a screw extractor that is the appropriate size for the screw you’re trying to remove. You’ll also need a drill, a drill bit that is slightly smaller than the screw extractor, and a pair of pliers. Once you have your tools, you can begin the process of removing the screw. First, use the drill to create a pilot hole in the center of the screw. The pilot hole should be just deep enough to accommodate the screw extractor. Next, insert the screw extractor into the pilot hole and use the pliers to turn it counterclockwise. As you turn the screw extractor, it will grip the damaged screw and begin to remove it. Continue turning the screw extractor until the screw is completely removed.
If you’re having trouble removing the screw, you can try applying a penetrating oil to the screw. Penetrating oil will help to loosen the screw and make it easier to remove. You can also try using a heat gun to heat the screw. Heating the screw will help to expand the metal and make it easier to remove. Once the screw is removed, you can replace it with a new screw. Be sure to use a screw that is the same size and type as the original screw. You can also use a thread locker to help prevent the new screw from becoming stripped or broken.
Employing the Screw Extractor Safely
To ensure a safe and effective screw extraction, adhere to the following guidelines:
1. Appropriate Screw Extractor Selection
Choose the correct screw extractor size and type that matches the damaged screw.
2. Prepare the Screw
Drill a pilot hole into the center of the screw using a bit that is slightly smaller than the extractor’s inner diameter. This will help guide the extractor and prevent it from slipping.
3. Grip Firmly
Securely hold the extractor with a pair of locking pliers to prevent it from accidentally slipping off the screw.
4. Apply Reverse Force
Turn the extractor counterclockwise to loosen the screw. Apply steady and gentle pressure to avoid damaging the extractor or surrounding materials.
5. Remove the Extractor
Once the screw is completely loosened, carefully pull the extractor straight out of the screw hole. If the extractor is stuck, apply a penetrating lubricant around the screw and extractor to aid in removal. Use a pair of needle-nose pliers to grip the extractor’s notched end if necessary.

Alternative Techniques for Stubborn Screws
Center Punch
Employ a center punch to create a tiny indentation in the center of the screw. This provides a precise starting point for the drill that helps prevent slipping.
Rubber Band
Place a rubber band over the screw and try to turn it using a screwdriver or wrench. The increased friction between the rubber and screw can assist in loosening it.
Heat
Gently apply heat around the screw using a heat gun or lighter. The expansion caused by the heat can weaken the bond between the screw and the surface.
Penetrating Oil
Apply a penetrating oil, such as WD-40 or penetrating lube, to the screw. Allow it to penetrate for several minutes before attempting to remove the screw.
Extractor Bits
Use an extractor bit specifically designed for removing damaged or stripped screws. The reverse threads of the extractor bit can often grip the screw and remove it.
Easy Out Tools
Insert an Easy Out tool into the screw and tap it lightly with a hammer to embed it. Then, use a wrench or screwdriver to turn the tool, which will gradually remove the screw.
Screw Grabber
Attach a screw grabber to the drill and insert it into the screw. Turn the drill in reverse to engage the grabber’s teeth with the screw and remove it.
Bolt Extractor
Weld a nut onto the stripped bolt head using a bolt extractor. Then, use a wrench to turn the nut and remove the bolt.
How to Use a Screw Extractor
A screw extractor is a tool used to remove broken or stripped screws. It is typically made of hardened steel and has a tapered end that fits into the screw head. The extractor is then turned counterclockwise to remove the screw. Here are the steps on how to use a screw extractor:
- Choose the right size extractor. The extractor should be slightly smaller than the screw head. If the extractor is too large, it will not fit into the screw head and will not be able to grip it. If the extractor is too small, it will not be able to generate enough torque to remove the screw.
- Drill a pilot hole. Using a drill bit that is slightly smaller than the extractor, drill a pilot hole into the center of the screw head. The pilot hole will help to guide the extractor and prevent it from slipping.
- Insert the extractor. Insert the extractor into the pilot hole and turn it counterclockwise. Apply downward pressure as you turn the extractor to help it grip the screw.
- Remove the screw. Once the extractor has gripped the screw, continue to turn it counterclockwise until the screw is removed.

How do you use a screw extractor on a stripped screw?
A screw extractor can be used on a stripped screw by following the steps outlined above. However, it is important to note that using a screw extractor on a stripped screw is more difficult than using it on a broken screw. This is because the stripped screw does not have a head for the extractor to grip onto. As a result, it is important to use a screw extractor that is specifically designed for stripped screws.
