How Does A Screw Extractor Work: Everything You Need to Know
If you work with screws a lot, you need a tool called a screw extractor. It helps you remove screws that are stripped or broken and can’t be taken out with regular tools. When you have a tough screw to remove, knowing how to use a screw extractor can save you time and make it easier.
A screw extractor is a tool that helps you take out screws that are stuck or broken. You put it in the hole where the screw is and turn it, and it holds onto the screw so you can pull it out. Screw extractors come in different shapes and sizes to fit different kinds of screws.
People use screw extractors a lot for DIY projects, fixing cars, and building things. They’re especially useful when you have an old or rusty screw that won’t come out easily. If you learn how to use a screw extractor, you’ll know you have the right tool for the job and can use it correctly.
Types of Screw Extractors
There are different types of screw extractors you can find in the market. Some popular ones are:
- Spiral-fluted screw extractors are the most common and work well with most screw sizes. They can grab and pull out the screw due to their spiral shape.
- Double-ended screw extractors have two ends, one for removing the screw and the other for making a small hole in it. They are useful for taking out screws in hard-to-reach places.
- Straight flute screw extractors are good for removing screws that are near the surface of the material. They work by drilling a hole in the screw and then pulling it out.
- Fluted screw extractors have a fluted shape that helps to keep them from slipping while removing a screw. They work well with larger screws.
What is An Easy Out Screw Extractor
An easy-out screw extractor is a tool used to remove damaged or stripped screws from an object. It has a spiral-shaped body that can fit into a drill or be operated manually with a T-handle. To remove the damaged screw, the spiral body is placed on the screw and turned counterclockwise to pull it out. Easy-out screw extractors are made of strong materials like high-speed steel or cobalt steel and come in different sizes to fit various screw sizes.
Choosing the Right Type of Screw Extractor for Your Needs
When you want to choose a screw extractor, consider the size, type, and material of the screw you want to remove. Spiral flute screw extractors can handle most screw sizes and types. Straight Flute Screw Extractors are good for screws that are close to the surface, while Double-Ended Screw Extractors are great for hard-to-reach screws. Fluted screw extractors are best for large screws, but may not work well for smaller screws.
How a Screw Extractor Works
To remove a stripped or broken screw, a tool called a screw extractor is used. Here are the steps to use one:
- First, drill a small hole in the center of the damaged screw. Make sure the hole is smaller than the screw extractor but big enough for its tip.
- Next, insert the screw extractor into the hole, making sure it’s parallel to the material’s surface and fits tightly.
- Now, turn the screw extractor anticlockwise while applying downward pressure. The extractor will grip the inside of the damaged screw and start to release it.
- Keep turning the screw extractor anticlockwise until the broken screw is completely removed from the hole. If the screw doesn’t come out easily, apply more pressure while turning the extractor.
Selecting the Right Size Screw Extractor
To remove a damaged or stripped screw correctly, you need to choose the right size screw extractor. Measure the diameter of the screw shank using a ruler or a calliper to know the correct size. The diameter of the screw extractor you choose should be equal to or a bit larger than the screw shank. If the extractor is too small, it won’t grip the screw properly, and if it’s too big, it could make the problem worse. Remember that screw extractor come in different sizes, so it’s better to have a set of them to ensure that you have the right tool for the job.
Tips for Properly Using a Screw Extractor
When using a screw extractor, it’s important to be careful and have some skill. If the pilot hole is too big, the extractor may not work well. Using too much force can damage the extractor or the material. Always use the right size extractor and follow the instructions carefully. With practice, anyone can learn to use a screw extractor to remove difficult screws.
Factors to Consider When Using a Screw Extractor

Condition of Screw
Rusty or corroded screws may need a stronger extractor.
Tips to Remove Screws Without Harming the Material
Use Correct Technique
Turn the extractor anticlockwise gently while applying constant pressure to avoid breaking the workpiece or the extractor.
Use Lubricant
Apply some WD-40 or other lubricants to make the screw easier to remove.
Pick the Right Extractor
Choose the right size and type of extractor for the job.
Gently Drill Pilot Hole
Use little pressure and a steady hand to drill a straight and centered pilot hole.
By following these tips, you can remove difficult screws without harming the workpiece or the extractor.
