Have you ever encountered a stripped Allen screw that refuses to budge, leaving you feeling frustrated and stuck? If so, you’re not alone. Stripped screws are a common annoyance, especially when working with older or heavily used machinery. However, there are several effective techniques you can employ to remove a stripped Allen screw without causing further damage. Whether you’re a seasoned mechanic or a DIY enthusiast, learning how to handle these stubborn screws will save you time and effort in the long run.
The first step in removing a stripped Allen screw is to determine the extent of the damage. If the screw head is only slightly stripped, you may be able to use a standard Allen key with a little extra force. However, if the screw head is severely stripped, you will need to use a more specialized tool. One option is to use an Allen key with a larger size than the screw head. This will provide more grip and leverage, allowing you to break the screw loose. Another option is to use an extractor bit, which is a specially designed tool that grips the screw head and allows you to remove it. In some cases, you may even need to use a pair of locking pliers to grip the screw head and unscrew it.
Once you have selected the appropriate tool for the job, it’s time to remove the stripped Allen screw. If you are using a larger Allen key or an extractor bit, simply insert the tool into the screw head and apply force until the screw loosens. Be sure to apply pressure straight down on the tool to avoid stripping the screw head further. If you are using locking pliers, carefully grip the screw head with the pliers and apply pressure until the screw loosens. Be careful not to apply too much pressure, as this could damage the screw or the surrounding material.
The Tools You’ll Need
Stripped Allen screws can be a frustrating problem, but with the right tools and a little patience, they can be removed. Here’s what you’ll need:
1. Reverse drill bit: Also known as a left-handed drill bit, this specially designed bit can help loosen stuck screws by rotating in the opposite direction. Choose a bit that is slightly smaller than the diameter of the Allen screw you’re trying to remove.
Here’s a table summarizing the different types of reverse drill bits and their recommended uses:
| Bit Type | Recommended Use |
|---|---|
| Standard Left-Handed Drill Bit | General purpose use for most screw sizes and materials |
| Extractor Bit | Designed to remove damaged or stripped screws |
| Screw Extractor Socket | Used with a socket wrench for additional torque |
| Impact-Rated Left-Handed Drill Bit | For use with impact drivers on high-torque applications |
2. Allen wrench: A standard Allen wrench set will typically include a variety of sizes and shapes. Choose the wrench that fits snugly into the Allen screw you’re trying to remove.
3. Hammer: A small hammer can be used to tap the Allen wrench into the screw and to help break the screw loose.
4. Penetrating oil: Applying penetrating oil to the screw can help loosen any rust or corrosion that may be hindering its removal.
5. Pliers: A pair of pliers can be used to grip the screw and turn it if it’s too loose for the Allen wrench to grip.
6. Safety glasses: Always wear safety glasses when working with tools to protect your eyes from flying debris.
Hammering a Flathead Screwdriver
This method involves driving a flathead screwdriver into the stripped screw head and using the screwdriver as a lever to turn the screw.
Step 1: Choose the Right Screwdriver
Select a flathead screwdriver slightly wider than the screw head. This will ensure a snug fit and minimize slippage.
Step 2: Position the Screwdriver
Place the screwdriver tip in the stripped screw head, ensuring it is seated securely and parallel to the screw.
Step 3: Hammer the Screwdriver
Using a hammer, gently tap the screwdriver’s handle. This will force the screwdriver into the screw head, creating a new gripping surface.
Step 4: Turn the Screw
Once the screwdriver is seated, use it as a lever to turn the screw. Apply steady pressure and continue tapping the handle if necessary. The screw should gradually loosen as you apply force.
Step 5: Remove the Screw
Once the screw is loose, continue turning it with the screwdriver until it can be removed by hand.

Welding a New Head on the Screw
If the screw is accessible, you can weld a new head onto it. This is a more permanent solution than using an extractor, but it requires some specialized equipment.
Materials you’ll need:
- Welder
- Welding rod
- Safety glasses
- Gloves
Steps:
- Clean the area around the screw to remove any dirt or debris.
- Place the welder on the screw head and weld a new head onto it.
- Allow the weld to cool completely.
- Use a wrench to remove the screw.
Tips:
- Use a low-heat setting on the welder to avoid damaging the screw.
- Weld for a short period of time, then allow the weld to cool. Repeat this process until the new head is secure.
- If you don’t have a welder, you can take the screw to a welding shop and have them weld a new head onto it for you.
Here is a table summarizing the steps involved in welding a new head on a screw:
| Step | Description |
|---|---|
| 1 | Clean the area around the screw. |
| 2 | Place the welder on the screw head and weld a new head onto it. |
| 3 | Allow the weld to cool completely. |
| 4 | Use a wrench to remove the screw. |
Calling a Professional
If you’ve exhausted all other options and the stripped screw remains stuck, it’s time to call in a professional. Locksmiths, hardware store employees, and skilled handymen can often remove stripped screws with specialized tools and techniques. While this may cost money, it’s a quick and reliable way to solve the problem. Some professionals may also offer non-invasive methods like screw extractors or chemical solvents to avoid damaging surrounding materials.
Here’s a table summarizing the approximate cost of professional screw removal:
| Professional Type | Average Cost |
|---|---|
| Locksmith | $50-$150 |
| Hardware Store Employee | $10-$30 |
| Handyman | $20-$60 |
When choosing a professional, look for someone who has experience with stripped screw removal and positive reviews online. It’s also important to inquire about their methods and ensure they have the appropriate tools for the job.
How To Remove A Striped Allen Screw
A stripped Allen screw can be a frustrating problem, but it’s one that can be solved with a little patience and the right tools. Here’s a step-by-step guide on how to remove a stripped Allen screw:
- Use a rubber band. Place a rubber band over the screw and try to turn it. The rubber band will provide extra grip and help you to turn the screw.
- Use a screw extractor. A screw extractor is a tool that is specifically designed to remove stripped screws. Screw extractors come in a variety of sizes, so be sure to choose one that is the right size for your screw.
- Drill out the screw. If the other methods don’t work, you can try drilling out the screw. Use a drill bit that is slightly smaller than the screw, and drill a hole into the center of the screw head. Be careful not to drill too deep, as you could damage the threads in the hole.

Can I use pliers to remove a stripped Allen screw?
Yes, you can use pliers to remove a stripped Allen screw, but be careful not to damage the screw head. Grip the screw head with the pliers and try to turn it. If the screw is too tight, you can try using a pair of locking pliers.
What is the best way to prevent Allen screws from stripping?
The best way to prevent Allen screws from stripping is to use the correct size Allen wrench and to apply the correct amount of torque. When tightening an Allen screw, start by hand-tightening the screw until it is snug. Then, use an Allen wrench to tighten the screw an additional 1/4 to 1/2 turn.
