Stripped Allen keys can be a frustrating obstacle when you’re trying to complete a project. The key may slip and damage the screw head, or it may simply refuse to turn. Fortunately, there are a few simple tricks you can try to remove a stripped Allen key without causing further damage.
First, try using a rubber band. Place the rubber band over the stripped Allen key and insert it into the screw head. The rubber band will provide extra friction, which may help you to turn the key. If that doesn’t work, try using a pair of pliers. Grip the Allen key with the pliers and try to turn it. Be careful not to apply too much pressure, or you could damage the screw head.
Finally, if all else fails, you can try using a screw extractor. Screw extractors are specially designed tools that can remove stripped screws and bolts. To use a screw extractor, first drill a small pilot hole into the center of the stripped screw head. Then, insert the screw extractor into the pilot hole and turn it counterclockwise. The screw extractor will bite into the stripped screw head and remove it.
Identifying the Stripped Allen Key
Stripped Allen keys, also known as hex keys or hex wrenches, can be a frustrating problem to encounter, especially when you’re in the middle of a project. Stripped Allen keys can occur due to various reasons, such as applying excessive force, using the wrong size key, or encountering a key made from low-quality material. Regardless of the cause, identifying a stripped Allen key is crucial to determine the best course of action.
There are several telltale signs that can help you identify a stripped Allen key:
Visual Inspection: Visually examine the Allen key’s tip. If the edges of the hex head are worn or rounded, it may indicate stripping. Additionally, check for any nicks or burrs on the sides of the key, as these imperfections can interfere with a proper fit.
Resistance Test: Insert the Allen key into the screw head and try to turn it. If the key slips or spins freely without engaging with the screw, it’s likely stripped. A stripped key will not provide enough grip to tighten or loosen the screw effectively.
Size Compatibility: Compare the Allen key to the screw head. If the key is too small or too large, it can cause stripping. Ensure that you’re using the correct size key for the specific screw. It’s recommended to have a set of Allen keys in various sizes to accommodate different screw heads.
Selecting the Right Extraction Method
When choosing an extraction method, consider the severity of the stripping, available tools, and your comfort level. Here are some options:
1. Manual Extraction
Use pliers or tweezers to grip the screw’s head or exposed Allen key. Turn counterclockwise with firm, even pressure to release the screw. This method is suitable for lightly stripped screws in accessible locations.
2. EZ-Out Extractor Tool
An EZ-Out extractor tool is specifically designed to remove stripped and broken Allen keys. Its conical shape and high-quality steel allow it to bite into the remaining keyhole and create a reverse thread. Insert the extractor tool into the keyhole, apply slight pressure, and turn counterclockwise. As the extractor engages, it will bite deeper and loosen the screw.
For best results:
- Select the correct extractor size for the screw.
- Insert the extractor securely into the keyhole.
- Apply steady pressure and turn counterclockwise.
- Avoid overtightening or forcing the extractor.
| Pros | Cons |
|---|---|
| Effective on severely stripped screws | Requires a specialized tool |
| Minimal damage to surrounding area | May not be suitable for small or deep keyholes |
Using an Allen Key Extractor
An Allen key extractor is a specialized tool designed to remove stripped or damaged Allen bolts and screws. It is typically made of hardened steel and features a tapered end that fits into the stripped bolt head. The extractor is then turned using a wrench or socket, which engages with the tapered end and gradually loosens the bolt.
1. Choose the right extractor.
Allen key extractors come in a variety of sizes to accommodate different bolt sizes. It is important to select an extractor that is slightly smaller than the inside diameter of the stripped bolt head. If the extractor is too large, it will not fit into the head properly and will not be able to engage with the bolt.
2. insert the extractor.
Once you have selected the correct extractor, insert it into the stripped bolt head. The tapered end should fit snugly into the head. Use a wrench or socket to turn the extractor counterclockwise, which will begin to loosen the bolt.
3. Apply downward pressure.
As you turn the extractor, be sure to apply downward pressure to keep it securely in the bolt head. This will help to prevent the extractor from slipping and will increase the chances of successfully removing the bolt. If the bolt is particularly stubborn, you may need to tap the extractor lightly with a hammer to help loosen it.
4. Remove the bolt.
Once the bolt has been loosened, use a wrench or socket to remove it completely. Be careful not to overtighten the extractor, as this could damage the bolt or the extractor itself.
| Pros | Cons |
|---|---|
|
– Effective at removing stripped bolts – Relatively inexpensive – Easy to use |
– Can damage the bolt if overtightened – May not be effective on all types of stripped bolts |
Leveraging a Screw Extractor
A screw extractor is a specialized tool designed to remove stripped screws and bolts. It features a hardened steel tip that bites into the damaged screw, providing a secure grip. To use a screw extractor:
- Select an extractor that is slightly smaller than the damaged screw.
- Drill a pilot hole into the screw head. The hole should be deep enough to accommodate the extractor’s tip.
- Insert the extractor into the pilot hole and turn it clockwise using a wrench or screwdriver.
- As the extractor bites into the screw, it will create a reverse thread, gradually loosening the screw.
- When using a screw extractor, there are several important tips to follow:
- Apply downward pressure to the extractor while turning it.
- If the extractor does not budge, try soaking the screw in penetrating oil for a few hours.
- Use a high-quality extractor made from durable steel.
- Avoid using excessive force, as this can damage the extractor or the surrounding material.
- If the screw is particularly stubborn, consider using a combination of methods, such as using a screw extractor in conjunction with heat or vibration.
Utilizing an Impact Screwdriver
An impact screwdriver can be an effective tool for removing stripped Allen key. Here’s how to use it:
1. Choose an impact screwdriver bit that is slightly smaller than the stripped Allen key. This will help to bite into the key and create more friction.
2. Insert the impact screwdriver bit into the stripped Allen key and hold it in place.
3. Apply pressure to the impact screwdriver and engage the hammering action.
4. Continue applying pressure and hammering until the stripped Allen key starts to turn.
5. Once the Allen key starts to turn, continue applying pressure until it is completely removed.
6. If the Allen key is still stuck, try using a different impact screwdriver bit or increasing the pressure.
7. **Additional Tips for Using an Impact Screwdriver to Remove Stripped Allen Keys**:
Use a Penetrating Oil
If the Allen key is heavily corroded or rusted, apply a penetrating oil to the joint and let it sit for a few minutes. This will help to loosen the key and make it easier to remove.
Use a Reverse Impact Setting
Some impact screwdrivers have a reverse impact setting. This setting can be helpful for removing stripped Allen keys because it applies force in the opposite direction of the normal impact setting. This can help to loosen the key and make it easier to remove.
Use a Hammer and Punch
If you don’t have an impact screwdriver, you can try using a hammer and punch to remove a stripped Allen key. Place the punch on the edge of the Allen key and tap it with a hammer. This will help to break the seal between the key and the screw and make it easier to remove.
Preventing Stripped Allen Keys in the Future
