Removing a screw from an electric screwdriver can be a challenging task, especially when dealing with rusted or tightly fastened screws. Several techniques can be employed to successfully remove the screw. One common method is to use a spanner or a wrench to gain additional leverage and force when turning the screwdriver. This can be achieved by identifying the flat bit at the base of the screwdriver handle and using an open-ended spanner that fits securely onto this flat section. Another approach involves using a hammer to gently tap the back of the screwdriver while it is positioned on the screw, helping to loosen the screw's grip. Additionally, some individuals suggest using a strong magnet to attract and extract the screw, particularly if it is small and lodged in a tight space. In certain cases, applying adhesives, such as super glue or epoxy, to the screw and then pulling it out with a dowel or similar object after the glue has dried can be effective. It is important to exercise caution when using this method to avoid getting glue in unwanted areas. For stubborn screws, applying heat and penetrating oil can aid in loosening the screw, making it easier to remove.

What You'll Learn
Using a spanner and screwdriver simultaneously
If you are dealing with a stubborn screw that is stuck in your electric screwdriver, there are a few methods you can try to remove it. One way is to use a spanner and screwdriver simultaneously.
Firstly, identify the type of screw you are dealing with. If it is a Philips head screw, try inserting a flat-head screwdriver. This technique often works best when combined with a friction-enhancing material like a rubber band. Place the rubber band over the head of the screw and then insert the screwdriver. Apply pressure and slowly turn the screw. Be careful not to turn it too fast, as this could damage the rubber band. If you don't have a rubber band, you can use other materials such as steel wool or abrasive powder.
Now, for the spanner and screwdriver technique. Most screwdrivers have a flat bit at the base of the handle, where it meets the metal. This flat bit is designed to fit an open-ended spanner. Place the spanner on this flat bit and push the end of the screwdriver handle into the screw head with your palm. With your other hand, turn the spanner, applying more force as needed. The longer the spanner, the more twisting force you will be able to apply.
If you are having trouble getting enough force, try tightening the screw a tiny bit first, and then attempt to undo it. You can also try hitting the back of the screwdriver with a hammer to loosen the screw before attempting to turn it.
Remember to always use the correct type and size of screwdriver for the screw you are dealing with. Applying too much pressure with an electric screwdriver can also contribute to screws getting stuck, so be sure to avoid this in the future.

Using a strong magnet
Firstly, it is important to select an appropriate magnet. Neodymium magnets are recommended due to their strong magnetic force. You can find these magnets at any hardware store, either as individual magnets or as part of a screwdriver magnetizer tool. Ensure the magnet has a pull force of at least 1/4 to 1 pound to effectively attract and hold the screw.
Before using the magnet, clean the screwdriver and screw bit with a rag to remove any rust, dirt, or oil buildup. This step ensures the magnet will work effectively without being impeded by any debris. You can use paint thinner or a lubricant like WD-40 if the shaft is particularly oily.
Now, it's time to apply the magnet. Hold the screwdriver or screw bit in one hand and touch the magnet to the shaft, starting from the base and moving towards the tip. Slide the magnet from the handle of the screwdriver to the tip, rotating the screwdriver slightly between each turn. Repeat this motion about 10-15 times, using the same end of the magnet each time.
After magnetizing the screwdriver, test its strength by attempting to pick up a screw. If the attraction is strong enough, the magnetized screwdriver should be able to lift and hold the screw. If the attraction is weak, you may need to repeat the magnetizing process or use a stronger magnet.
If the screw is successfully attracted to the magnetized screwdriver, you can then use the screwdriver to remove the stuck screw from the electric screwdriver. The magnetic force will help hold the screw in place, allowing you to apply the necessary force to unscrew it.
Remember, once you have removed the stuck screw, you can demagnetize the screwdriver by running the magnet along the shaft in the opposite direction, from the tip to the handle. Additionally, dropping the screwdriver from a reasonable height onto a hard surface can also demagnetize it.

Applying super glue
When removing a stripped screw, increasing the friction between the screw and the driver is one of the simplest methods. This can be done by using a larger screwdriver or drill bit to increase the surface contact and friction between the bit and the head of the screw. However, this may only work for slightly damaged screws, and there is a risk of causing further damage to the screw head.
If the screw is severely stripped, other methods such as super glue, extractor kits, or a rotary tool can be used. To use super glue to remove a stripped screw from an electric screwdriver, follow these steps:
Prepare the screw: Before applying the super glue, ensure that the screw is slightly loosened. This can be done by using a screwdriver that is a size larger than the screw or trying different head sizes to see if they catch on any part of the stripped screw.
Apply super glue: Place a small drop of super glue onto the head of the screw. Use just enough glue to cover the stripped portion of the screw, avoiding any excess that may drip or run. Low to medium-strength super glue is recommended to avoid the risk of damaging the screw or the screwdriver.
Insert screwdriver: Gently insert the screwdriver or driver bit into the wet super glue. Ensure that the screwdriver is firmly lodged in the glue and centred on the screw head. Hold it tightly for about 10 seconds to allow the glue to set and create a strong bond.
Remove the screw: Once the glue has set, slowly attempt to unscrew it. Be cautious not to break the bond created by the super glue. If the screw does not come out easily, try increasing the downward pressure gradually to avoid damaging the screw or screwdriver.
Clean the screwdriver: After successfully removing the screw, remember to clean the remains of the glue from the tip of the screwdriver. This will ensure that the screwdriver is ready for future use without any glue residue interfering with its performance.
If the super glue method does not work, there are alternative approaches to removing a stripped screw. One option is to use a rotary tool to cut a small slit in the screw head, allowing for removal with a flathead screwdriver. Another method is to use an extractor kit or a special drill bit specifically designed for removing stripped screws. As a last resort, a drill can be used to drill out the screw, but this will require creating new threads.

Using a hammer
Step 1: Prepare the Screwdriver and Hammer
Place the screwdriver bit into the screw head. Ensure the screwdriver is firmly in position. Hold the screwdriver with one hand, keeping a firm grip on it.
Step 2: Tap with the Hammer
Using your other hand, hold the hammer. Gently tap the base of the screwdriver with the hammer. This impact will help lodge the screwdriver into the screw head, providing more grip.
Step 3: Attempt to Remove the Screw
Once the screwdriver is securely lodged, set down the hammer. Now, try to remove the screw by turning it counterclockwise. This method works especially well with soft metal screws.
Step 4: Alternative Hammer Technique
If the screw is still stuck, try a different approach. Place the screwdriver bit into the screw head, and this time, gently tap the screw head with the hammer a few times. This impact can help loosen the screw, especially if combined with a rust penetrant or lubricant.
Step 5: Using Heat and Oil
For stubborn screws, consider using some additional techniques in conjunction with the hammer method. Apply heat to the screw with a lighter or similar tool, and also apply some penetrating oil. These steps can help break down any rust or debris contributing to the screw being stuck.
Step 6: Clamp-Locking Pliers
If the screw still resists removal, try using clamp-locking pliers. Grip the screw head or shank with the pliers and twist and pull to loosen it. This technique is especially useful when the screw head is too smooth or flush to grip effectively with your fingers.
Remember to exercise caution when using tools, and always wear appropriate safety gear, including eye protection.

Using an impact driver
Firstly, ensure you have the right tool for the job. There are a variety of impact drivers available, from the powerful Koken Attack Driver to the more affordable Craftsman. The latter is a good choice if you're on a budget, as it's cheaper than the Lisle or Koken and comes with an easy warranty.
Next, you'll want to set up your impact driver. Most manual impact drivers have a three-eighths-inch or half-inch anvil to hold an adaptor. You can also add a socket to loosen a stuck hex cap screw. Put the impact driver in reverse, and consider adding a little valve lapping compound to the bit for added grip.
Now you're ready to start removing the screw. Place the impact driver on the screw and hit it once with a hammer. This twisting motion, combined with hammering, should be enough to get the screw loose without causing any damage. If the screw is particularly stubborn, try heating things up with a torch to break the rust bond.
Finally, maintain a good grip on your tool and press firmly downward as you work. This will help you avoid stripping the screw and make it easier to remove.
