What You'll Learn
Using a Rubber Band
When faced with a stripped plastic screw, one surprisingly effective and simple method to try is using a rubber band. This technique works by increasing the friction between the screw head and the screwdriver, allowing you to gain the necessary grip to turn the screw out. Start by placing a wide rubber band flat over the stripped screw head, ensuring it covers the entire surface. The rubber band should be thick enough to fill in the gaps created by the stripped grooves, but not so thick that it prevents the screwdriver from fitting properly.
Next, press the screwdriver firmly onto the screw head, through the rubber band. The rubber band will compress slightly, conforming to the shape of the screwdriver tip and the damaged screw head. This compression creates a tighter fit, enhancing the grip. Apply steady downward pressure to ensure the screwdriver is seated as deeply as possible into the screw head. It’s crucial to use a screwdriver that matches the original screw type as closely as possible, even if the screw is stripped, to avoid further damage.
Once the screwdriver is in place, begin turning it counterclockwise with steady, firm pressure. The rubber band acts as a friction-enhancing layer, helping the screwdriver catch on the screw head. If the screw doesn’t turn immediately, apply slightly more force, but be careful not to overdo it, as excessive force can break the screw or damage the surrounding material. Patience is key, as the rubber band method may require a few attempts to succeed.
If the screw still resists, try using a fresh section of the rubber band or a new rubber band altogether, as the material can wear out quickly under pressure. Additionally, ensure the rubber band is not too loose or too tight—it should be snug enough to provide grip but not so tight that it hinders the screwdriver’s movement. This method is particularly useful for smaller screws where precision is essential, and it’s a great alternative to more invasive techniques like drilling or extracting.
Finally, once the screw begins to turn, maintain steady pressure and continue rotating until it is fully removed. After removal, inspect the screw hole and surrounding area for any damage caused by the stripped screw. If the hole is damaged, it may need to be repaired before inserting a new screw. Using a rubber band is a cost-effective, tool-friendly solution that often works when other methods fail, making it a valuable trick to have in your DIY toolkit.

Applying Penetrating Oil
Once you have your penetrating oil, apply it generously to the stripped screw. Hold the nozzle close to the screw head and spray a liberal amount, ensuring the oil covers the entire screw head and threads. If the screw is deeply embedded, use the straw attachment that often comes with the oil can to direct the spray into the crevices. Allow the oil to sit for at least 10 to 15 minutes, giving it ample time to work its way into the threads and loosen the bond between the screw and the material. For particularly stubborn screws, you may need to reapply the oil and let it sit for an additional 10 to 15 minutes.
While the oil is penetrating, avoid disturbing the screw to ensure it remains saturated. After the waiting period, attempt to turn the screw gently using a screwdriver or a screw extraction tool. If the screw still doesn’t budge, apply more oil and let it sit for another 15 to 30 minutes. Penetrating oil works by reducing friction and breaking down rust or grime, so patience is key to its effectiveness. Repeat the process as needed until the screw begins to turn.
When applying penetrating oil, be mindful of the surrounding materials, especially if they are sensitive to chemicals. Cover or protect nearby surfaces if necessary. Additionally, work in a well-ventilated area, as the fumes from penetrating oils can be strong. If the screw is in a hard-to-reach spot, consider using a brush or a small applicator to ensure the oil reaches all areas of the screw.
Finally, once the screw starts to turn, apply gentle and steady pressure to avoid further stripping or breaking the screw. The penetrating oil will continue to assist in the removal process as you work the screw out. If the screw still resists, reapply the oil and consider using a screw extractor or other methods in conjunction with the oil for added effectiveness. With patience and proper application, penetrating oil can significantly increase your chances of successfully removing a stripped plastic screw.

Drilling Out the Screw
When drilling out a stripped plastic screw, the first step is to select the appropriate drill bit. Choose a bit that is slightly smaller than the diameter of the screw head. This ensures that you create a clean hole without damaging the surrounding material. A high-speed steel (HSS) drill bit is typically suitable for this task, as it can handle the hardness of most plastics. Secure the item containing the screw firmly in place to prevent it from moving during the drilling process, which could lead to mistakes or damage.
Next, mark the center of the screw head with a center punch to guide the drill bit. This step is crucial because it prevents the bit from wandering, which can cause uneven drilling or damage to the surrounding area. If you don’t have a center punch, a sharp object like an awl or a nail can be used as an alternative. Gently tap the punch with a hammer to create a small indentation directly in the center of the screw head.
With the center marked, begin drilling slowly and steadily. Apply light pressure and let the drill bit do the work. Drilling too aggressively can cause the plastic to melt or crack, making the removal process more difficult. Use a drill with variable speed control and start at a low speed to maintain precision. As you drill, periodically stop to clear any plastic debris from the hole to prevent clogging the bit and ensure a clean cut.
Once you’ve drilled through the screw head and into the shaft, stop drilling before you reach the bottom of the screw. The goal is to remove the head while leaving the shaft intact, as this often allows the remaining part of the screw to be easily extracted. If the screw is countersunk, be cautious not to drill too deeply into the material beneath it. After drilling, use a flathead screwdriver or a pair of pliers to carefully remove the remaining screw shaft.
Finally, inspect the hole to ensure it’s clean and free of any burrs or rough edges. If necessary, use a deburring tool or fine-grit sandpaper to smooth the area. This step is especially important if you plan to replace the screw or reinstall a new one, as a clean hole ensures a secure fit. Drilling out a stripped plastic screw requires patience and precision, but with the right tools and technique, it can be accomplished effectively.

Using a Screw Extractor
First, select the appropriate size screw extractor for the screw you’re dealing with. Screw extractors come in various sizes, so ensure the one you choose matches the diameter of the stripped screw. If the extractor is too large, it may damage the surrounding material, and if it’s too small, it won’t grip the screw effectively. Once you’ve chosen the right size, attach the extractor to a drill or a manual screwdriver. Ensure the extractor is securely fastened to prevent slipping during the removal process.
Next, align the screw extractor directly over the center of the stripped screw. This step is crucial for success, as misalignment can cause the extractor to bind or break. Apply gentle downward pressure while turning the extractor counterclockwise. The extractor’s spiral flutes will begin to bite into the screw, creating a thread pattern that allows it to grip the damaged screw. Be patient and avoid applying excessive force, as plastic is more prone to breaking than metal.
As you turn the extractor, you should feel it gradually gripping the screw. Continue turning counterclockwise until the extractor has firmly engaged with the screw. Once the extractor is securely embedded, apply steady, controlled force to unscrew the damaged screw. If the screw resists, you can use a drill on low speed to assist in turning the extractor. However, be cautious not to apply too much torque, as this can cause the extractor to break or further damage the surrounding material.
Finally, after the stripped plastic screw is removed, inspect the hole and surrounding area for any damage. If the extractor leaves behind small plastic shavings, clean them out carefully to ensure the hole is ready for a replacement screw. Using a screw extractor requires precision and patience, but it’s a reliable method for tackling stubborn stripped plastic screws when other techniques fail. Always prioritize safety and take your time to avoid complications.

Heating the Screw Head
Once the screw head is heated, quickly place the screwdriver into the stripped recess and apply firm, steady pressure while turning counterclockwise. The softened plastic will allow the screwdriver to grip the screw more effectively. If the screw still doesn’t budge, reapply heat for another 5-10 seconds and try again. It’s important to work swiftly, as the plastic will begin to harden again once it cools. This method is particularly useful for screws in delicate materials, as it minimizes the risk of cracking or breaking the surrounding plastic.
For screws in heat-sensitive materials, use a low-heat setting or a hairdryer instead of a heat gun or soldering iron. If you’re using a soldering iron, touch the tip gently to the screw head for a few seconds, then immediately attempt to remove the screw. Always wear protective gloves to avoid burns and ensure proper ventilation when working with heat tools. This technique is effective because plastic expands when heated, which can help break the bond between the screw and the material it’s fastened to.
If the screw remains stubborn, consider combining heating with another method, such as using a rubber band for added friction. Place a wide rubber band between the screwdriver and the screw head before applying heat and turning. The rubber band can help fill the gaps in the stripped recess, providing additional grip. However, ensure the rubber band doesn’t melt or catch fire from the heat source. This combined approach can often provide the extra leverage needed to remove the screw.
Finally, after successfully removing the screw, allow the area to cool completely before handling or reassembling. Inspect the screw hole for any damage caused by the heating process, and clean out any melted plastic residue if necessary. Heating the screw head is a reliable and non-destructive method when done carefully, making it a go-to solution for stripped plastic screws in various applications, from electronics to household items. Always prioritize safety and precision to achieve the best results.
