Stripped screws are the bane of any DIY enthusiast, woodworker, or even just someone trying to assemble furniture. That frustrating moment when your screwdriver spins uselessly in the screw head can quickly turn a simple project into a major headache. You’ve likely tried applying more pressure, using a larger screwdriver, or even resorting to cuss words. But have you ever considered super glue?
The internet is rife with suggestions on how to remove stripped screws, and the super glue trick is a popular one. But does it actually work? And if so, what are the caveats? Let’s explore this sticky situation in detail.
Understanding the Problem: What is a Stripped Screw?
Before we delve into the super glue solution, it’s crucial to understand what a stripped screw actually is. A stripped screw, in essence, is a screw where the head’s internal threading has been damaged. This damage prevents the screwdriver from properly gripping, making it impossible to turn and either tighten or remove the screw.
This stripping can occur for various reasons. Overtightening is a common culprit. Applying too much force when tightening a screw can shear off the delicate metal ridges inside the screw head, especially with softer metals like brass or aluminum.
Using the wrong size or type of screwdriver is another frequent cause. A screwdriver that’s too small will wobble and wear away at the screw head. Using a Phillips head screwdriver on a Pozidriv screw (or vice versa) will also lead to stripping.
The quality of the screw itself plays a role. Cheap screws are often made with inferior metals that are more prone to stripping. Repeated use can also wear down the screw head over time, eventually leading to stripping.
The Super Glue Solution: How It’s Supposed to Work
The basic premise of using super glue to remove a stripped screw is to create a stronger bond between the screwdriver and the damaged screw head. By filling the stripped areas with super glue, you essentially create a new, albeit temporary, set of “threads” that the screwdriver can grip.
The idea is that once the glue hardens, it will provide enough friction and purchase to allow you to turn the screw. In theory, this sounds like a simple and effective solution. But the devil, as always, is in the details.
The Process, Step-by-Step
If you’re going to attempt the super glue method, here’s a general outline of the steps involved:
- Gather your supplies: You’ll need super glue (cyanoacrylate adhesive), a screwdriver that fits the screw as snugly as possible (even if it’s slightly damaged), and potentially some degreaser or cleaner.
- Clean the screw head: This is crucial. Use a degreaser or cleaner to remove any oil, grease, or debris from the screw head. A clean surface will allow the super glue to bond more effectively.
- Apply the super glue: Carefully apply a small amount of super glue to the screw head. You want to fill the stripped areas without overflowing the glue onto the surrounding surface.
- Insert the screwdriver: Immediately insert the screwdriver into the screw head and apply gentle pressure. Hold it firmly in place.
- Allow the glue to cure: This is the most important step. You need to allow the super glue to fully cure and harden. This usually takes at least several minutes, but it’s best to err on the side of caution and wait longer. Refer to the super glue’s instructions for the recommended curing time.
- Attempt to remove the screw: Once the glue has fully cured, carefully try to turn the screwdriver. Apply steady, even pressure. Avoid jerking or forcing the screw, as this could break the glue bond.
What Kind of Super Glue Works Best?
Not all super glues are created equal. For this particular task, you’ll want to choose a super glue that is known for its strong bonding strength and fast curing time. Cyanoacrylate adhesives are the standard super glue type and are readily available. Gel-based super glues can be useful as they tend to be less runny and easier to control, preventing them from dripping onto the surrounding surface.
Consider the viscosity of the glue. A thicker glue might be better for filling larger stripped areas, while a thinner glue might be more effective for penetrating smaller crevices. Read product reviews and compare different brands to find a super glue that’s well-suited for this type of application.
The Reality Check: Why It Might Not Work
While the super glue trick sounds promising, it’s important to acknowledge its limitations. There are several reasons why this method might not work, and in some cases, it could even make the problem worse.
One major issue is the strength of the bond. While super glue is strong, it’s not a miracle worker. If the screw is severely stripped, the glue bond might not be strong enough to withstand the torque required to remove it. The glue could simply break, leaving you with an even stickier situation.
Another problem is the potential for the glue to bond to the surrounding material. If the glue overflows from the screw head, it could adhere to the surrounding wood, plastic, or metal. This can make it even more difficult to remove the screw, and you could end up damaging the surrounding surface.
Furthermore, the type of screw and the material it’s embedded in can affect the success of the super glue method. Screws that are deeply embedded in hard materials might be more difficult to remove, even with the added grip of the super glue. The method is more likely to be successful with screws that are only lightly stripped and embedded in softer materials.
Potential Downsides and Risks
Before you reach for the super glue, consider the potential downsides and risks associated with this method. As mentioned earlier, the glue could bond to the surrounding material, causing damage. Removing the screw could then become much more challenging, potentially requiring more drastic measures like drilling.
Super glue can also be difficult to clean up. If you get it on your skin, it can be tricky to remove. If it drips onto a finished surface, it can leave a permanent stain. Always wear gloves and protect the surrounding area when working with super glue.
There is also the risk of the glue failing and leaving residue within the screw head, complicating future attempts to remove it with other methods. It might require cleaning the screw head thoroughly before attempting other solutions.
Alternative Methods for Removing Stripped Screws
Fortunately, the super glue trick isn’t the only option for removing stripped screws. There are several other methods you can try, some of which are more reliable and less risky.
- Rubber Band Trick: Place a wide rubber band over the screw head, then insert your screwdriver. The rubber band can fill the stripped gaps and provide extra grip. This is often the first and easiest thing to try.
- Screw Extractors: These are specialized tools designed to bite into the stripped screw head and provide a new gripping surface. They come in various sizes and types, and can be very effective for removing stubborn screws.
- Specialty Screwdrivers: Impact screwdrivers are designed to deliver a sudden burst of rotational force, which can help to loosen a stuck screw.
- Pliers or Vise-Grips: If the screw head is exposed, you might be able to grip it with pliers or vise-grips and turn it out.
- Drilling: As a last resort, you can drill out the screw head. This will destroy the screw, but it will allow you to remove the material it was holding together. You can then use pliers to remove the remaining screw shank, or use screw extractors.
- Using a Dremel: Use a Dremel tool with a cutting disc to create a new slot in the screw head. Then, use a flathead screwdriver to remove the screw.
- Heat: Applying heat to the screw head with a soldering iron can help to loosen any corrosion or adhesive that might be holding it in place.
These alternative methods are generally safer and more reliable than the super glue trick, although they might require more specialized tools or skills.
When to Call in the Professionals
Sometimes, despite your best efforts, a stripped screw is simply too stubborn to remove. In these cases, it’s best to call in a professional. A carpenter, handyman, or mechanic will have the experience and specialized tools to remove the screw without damaging the surrounding material. This is especially important if the screw is located in a critical area or if you’re worried about causing further damage.
Final Verdict: Is Super Glue a Viable Solution?
So, can super glue really rescue a stripped screw? The answer is a qualified maybe. In some cases, it can be a quick and easy fix. However, it’s not a guaranteed solution, and it comes with certain risks.
The super glue trick is most likely to work on screws that are only lightly stripped and embedded in softer materials. It’s less likely to be successful on screws that are severely stripped or located in hard-to-reach areas.
Before resorting to super glue, try other methods like the rubber band trick or using a larger screwdriver. If those methods fail, carefully consider the potential risks and downsides before attempting the super glue solution. And if you’re unsure, it’s always best to consult with a professional.
Ultimately, removing stripped screws is a common challenge, and having a variety of techniques at your disposal is essential. While super glue might be a useful trick to have in your toolbox, it’s not a silver bullet. Choose the method that’s best suited for the specific situation and always prioritize safety and the prevention of further damage.
What types of screws are best suited for the super glue trick?
The super glue trick tends to work best on screws that have rounded-out heads or slightly stripped threads, especially those in softer materials like wood or plastic. The adhesive provides enough grip to allow a screwdriver to catch and turn the screw. However, it is significantly less effective on severely stripped screws where the head is completely mangled or the threads are entirely gone, as there isn’t a solid surface for the glue to bind to and transfer force.
Consider the material surrounding the screw as well. This method works better when the material is porous enough to allow the glue to grip securely. Avoid using this method on screws that are deeply embedded or in sensitive electronics where glue residue could cause damage. A more specialized screw extractor might be necessary in these tougher scenarios.
How much super glue should I use for this technique?
The key to success is using a conservative amount of super glue. Just a single small drop or two is generally sufficient to create a temporary bond. Overusing the glue can actually hinder the process, making it more likely to seep into the threads and permanently bond the screw in place, making future removal even more difficult.
Apply the glue directly to the screw head where the screwdriver will make contact. Allow it to dry completely before attempting to turn the screw. This drying time is crucial for the glue to form a strong enough, yet temporary, bond between the screw and the screwdriver. The exact drying time will vary based on the type of super glue used, so always refer to the manufacturer’s instructions.
What type of super glue works best for rescuing stripped screws?
Cyanoacrylate-based super glue, the most common type, is generally sufficient for this task. Look for a glue with a medium viscosity, as it will flow easily to fill gaps but won’t run excessively. Gel-based super glues can also work well, especially if you need to fill a larger gap in the screw head.
Avoid using super glues that are specifically designed for flexible materials, as they may not provide enough rigidity to grip the screw effectively. Also, avoid super glues that are designed for gap-filling unless the screw head is heavily damaged. Experiment on a similar screw and material beforehand if you’re unsure about a particular glue’s effectiveness.
What type of material should I use between the screwdriver and screw for the glue to bond?
Often, a piece of steel wool or a rubber band can provide a better surface for the glue to grip and create a stronger bond. The texture of these materials adds extra friction, allowing the screwdriver to get a better hold on the stripped screw head. This prevents the screwdriver from slipping and further damaging the screw.
Cut a small piece of either steel wool or rubber band. Apply a small amount of super glue to the material and then press it firmly into the stripped screw head. Allow the glue to dry completely before attempting to turn the screw. Make sure the material completely fills the gap between the screwdriver and the screw for optimal results.
Are there any risks associated with using super glue on stripped screws?
One of the biggest risks is permanently bonding the screw in place. If too much glue is used or it seeps into the threads, the screw can become impossible to remove without damaging the surrounding material. Additionally, some super glues can damage certain plastics or finishes, so always test a small, inconspicuous area first.
Another potential risk involves personal safety. Super glue can bond skin very quickly, so exercise caution when applying it. Wear gloves to protect your hands and avoid getting the glue in your eyes. Always work in a well-ventilated area to avoid inhaling the fumes.
When is it best to abandon the super glue method and try another approach?
If the screw is severely stripped with virtually no head remaining or if the threads are completely destroyed, the super glue method is unlikely to work. Similarly, if you’ve tried this method once or twice without success, it’s probably best to move on to a different technique to avoid further complicating the situation.
Consider alternative methods such as using a screw extractor, a specialized tool designed to grip and remove stripped screws. Applying heat to loosen the screw or cutting a new slot in the head with a rotary tool are also viable options. Sometimes, simply trying a different screwdriver with a better fit can also do the trick.
How can I prevent screws from stripping in the first place?
Using the correct size and type of screwdriver is crucial. A screwdriver that is too small or too large can easily slip and strip the screw head. Applying steady, even pressure while turning the screw can also help prevent stripping. Avoid forcing the screw if it’s meeting resistance.
Consider lubricating the screw threads with a small amount of oil or wax, especially when working with hard materials. Also, be mindful of the angle at which you’re driving the screw; angling the screwdriver can put uneven pressure on the screw head and increase the risk of stripping. Using power tools with adjustable torque settings can also help prevent over-tightening.
