Screw extractors are a lifesaver when it comes to removing stuck or damaged screws. They can be a DIYer’s best friend, but what happens when they don’t work as expected? You’re left with a stubborn screw, a damaged surface, and a whole lot of frustration. In this article, we’ll explore what to do when a screw extractor doesn’t work, and how to prevent these situations from arising in the first place.
Why Screw Extractors Fail
Before we dive into the solutions, it’s essential to understand why screw extractors fail. There are several reasons why a screw extractor might not work as expected:
Incorrect Screw Extractor Type
One of the most common reasons screw extractors fail is because the wrong type is used for the job. There are different types of screw extractors, each designed for specific screw types and materials. Using the wrong extractor can damage the screw, the surrounding material, or both.
Insufficient Screw Engagement
If the screw extractor doesn’t engage with the screw properly, it can lead to failure. This can happen if the screw is too small, too large, or if the extractor’s teeth are worn out.
Inadequate Drilling
Drilling a pilot hole that’s too small or too large can affect the extractor’s performance. If the hole is too small, the extractor might not fit properly, and if it’s too large, the extractor might not grip the screw correctly.
Screw Material Hardness
Screws made from hardened materials like stainless steel or titanium can be challenging to remove, even with a screw extractor. If the extractor is not designed for these types of screws, it can lead to failure.
When to Know It’s Time to Move On
Sometimes, despite your best efforts, the screw extractor just won’t work. Here are some signs it’s time to move on:
The Screw is Still Intact
If the screw extractor has managed to damage the screw but not remove it, it’s time to consider alternative methods. Continuing to use the extractor can lead to further damage and potentially make the situation worse.
The Surrounding Material is Damaged
If the screw extractor has damaged the surrounding material, such as wood or metal, it’s essential to stop immediately. Continuing to use the extractor can lead to further damage and compromise the structural integrity of the material.
You’ve Tried Multiple Extractors
If you’ve tried multiple screw extractors and none of them have worked, it’s time to explore other options. This is especially true if you’ve tried different types of extractors, such as manual and drill-powered models.
Alternative Methods for Removing Stuck Screws
When a screw extractor fails, it’s time to think outside the box. Here are some alternative methods for removing stuck screws:
Heat and Penetrating Oil
Applying heat to the screw and surrounding area can help loosen it. Use a hair dryer or heat gun to warm up the area, then apply penetrating oil like WD-40 or Liquid Wrench. Let the oil sit for a while before trying to remove the screw.
Drilling Out the Screw
In some cases, it’s possible to drill out the screw entirely. This method works best for screws in soft materials like wood or plastic. Use a drill bit that’s slightly larger than the screw’s diameter and carefully drill out the screw. Be cautious not to damage the surrounding material.
Using a Screw Cutting Tool
A screw cutting tool, also known as a screw saw, is a specialized tool designed to cut through screws. This method is useful for screws that are too large or too stuck to remove with an extractor.
Preventing Screw Extractor Failure
While it’s essential to know what to do when a screw extractor fails, it’s even more important to prevent these situations from arising in the first place. Here are some tips to help you prevent screw extractor failure:
Choose the Right Screw Extractor
Take the time to select the right screw extractor for the job. Consider the type of screw, material, and size to ensure you’re using the correct extractor.
Drill Pilot Holes Correctly
Drill pilot holes that are the correct size for the extractor. Use a drill bit that’s slightly smaller than the extractor’s diameter to ensure a proper fit.
Use the Correct Drilling Technique
Use a slow, steady drilling technique when creating the pilot hole. Apply gentle to moderate pressure, and avoid applying too much pressure, which can damage the surrounding material.
Maintain Your Screw Extractors
Regularly clean and maintain your screw extractors to ensure they’re in good working condition. This includes cleaning out debris, lubricating the extractor’s teeth, and storing them properly.
Conclusion
Screw extractors are a valuable tool in any DIYer’s arsenal, but they’re not infallible. When a screw extractor fails, it’s essential to know what to do next. By understanding why screw extractors fail and knowing alternative methods for removing stuck screws, you can overcome even the most challenging projects. Remember to prevent screw extractor failure by choosing the right extractor, drilling pilot holes correctly, using the correct drilling technique, and maintaining your extractors. With these tips, you’ll be well on your way to becoming a screw-extracting master.
What happens when a screw extractor breaks off in the screw?
When a screw extractor breaks off in the screw, it can be a frustrating and difficult situation to resolve. In this case, the remaining extractor piece is now lodged in the screw, making it even harder to remove the screw. This can lead to further damage to the surrounding material or even cause the screw to become stripped, making it impossible to remove.
It’s essential to remain calm and not attempt to force the screw out, as this can exacerbate the problem. Instead, assess the situation and consider alternative removal methods, such as using a drill or milling machine to carefully remove the screw. If you’re not confident in your ability to remove the screw, it may be best to seek the assistance of a professional.
Can I use pliers or locking pliers to remove a screw with a broken extractor?
While it may be tempting to use pliers or locking pliers to grip the broken extractor and try to remove the screw, this approach is not recommended.
