There’s nothing more frustrating than stripping or breaking a screw head, especially when you’re in the middle of a critical project or repair. It’s like hitting a roadblock, and your progress comes to a screeching halt. But fear not, dear DIY enthusiast or handyman, for this article is here to guide you through the process of unscrewing a broken screw head and getting your project back on track.
Why Do Screw Heads Break?
Before we dive into the solution, it’s essential to understand why screw heads break in the first place. There are several reasons why this might happen:
1. Over-tightening
One of the most common reasons for a broken screw head is over-tightening. When you apply too much torque to a screw, the head can strip or break, making it impossible to remove. This is especially true for smaller screws or those made of softer materials.
2. Using The Wrong Screwdriver
Using a screwdriver that’s not designed for the type of screw you’re working with can lead to stripped or broken screw heads. For example, using a flathead screwdriver on a Phillips head screw can cause the head to break or strip.
3. Rust Or Corrosion
Rust or corrosion can weaken the screw head, making it prone to breaking or stripping. This is especially common in outdoor or high-moisture environments.
4. Poor Quality Screws
Unfortunately, some screws are just made with inferior materials or manufacturing processes, which can lead to a higher likelihood of broken screw heads.
Unscrewing A Broken Screw Head: Methods And Techniques
Now that we’ve covered why screw heads break, let’s explore the various methods and techniques for unscrewing a broken screw head.
1. Using A Screw Extractor
A screw extractor is a handy tool designed specifically for removing broken or stripped screws. It works by drilling a small hole in the center of the screw and then using a series of left-handed bits to remove the screw. Screw extractors are available at most hardware stores or online.
Tip:** When using a screw extractor, make sure to apply gentle pressure to avoid damaging the surrounding material.
2. Applying Heat
Sometimes, a broken screw head can be removed by applying heat to the area. This can help expand the metal, making it easier to remove. You can use a hair dryer or heat gun to apply heat to the screw head. Be careful not to apply too much heat, as this can damage the surrounding material.
3. Using A Broken Screw Head Remover
A broken screw head remover is a specialized tool designed to remove broken screw heads without damaging the surrounding material. It works by drilling a small hole in the center of the screw and then using a series of pins to remove the screw.
Tip:** When using a broken screw head remover, make sure to follow the manufacturer’s instructions carefully to avoid damaging the surrounding material.
4. Drilling Out The Screw
If all else fails, you may need to drill out the screw entirely. This should be considered a last resort, as it can damage the surrounding material. Use a drill bit that’s slightly larger than the screw and carefully drill out the screw, taking care not to damage the surrounding material.
Additional Tips And Tricks
In addition to the methods outlined above, here are some additional tips and tricks to help you unscrew a broken screw head:
1. Apply Penetrating Oil
Before attempting to remove a broken screw head, apply penetrating oil to the area. This can help loosen the screw and make it easier to remove.
2. Use A Socket Or Wrench
If the broken screw head is large enough, try using a socket or wrench to remove it. This can provide extra leverage and make it easier to remove the screw.
3. Clean The Area
Make sure the area around the broken screw head is clean and free of debris. This can help the removal process and prevent further damage to the surrounding material.
Conclusion
Unscrewing a broken screw head can be a frustrating and challenging task, but with the right tools and techniques, it’s entirely possible. By understanding why screw heads break and using the methods outlined in this article, you can remove broken screw heads with ease and get your project back on track. Remember to always take your time, be patient, and use caution when working with broken screw heads to avoid damaging the surrounding material. With practice and experience, you’ll become a pro at unscrewing broken screw heads in no time!
What Is The Most Common Reason For A Screw Head To Break?
The most common reason for a screw head to break is applying too much torque or force when trying to remove it. When you use a screwdriver that is too large or too small for the screw, or when you apply too much pressure, it can cause the screw head to strip or break. This is especially true for screws made of softer materials like aluminum or brass.
Additionally, using the wrong type of screwdriver, such as a flathead screwdriver on a hex head screw, can also cause the screw head to break. It’s essential to use the correct type and size of screwdriver for the screw you’re working with to avoid damaging the screw head.
How Can I Prevent Screw Heads From Breaking In The Future?
To prevent screw heads from breaking in the future, it’s crucial to use the correct type and size of screwdriver for the screw you’re working with. Make sure the screwdriver is securely seated in the screw head and apply gentle, consistent pressure. Avoid using too much force or applying pressure at an angle, as this can cause the screw head to strip or break.
It’s also a good idea to clean the screw head and surrounding area before attempting to remove the screw. This will help ensure a good grip on the screw and reduce the likelihood of the screw head breaking. Additionally, consider using screws made of high-quality materials that are less prone to breaking.
What Tools Do I Need To Unscrew A Broken Screw Head?
The tools you need to unscrew a broken screw head will depend on the type of screw and the severity of the break. In some cases, you may be able to use a screw extractor, which is a specialized tool designed specifically for removing broken screws. In other cases, you may need to use a drill and a specialized bit, such as a left-handed drill bit, to remove the screw.
It’s also a good idea to have a variety of screwdrivers on hand, including flathead and hex (or Allen) wrench screwdrivers. You may also need pliers, wire cutters, or other gripping tools to help you remove the broken screw head.
Can I Use A Drill To Remove A Broken Screw Head?
Yes, in some cases, you can use a drill to remove a broken screw head. A left-handed drill bit can be used to drill out the broken screw, allowing you to remove it. However, this method should be used with caution, as it can cause damage to the surrounding material.
It’s essential to use the correct type and size of drill bit for the screw and to apply gentle, consistent pressure. You should also use a steady, controlled motion to avoid slipping and causing further damage. If possible, it’s best to consult a professional or someone with experience in this area.
What If The Broken Screw Head Is In A Hard-to-reach Area?
If the broken screw head is in a hard-to-reach area, you may need to use specialized tools or techniques to remove it. For example, you may need to use a flexible shaft or extension bit to reach the screw head. Alternatively, you may need to disassemble surrounding components to access the broken screw head.
In some cases, you may need to consult a professional or someone with experience in this area to remove the broken screw head. They will have the necessary tools and expertise to safely and effectively remove the screw.
Can I Use A Hair Dryer Or Heat Gun To Remove A Broken Screw Head?
Yes, in some cases, you can use a hair dryer or heat gun to remove a broken screw head. Applying heat to the screw head can cause it to expand, making it easier to remove. This method is especially effective for screws made of materials that are sensitive to heat, such as aluminum or brass.
However, this method should be used with caution, as excessive heat can cause damage to the surrounding material. It’s essential to apply gentle, consistent heat and to avoid overheating the screw or surrounding area.
Are Screw Extractors Worth The Investment?
Yes, screw extractors are worth the investment, especially if you work with screws frequently. Screw extractors are specialized tools that are designed to remove broken or damaged screws, making them an essential tool for anyone who regularly works with screws.
While they may seem like a luxury item, screw extractors can save you time and frustration in the long run. They can also help you avoid causing further damage to the surrounding material, which can save you money and hassle in the long run.
