Ah, the frustration of dealing with a broken screw stuck in an anchor! It’s a problem that can bring even the most seasoned DIY enthusiast or professional to their knees. But fear not, dear reader, for we’re about to embark on a journey to overcome this pesky predicament together.
Understanding the Problem
Before we dive into the solution, let’s take a step back and understand why removing a broken screw from an anchor can be such a challenge. Anchors are designed to provide a secure hold in walls, concrete, or other materials, and screws are meant to fit snugly into them. However, when a screw breaks, it can become lodged in the anchor, making it difficult to remove.
There are several reasons why a screw might break in an anchor, including:
- Over-tightening: Applying too much torque can cause the screw to snap, leaving it stuck in the anchor.
- Material weakness: Using a screw that’s not suitable for the anchor or the surface it’s being fastened to can lead to breakage.
- Corrosion: Exposure to moisture or harsh environmental conditions can cause the screw to weaken and break.
- Poor installation: If the screw is not installed correctly, it can lead to breakage over time.
Tools and Materials Needed
Before we begin, make sure you have the following tools and materials at your disposal:
- A broken screw extraction kit (available at most hardware stores or online)
- A drill with a screwdriver bit
- A drill bit set (including left-hand bits)
- Pliers or grips
- Safety glasses
- A screw extractor (optional)
Method 1: Using a Broken Screw Extraction Kit
A broken screw extraction kit is a specialized tool designed specifically for removing broken screws. These kits usually include a set of left-hand bits and an extractor.
Step-by-Step Instructions
- Begin by selecting the appropriate left-hand bit from the kit that matches the size of the broken screw.
- Insert the bit into your drill and set it to reverse.
- Place the bit onto the broken screw and apply gentle to moderate pressure.
- Slowly start drilling in reverse, allowing the bit to grip the screw.
- As you drill, the screw should begin to extract from the anchor.
- Continue drilling until the screw is removed completely.
Important Tip: Be patient and gentle when using the extraction kit, as excessive force can cause the screw to break further or damage the anchor.
Method 2: Using Pliers or Grips
If you don’t have access to a broken screw extraction kit, you can try using pliers or grips to remove the broken screw.
Step-by-Step Instructions
- Put on your safety glasses to protect yourself from flying debris.
- Use pliers or grips to carefully grasp the head of the broken screw.
- Apply gentle to moderate pressure, trying to rock the screw back and forth while pulling it out.
- If the screw doesn’t budge, try using a bit more force, but be cautious not to apply too much pressure, which can cause the screw to break further.
- If the screw starts to move, continue to rock it back and forth while pulling until it’s removed completely.
Important Tip: Be careful not to slip and damage the surrounding material or anchor.
Method 3: Drilling Out the Screw
As a last resort, you can try drilling out the screw. This method should only be used if the above methods fail, as it can damage the anchor or surrounding material.
Step-by-Step Instructions
- Select a drill bit that’s slightly larger than the screw.
- Place the bit onto the screw and start drilling slowly and carefully.
- Apply gentle to moderate pressure, gradually increasing the pressure as needed.
- Continue drilling until the screw is completely removed.
- Be prepared to clean up any debris or shavings from the drilling process.
Important Tip: Use caution when drilling out the screw, as it can cause the anchor or surrounding material to weaken or crack.
Avoiding Future Breakages
Now that we’ve removed the broken screw, let’s take a look at some tips to avoid future breakages:
- Use the right screw for the job: Ensure you’re using screws that are suitable for the anchor and surface material.
- Follow installation instructions: Read and follow the manufacturer’s installation instructions to avoid over-tightening or poor installation.
- Inspect your screws: Regularly inspect your screws for signs of wear, corrosion, or damage.
- Store screws properly: Store screws in a dry, clean environment to prevent corrosion.

What is the best way to remove a broken screw from an anchor?
The best way to remove a broken screw from an anchor is to use a combination of techniques and tools. First, try to extract the screw by using a screw extractor or a drill bit that is slightly larger than the screw. If this doesn’t work, you may need to use a more aggressive approach, such as drilling out the screw or using a screw removal kit.
It’s important to be patient and gentle when attempting to remove a broken screw, as excessive force or twisting can damage the anchor or surrounding material. Additionally, make sure to use the appropriate tools and techniques for the type of screw and anchor you are working with.
What are some common reasons why screws break in anchors?
Screws can break in anchors for a variety of reasons, including over-tightening, rust or corrosion, or using the wrong type of screw for the anchor. In some cases, the screw may have been stripped or damaged during installation, making it more prone to breaking. Additionally, environmental factors such as extreme temperatures or exposure to moisture can also contribute to screw failure.
To avoid breaking screws in the future, make sure to follow proper installation techniques and use high-quality screws and anchors that are suitable for the application. Regular maintenance and inspection of the anchors and screws can also help identify potential issues before they become major problems.
Can I use a drill to remove a broken screw?
In some cases, a drill can be used to remove a broken screw, but it’s not always the best approach. If the screw is stuck or broken off flush with the anchor, drilling may be the only option. However, drilling can be risky, as it can damage the anchor or surrounding material.
Before attempting to drill out a broken screw, make sure to use a drill bit that is slightly larger than the screw and take your time to avoid damaging the surrounding material. Additionally, use caution when drilling to avoid creating a new hole or compromising the structural integrity of the anchor.
What is a screw extractor, and how does it work?
A screw extractor is a tool specifically designed to remove broken or damaged screws from anchors or other materials. It works by attaching to the screw and then applying a controlled amount of torque to slowly extract the screw from the anchor.
The extractor uses a series of left-hand threads to grip the screw, allowing you to carefully remove it without damaging the surrounding material. Screw extractors come in different sizes and styles, so make sure to choose the right one for your specific application.
Can I use a hair dryer or heat gun to remove a broken screw?
In some cases, applying heat to the screw and anchor can help loosen the screw and make it easier to remove. This method can be especially useful if the screw is stuck due to rust or corrosion.
However, use caution when applying heat, as excessive heat can damage the anchor or surrounding material. Start with low heat and gradually increase the temperature as needed. Be sure to wear protective gloves and safety glasses when attempting to remove a broken screw using heat.
How can I prevent screws from breaking in the future?
To prevent screws from breaking in the future, make sure to follow proper installation techniques, such as using the correct type and size of screw for the anchor. Additionally, avoid over-tightening the screw, as this can cause it to strip or break.
Regular maintenance and inspection of the anchors and screws can also help identify potential issues before they become major problems. Consider using screws with a protective coating or surface finish to resist corrosion and rust.
What if I’m not comfortable removing a broken screw myself?
If you’re not comfortable removing a broken screw yourself, it’s always best to consult a professional. A handyman or contractor with experience in anchor installation and screw removal can safely and efficiently remove the broken screw and replace it with a new one.
Don’t risk damaging the anchor or surrounding material by attempting to remove the screw yourself. Instead, seek the help of a professional who has the necessary expertise and tools to get the job done correctly.
