How To Fix A Broken Anchor Screw

A broken anchor screw can be a tricky problem to fix, and there are several methods to remedy the situation. One common solution is to use a pair of pliers to grip the screw and slowly turn it counterclockwise, requiring patience and persistence to remove it successfully. If the screw cannot be gripped with pliers, creating a slit at the top with a Dremel tool and then using a slotted screwdriver to unscrew it is another option. For screws without a head, using a drill with a larger version of a tapered extractor can be effective. In some cases, it may be necessary to cut the screw with a hacksaw blade and then use a straight screwdriver to remove it. When dealing with concrete anchors, drilling them out and filling the holes with hydraulic cement is recommended.

Removing a broken screw from a wall anchor

Step 1: Assess the Situation

Before you begin, it's important to understand the extent of the problem. Take a close look at the broken screw and identify the type of wall anchor involved. This will help you choose the most appropriate removal method.

Step 2: Gather Your Tools

Having the right tools is essential for successful screw removal. Here are some common tools that can be used for this task:

• Needle-nose pliers: Useful for gripping and turning the screw or anchor.
• Hammer and nail punch: This combination can be used to punch the screw into the wall.
• Drill: A drill can be used with various bits and attachments to extract the screw.
• Vice grips: These can provide a stronger grip than pliers and help turn the screw or anchor.
• Hacksaw blade: Used to cut a straight groove in the screw, creating an area for a screwdriver to grip.

Step 3: Attempt Initial Removal Methods

Start with the simplest methods first. If the screw head is still partially intact, try using pliers to grip and turn it counterclockwise. If pliers don't work, you can try a hammer and nail punch to drive the screw further into the wall. This may not remove the screw entirely, but it can push it out of the way.

Step 4: Employ More Advanced Techniques

If the initial methods don't work, it's time to try more advanced techniques. Here are some options:

• Use a drill: You can use a drill with a suitable bit to create a groove in the screw, effectively unscrewing it. Alternatively, you can try using the drill as a clamp by opening the chuck and placing it around the screw. Tighten the chuck, then run the drill in reverse to turn the screw counterclockwise.
• Cut a groove with a hacksaw blade: Create a straight groove in the metal of the screw, then use a standard screwdriver to turn and remove it.
• Weld a nut: If you have welding equipment, you can weld a nut to the remaining portion of the screw. This provides a new grip for turning the screw out.
• Use a bolt extractor: These are designed to be counter-threaded, so you drill a hole down the screw and then screw in the extractor, which will help to remove the stuck screw.

Step 5: Repair and Patch the Wall

Once you've successfully removed the broken screw and anchor, it's time to repair the wall. Depending on the extent of the damage, you may need to use patching spackling or hydraulic cement to fill any holes or cracks. Sand the area if needed and then repaint to match the surrounding wall.

Remember to be patient and persistent throughout the process, as removing a broken screw from a wall anchor can take time and effort. With the right tools and techniques, you'll be able to fix the issue and restore your wall to its original state.

Using a drill to remove a broken screw

Step 1: Assess the Situation

Start by examining the broken screw and anchor. If the screw head is still intact, you may be able to use a screwdriver to remove it. If the screw head is broken or stripped, then you will need to use a drill.

Step 2: Gather Your Tools

You will need a drill, drill bits, and, if possible, a screwdriver bit that fits the broken screw. It is also recommended to have a hammer and needle-nose pliers on hand.

Step 3: Prepare the Drill

Fit the drill with a bit that is slightly smaller than the broken screw. If you have access to a screwdriver bit that fits the screw, you can use that as well. This will help to ensure that you don't strip the screw head further.

Step 4: Start Drilling

Place the drill bit or screwdriver bit into the head of the broken screw. Apply gentle pressure and begin drilling counter-clockwise. This will help to loosen the screw and hopefully back it out of the anchor.

Step 5: Use Pliers if Needed

If the screw is tightly embedded, you may need to use the needle-nose pliers for additional grip. Once the screw is loosened, grip the head of the screw with the pliers and continue turning counter-clockwise until it is removed.

Step 6: Address the Anchor

Once the screw is removed, you can focus on the anchor. If it is a plastic anchor, you may be able to grip it with the needle-nose pliers and slowly turn it counter-clockwise to remove it. For metal anchors, you may need to use a cutting wheel attachment on your drill to cut it away from the surface.

Step 7: Repair the Surface

After removing the broken screw and anchor, you will likely need to repair the surface. This may involve using a spackling compound or drywall patch to fill any holes and then sanding and painting the area for a smooth, finished look.

Remember to always wear appropriate safety gear, including eye protection, when working with power tools. Take your time and work carefully to avoid causing further damage to the surface or injuring yourself.

Fixing concrete damaged by anchors

If you've damaged concrete while installing or removing anchor bolts, there are a few steps you can take to repair the damage. Firstly, you'll need to inspect the damage and decide if the anchor can be tightened, or if it needs to be removed and replaced. If the concrete is severely damaged, cracked, or has pieces missing, it will need to be repaired or replaced before you attempt to insert a new anchor.

If you need to remove the anchor, use a chisel and a hammer to chip away any concrete that may be stuck to it. Then, drill out the anchor. Once the anchor has been removed, clean the hole with a wire brush and vacuum to remove any dust or debris.

Now, you can fill the hole with concrete glue or hydraulic cement. You can also use a concrete patching solution, or a mortar mix with gravel. If you're using new concrete, bear in mind that it won't bond with the old concrete. In this case, you can use a bonding agent to join the new and old concrete.

Once the glue, cement, or patching solution has dried, you can insert a new anchor. If you're using a concrete screw, simply screw it into the hole. If you're using a dowel-style anchor, hammer it into the hole and tighten the nut on top with a wrench.

If you're dealing with a female concrete anchor bolt, you may be able to thread the bolt back into place using a screwdriver and vice grips. Male concrete anchor bolts are more challenging to remove. If the hole beneath the anchor is deep enough, it can be pounded into the ground. Otherwise, it will need to be split with a hacksaw or cut-off wheel, leaving a nub above the ground, which can then be flattened with a hammer or grinding wheel.

Removing an EZ anchor with a broken screw head

Step 1: Assess the Situation

Before you begin, it is important to understand the problem. In this case, the screw head has sheared off inside the EZ anchor, making it difficult to remove. The screw cannot be pulled out because it lacks a head, and the anchor cannot be unscrewed because the broken screw is blocking the screwdriver's path.

Step 2: Gather Your Tools

You will need a few tools to remove the broken EZ anchor successfully. Make sure you have needle-nose pliers, patching spackel, a putty knife, sandpaper, and paint. Additionally, you may require a hammer and a nail punch or a drill with a left-hand thread drill bit.

Step 3: Grip the Anchor

Use the needle-nose pliers to grab onto the sides of the EZ anchor. You may need to push the pliers slightly into the wall to get a firm grip. This step can be challenging, so take your time and be patient.

Step 4: Turn the Anchor Counterclockwise

Once you have a secure grip on the anchor with the pliers, slowly turn it counterclockwise. This action will help loosen and eventually remove the anchor from the wall. Again, this may require some effort and persistence.

Step 5: Replace or Patch the Wall

After removing the broken EZ anchor, you can replace it with a new anchor. If the previous anchor was the largest size, you may need to patch the hole. Use the patching spackel and putty knife to fill the hole, and don't worry about making it perfect. Once it dries, you can sand it down and refill if needed.

Step 6: Finish and Paint

Once the hole is filled and sanded, you can paint over it to match the surrounding wall. This step ensures that the repair blends seamlessly into the existing wall.

It is important to note that if you are unable to get a grip on the anchor with pliers, there are alternative methods you can try. Some people suggest using a hammer and nail punch to solve the problem quickly. Others recommend cutting a slit in the top of the anchor with a Dremmel tool and then using a slotted screwdriver to unscrew it. Additionally, you can try using locking pliers, vise grips, or a drill with a bolt extractor to remove the broken screw.

Remember to work carefully and patiently throughout the process to minimise damage to your wall and achieve a successful repair.

Using pliers to remove a broken screw

Step 1: Choose the Right Pliers

Select a pair of pliers that are suitable for the job. Needle-nose pliers or long-nose locking pliers are often recommended for this task. You can also consider screw-extracting pliers, such as the Knipex TwinGrip or Vampliers. These specialized pliers are designed for removing screws and may provide better grip and leverage.

Step 2: Get a Good Grip

If the broken screw has enough of its head remaining, you can try clamping the pliers directly onto the head. If the head is mostly broken off, you may need to grip the sides of the screw or the exposed screw threads. Push the pliers firmly onto the screw, ensuring a tight grip. You may need to push the pliers slightly into the surrounding material to get a better grip.

Step 3: Turn Counterclockwise

Once you have a secure grip on the screw, slowly turn the pliers counterclockwise. This will help loosen the screw. It is important to work slowly and gently to avoid further breaking or damaging the screw, especially if you are gripping the sides or threads.

Step 4: Apply Steady Pressure

As you turn the screw, apply steady and firm pressure. This will help prevent slipping and reduce the risk of causing further damage. If the pliers start to lose their grip, adjust and clamp them again before continuing.

Step 5: Remove the Screw

Continue turning the screw counterclockwise until it is loose enough to pull out. Depending on the condition of the screw and how much is exposed, you may be able to simply pull it out with the pliers. In some cases, you may need to use a different tool, such as a screwdriver, to finish removing the screw.

Tips and Troubleshooting:

• If the screw is in a delicate material, such as drywall, be extra cautious to avoid causing further damage. You may need to patch and repair the area after removing the screw.
• If the pliers are not providing enough grip, you can try using a rubber band or steel wool. Place the rubber band over the head of the screw and insert the screwdriver into the rubber band before turning.
• For screws with a broken head, you may need to use other tools in conjunction with the pliers. For example, you might need to use a utility knife to expose more of the screw or an awl to help loosen it.
