5 Methods to Remove a Broken Bolt Without a Drill

Breaking a bolt can be frustrating, especially when you don’t have a drill to remove it. However, there are several methods you can use to safely and effectively remove a broken bolt without a drill. Whether you’re a DIY enthusiast or a professional mechanic, these methods can save you time and money.

1. Use a Bolt Extractor Set: A bolt extractor set is a handy tool that can remove stripped, seized, or broken bolts. These sets come with a range of extractor sizes and a drill bit. Simply choose the appropriate size extractor and place it in the hole. Use a wrench or socket to turn the bolt extractor counterclockwise, and the broken bolt should come out.

2. Heat and Penetrating Oil: Applying heat to a broken bolt can help loosen it. Use a propane torch or a heat gun to heat the bolt for a few minutes. Once it has cooled down slightly, spray penetrating oil on it. The heat will cause the metal to expand and the penetrating oil will help lubricate the threads, making it easier to remove the broken bolt.

3. Tapping with a Hammer: Tapping the broken bolt with a hammer can also help loosen it. Use a center punch to create a small indentation in the center of the bolt. This will help the hammer catch on the bolt and provide more leverage. Gently tap the bolt in a counterclockwise direction with a hammer. The repeated tapping can help loosen the bolt and make it easier to remove.

4. Welding: If you have access to a welder, you can try welding a nut or a piece of metal onto the broken bolt. This will provide a new surface area for a wrench or socket to grip onto. Once the weld has cooled, use a wrench or socket to turn the bolt counterclockwise and remove it.

1. Prepare the bolt: Apply a penetrating oil or lubricant to the broken bolt to loosen it up. Allow it to sit for a few minutes to penetrate and make the extraction easier.
2. Grip the bolt: Use a pair of pliers with a firm grip to grab onto the exposed part of the broken bolt. Make sure you have a good hold on it to apply force when turning it.
3. Turn the bolt: Begin turning the pliers counterclockwise to loosen the bolt. Apply steady and even pressure while turning to prevent the bolt from breaking further.
4. Use an adjustable wrench or spanner: If the bolt is large and difficult to turn with pliers alone, use an adjustable wrench or spanner to provide more leverage. Place the wrench or spanner on the head of the bolt and turn counterclockwise to extract it.
5. Consider vice grips or locking pliers (optional): If the pliers you are using do not provide enough grip or the bolt is still not budging, you may want to consider using vice grips or locking pliers for added grip and torque.
6. Clean the surrounding area: Once the broken bolt is removed, clean the surrounding area to remove any debris or lubricant that may have accumulated.

Extracting a broken bolt with pliers may require some additional effort and patience compared to using a drill, but it is still a viable option. Remember to take your time and apply steady pressure to avoid further damage to the bolt or the surrounding materials.

Use a Screw Extractor Tool

If the broken bolt is sticking out of the surface it is attached to, you can try using a screw extractor tool. This tool is specifically designed to remove stripped or broken screws and bolts.

Here’s how to use a screw extractor tool:

1. Start by selecting the appropriate size of screw extractor tool. The size should match the diameter of the broken bolt.
2. Using a drill or wrench, gently turn the screw extractor counterclockwise into the broken bolt. Apply steady pressure to ensure it digs into the bolt.
3. Once the screw extractor has gripped the broken bolt, continue turning it counterclockwise to remove the bolt from the surface.
4. If the bolt is stubborn and refuses to come out, try tapping it gently with a hammer while turning the screw extractor. This can help loosen any corrosion or rust that may be gripping the bolt.
5. Once the broken bolt is successfully removed, clean the area to remove any debris or residue left behind.

Using a screw extractor tool can be an effective method to remove a broken bolt without a drill. However, it is important to use the right size tool and apply steady pressure to avoid causing further damage.

Apply Heat to Loosen the Broken Bolt

If you have a stubborn broken bolt that refuses to budge, applying heat is a tried and true method to loosen it. By using heat, you can expand the metal surrounding the bolt, making it easier to remove.

Here are the steps to apply heat to loosen a broken bolt:

1. Gather the necessary materials and safety precautions. Before applying heat, ensure you have the following items ready:
   • A heat source (such as a propane torch or oxyacetylene torch)
   • Heat-resistant gloves
   • Safety goggles
   • Fire extinguisher
   • A metal or ceramic object to shield the surrounding area (optional)
2. Clean the area around the broken bolt. Remove any dirt, grime, or debris from the surrounding area using a wire brush or cloth. This will allow for better heat transfer.
3. Aim the flame at the base of the broken bolt. Point the flame directly at the bolt, focusing on the base where it connects to the material. Move the flame around in a circular motion to evenly distribute the heat.
4. Heat the bolt until it glows red or orange. The goal is to heat the bolt to a temperature that causes the metal to expand but not melt. This temperature can range from 600-900 degrees Fahrenheit.
5. Allow the bolt to cool naturally. Once the bolt has been heated, turn off the torch and let the bolt cool down on its own. Do not attempt to cool it down with water or any other rapid cooling method, as this could cause the bolt to contract and become tighter.
6. Attempt to remove the bolt. After the bolt has cooled down, use a wrench or appropriate tool to try and remove it. The expansion caused by the heat should have loosened the bolt, making it easier to turn and remove.

If the bolt still does not come out, repeat the heating process and attempt removal again. In some cases, stubborn bolts may require multiple heating cycles to successfully remove. If all else fails, it may be necessary to use alternative methods like drilling or using a bolt extractor tool.

Tap the Broken Bolt With a Hammer

If the broken bolt is protruding from the surface, you can try tapping it with a hammer to loosen it. This method works best when the bolt is stuck due to rust or corrosion.

1. Safety first: Before you start, ensure that you are wearing safety glasses and gloves to protect yourself from any flying debris.
2. Position the hammer: Hold the hammer perpendicular to the broken bolt, with the head of the hammer resting on the bolt.
3. Tap the bolt: Gently tap the top of the bolt with the hammer. Start with light taps and gradually increase the force if needed.
4. Use penetrating oil: If the bolt is still stuck, you can apply some penetrating oil to help loosen the rust or corrosion.
5. Continue tapping: Keep tapping the bolt with the hammer while applying pressure to see if it starts to come loose. Be patient and take your time.
6. Try using pliers: If the bolt starts to move, you can use pliers to grip onto the bolt and carefully twist it out.

Note: This method may not work if the bolt is broken off flush with the surface or if it is seized due to other factors. In such cases, you may need to try alternative methods or seek professional help.

Use an Epoxy Resin to Remove the Broken Bolt

An epoxy resin can be a helpful tool in removing a broken bolt when other methods are not working. Epoxy resin is a strong adhesive that can bond to various materials, including metal. Using epoxy resin to remove a broken bolt involves a two-step process: applying the resin and then removing the bolt.

Materials Needed

• Epoxy resin adhesive
• Cotton swab or small brush
• Pliers or adjustable wrench

Step 1: Applying the Epoxy Resin

1. Clean the area around the broken bolt to ensure proper adhesion.
2. Mix the epoxy resin adhesive according to the manufacturer’s instructions.
3. Apply a small amount of the mixed epoxy resin directly onto the broken bolt and the surrounding area.
4. Use a cotton swab or small brush to spread the epoxy resin evenly over the bolt and ensure good coverage.
5. Allow the epoxy resin to cure for the recommended time specified by the manufacturer. This typically ranges from a few minutes to several hours.

Step 2: Removing the Broken Bolt

1. Once the epoxy resin has fully cured, use pliers or an adjustable wrench to grip the broken bolt firmly.
2. Slowly and steadily, turn the bolt counterclockwise to loosen it.
3. If the bolt is still stuck, apply gradual and increasing pressure while turning to break the bond between the bolt and the threaded hole.
4. Continue turning until the bolt is completely removed.

Note: If the broken bolt is extremely tight or rusted, it may be necessary to repeat the epoxy resin application and removal process multiple times.

Using epoxy resin to remove a broken bolt can be an effective method, especially when drilling is not an option. However, it is important to work with caution and follow the manufacturer’s instructions for the epoxy resin adhesive to ensure safety and success.

Use a Left-Hand Drill Bit

If you have access to a left-hand drill bit, it can be an effective method for removing a broken bolt without using a drill. Left-hand drill bits have opposite cutting direction compared to regular drill bits, which can sometimes cause the bolt to loosen as the bit is drilling into it.

Follow these steps to use a left-hand drill bit:

1. Prepare the necessary tools: Gather a left-hand drill bit set suitable for your bolt size, a suitable size drill chuck, and a drill with a reverse feature.
2. Secure the broken bolt: Use a pair of pliers or a wrench to securely grip the broken bolt.
3. Select the appropriate drill bit: Choose a left-hand drill bit slightly smaller in diameter than the broken bolt.
4. Insert the drill bit into the drill chuck: Insert the left-hand drill bit into the drill chuck, making sure it is securely tightened.
5. Set the drill to reverse: Set the drill to reverse mode, which will cause the left-hand drill bit to rotate counterclockwise.
6. Position the drill bit: Position the drill bit tip precisely in the center of the broken bolt.
7. Start drilling: Firmly press the drill bit into the broken bolt and start drilling. The left-hand rotation of the drill bit will create friction against the bolt, potentially causing it to loosen.
8. Monitor the progress: Keep an eye on the drilling progress and check for any signs of movement or loosening of the bolt.
9. Continue drilling or switch to an extraction method: If the bolt starts to loosen, continue drilling until it is completely removed. If the bolt does not loosen or only slightly moves, consider switching to an alternative extraction method.

Note that using a left-hand drill bit may not always be successful, especially if the bolt is severely corroded or stuck. In such cases, it is recommended to consult a professional for more advanced removal techniques.

Apply Penetrating Oil to the Broken Bolt

One effective method to remove a broken bolt without using a drill is by applying penetrating oil to the bolt. This method works by loosening the rust or corrosion that may be causing the bolt to be stuck. Here are the steps to follow:

1. Gather the necessary materials: To apply penetrating oil to the broken bolt, you will need the following:
• A can of penetrating oil
• A small brush or spray nozzle
• A rag or paper towel
2. Clean the surrounding area: Before applying the penetrating oil, it is essential to clean the area around the broken bolt. Use a rag or paper towel to remove any dirt, grease, or debris. This step ensures that the penetrating oil can reach the bolt effectively.
3. Apply the penetrating oil: Shake the can of penetrating oil to mix the ingredients. Then, using a small brush or the spray nozzle, apply the oil directly to the broken bolt. Make sure to coat the entire bolt with the penetrating oil.
4. Let it sit: After applying the penetrating oil, allow it to sit for several hours or even overnight. This will give the oil time to penetrate the rust or corrosion and loosen the bolt.
5. Attempt to remove the bolt: Once the penetrating oil has had enough time to work, attempt to remove the broken bolt using a wrench or socket. The lubrication from the oil should make it easier to turn the bolt and remove it.
6. Repeat if necessary: If the bolt does not come loose on the first attempt, you may need to repeat the process. Reapply the penetrating oil and allow it to sit before trying to remove the bolt again.

Applying penetrating oil to a broken bolt can be a simple and effective method for loosening it. However, it is important to exercise caution and use the proper tools to prevent any damage to the surrounding area or injury to yourself.

Utilize a Nut and Bolt Technique

If the broken bolt has enough threads exposed, you can use a nut and bolt technique to remove it. This method involves using a larger-sized bolt and a nut to grip onto the broken bolt and remove it.

Here’s how you can use the nut and bolt technique to remove a broken bolt without a drill:

1. Inspect the broken bolt and determine the thread size.
2. Find a larger-sized bolt with the same thread as the broken bolt.
3. Thread the larger bolt into the hole where the broken bolt was.
4. Tighten a nut onto the exposed threads of the larger bolt.
5. Use a wrench or socket to hold the larger bolt in place while turning the nut counterclockwise.
6. The nut will catch onto the broken bolt and, as you turn the nut counterclockwise, it will slowly unscrew the broken bolt from the hole.
7. Continue turning the nut until the broken bolt is fully removed from the hole.

Note that if the broken bolt is severely stuck or the thread size cannot be matched, this method may not work effectively. In such cases, you may need to explore alternative methods or seek professional help.

Using the nut and bolt technique can be a simple and effective way to remove a broken bolt without a drill. However, it requires careful selection of a larger-sized bolt with the same thread as the broken bolt to ensure a proper grip. Take your time and be patient while using this method to avoid damaging the surrounding surfaces or the larger bolt.
