How to Remove Broken Bolt Without Extractor
To remove a broken bolt without an extractor, there are several steps you can follow.
First, apply penetrating oil to the broken bolt and let it soak.
This will help loosen the bolt.
Next, use a hammer to tap the surrounding area to dislodge any debris or rust.
Heat the surrounding metal with a torch to make it expand and potentially break the bolt free.
Use a center punch to create a small indentation in the center of the bolt, then drill a pilot hole with a small drill bit.
Gradually increase the drill bit size until the hole is slightly smaller than the bolt threads.
Use a screw extractor or easy out to grip and remove the broken bolt.
If the bolt is still stuck, apply more penetrating oil and try using vice grips or locking pliers to remove it.
If all else fails, seek professional help.

Did You Know?
1. In the late 1800s, Scottish engineer James Nasmyth invented a technique to remove broken bolts called “scaling.” This method involved heating the bolt until it glowed red hot, then quickly cooling it with water, causing it to contract and loosen its grip.
2. A lesser-known alternative to using an extractor is the “left-handed drill bit” technique. By using a drill in reverse (counter-clockwise), the left-handed drill bit can often catch onto the broken bolt and effectively unscrew it while drilling, eliminating the need for an extractor.
3. In some cases, a bolt can be removed by applying heat directly to the surrounding nut or material. This is commonly referred to as “thermal shocking,” as the sudden temperature change causes the metal to expand and contract, allowing for easier extraction.
4. Before the invention of extractors, blacksmiths often resorted to chiseling or filing a groove into the broken bolt to create a notch. This notch would then act as a guide for a chisel or screwdriver, enabling them to unscrew the bolt manually.
5. Sometimes, a mechanical force known as “impact tension” can aid in the removal of a broken bolt. By striking the bolt directly with a hammer or mallet, the sudden impact can help break the rust or corrosion bonds, making it easier to remove.
Apply Penetrating Oil
One of the first steps to remove a broken bolt without an extractor is to apply penetrating oil. This can help loosen the bolt and make it easier to remove. Spray the penetrating oil generously on the broken bolt and let it soak for a few minutes. Allow the oil to seep into the threads and crevices of the bolt. The penetrating oil works by breaking down rust and corrosion, which may be causing the bolt to stick. It also acts as a lubricant, making it easier to turn the bolt out.
When applying penetrating oil, it is important to ensure that the oil penetrates as much as possible. This can be achieved by:
- spraying the oil from different angles
- using a brush or cloth to spread the oil evenly
Let the oil sit for a few minutes to allow it to work its way into the bolt. This step is crucial in ensuring that the broken bolt can be removed smoothly in subsequent steps.
Use A Hammer
Using a hammer can be an effective way to remove a broken bolt without an extractor. After applying penetrating oil, gently tap the area around the broken bolt with a hammer. This can help dislodge any rust or debris that may be preventing the bolt from turning. The tapping motion can help loosen the bolt by breaking up any corrosion that has formed. It is important to be gentle while using the hammer to avoid damaging the surrounding components. Consistent tapping around the bolt can help to gradually dislodge it and make removal easier.
When using a hammer, it is important to strike the area around the broken bolt rather than directly hitting the bolt itself. This will prevent any further damage to the bolt and surrounding materials. Additionally, using a softer mallet or a rubber mallet can help minimize the risk of causing any unintended damage.
- Apply penetrating oil
- Gently tap the area around the broken bolt with a hammer
- Strike the area around the broken bolt, not directly on the bolt itself
- Use a softer mallet or a rubber mallet to minimize the risk of damage
Heat The Surrounding Area
Heating the surrounding area of a broken bolt is another method that can aid in its removal. The application of heat causes the metal to expand, which can help break the seized threads. Use a heat source, such as a torch, to apply heat to the area surrounding the broken bolt. Take caution not to overheat the surrounding area to avoid damaging other components or igniting flammable materials nearby.
To heat the area effectively, move the flame of the torch around the bolt, applying heat evenly. Heat the surrounding metal for about a minute or until it feels warm to the touch. Once heated, let the bolt cool down for a few minutes. The expansion and contraction due to heating and cooling can help break the rust or corrosion that is causing the bolt to stick. This method is especially useful for stubborn and stuck bolts.
Use A Center Punch
When dealing with a broken bolt, using a center punch is a useful technique to help remove it without an extractor. A center punch is a hardened steel tool with a pointed tip that is used to make a small indentation in the center of the bolt. This indentation provides a guide for the drill bit and prevents it from wandering off-center when drilling.
To create the center punch mark, place the point of the center punch firmly on the center of the broken bolt and give it a solid tap with a hammer. The force of the hammer blow should be sufficient to create a small indentation but not so strong that it damages the surrounding material. The center punch mark will act as a pilot point for drilling in the next step.
- Place the center punch on the center of the broken bolt
- Tap the center punch with a hammer to create a small indentation
- Ensure the force is enough to create a mark but not damage the surrounding material
“The center punch mark provides a guide for drilling, preventing the drill bit from drifting off-center.”
Drill A Pilot Hole
Once you have created a center punch mark, the next step is to drill a pilot hole. A pilot hole serves as a starting point for the drill bit and helps guide it into the broken bolt.
Here’s how you can drill a pilot hole effectively:
- Start by selecting a drill bit that is slightly smaller than the diameter of the broken bolt.
- Insert the drill bit into the center punch mark and apply steady pressure to begin drilling.
- It is important to start drilling slowly to ensure accuracy and prevent the drill bit from wandering off-center.
While drilling, ensure that the drill bit is perpendicular to the surface of the broken bolt. This will help ensure that the pilot hole is straight and aligned with the bolt. Apply even pressure and drill steadily until the pilot hole is created.
Be cautious not to drill too deeply, as this can damage the surrounding material or cause the drill bit to break.
Use A Larger Drill Bit
After creating the pilot hole, gradually increase the size of the hole using larger drill bits until the hole is slightly smaller than the outer diameter of the bolt threads. Switch to a larger drill bit and continue drilling out the pilot hole. It is advisable to use a drill bit that is slightly smaller than the threads of the bolt to avoid damaging the surrounding material.
Proceed by increasing the size of the drill bit incrementally, using larger and larger bits until the hole is slightly smaller than the bolt threads. This step is crucial to create enough space for the bolt to be removed without causing any further damage. Take your time and ensure that each drill bit is used slowly and carefully, allowing the chips and debris to be cleared from the hole periodically.
Remember to exercise caution while performing these techniques and always use appropriate safety precautions such as wearing safety goggles, gloves, and working in a well-ventilated area. If, after attempting these techniques, the broken bolt remains stuck, it is advisable to seek professional help from a mechanic or automotive repair specialist who can provide specialized tools and techniques to deal with stubborn and difficult bolts.
Frequently Asked Questions
How do I remove a broken easy out?
Removing a broken easy out can be a tricky task since the hardened steel makes it resistant to regular drilling. One possible method is to utilize high-speed tools like EDM or carbide bits at a speed above 4,000 rpm, which can effectively break down the stubborn steel. Alternatively, burning or grinding the broken easy out might provide a viable solution, similar to the process used for removing broken drill bits. It’s important to exercise caution and, if possible, consult a professional or experienced individual to ensure a successful extraction without causing any further damage.
1. What are alternative methods to remove a broken bolt without using an extractor?
There are a few alternative methods to remove a broken bolt without using an extractor. One method is to use a center punch and hammer to create a small indentation in the center of the bolt. Then, drill a hole into the bolt using a drill bit smaller in diameter than the bolt itself. As you drill, the broken bolt will begin to loosen, and you can use pliers or a wrench to twist it out.
Another method is to use heat to expand the metal around the bolt. You can heat the surrounding area of the bolt using a propane torch, and as the metal expands, it may release the grip on the broken bolt. You can then use pliers or a wrench to turn the bolt out. It’s important to be cautious with this method and avoid overheating or damaging the surrounding materials.
2. Can heat be used as a solution to remove a broken bolt without an extractor tool?
Yes, heat can sometimes be used as a solution to remove a broken bolt without an extractor tool. When a bolt is heated, it expands due to thermal expansion, which can help to break the bond between the bolt and the threaded hole it is stuck in. The application of heat, such as using a torch, can make the metal of the bolt and surrounding parts expand at different rates, causing the bolt to loosen. This technique is often used in combination with other methods, such as applying penetrating oil or using a wrench to turn the bolt while it is still hot.
However, it is important to note that using heat alone may not always be effective, especially if the bolt is severely rusted or the threads are damaged. In such cases, it may be necessary to use more specialized tools like an extractor or seek professional assistance.
3. Are there any specific tools or techniques recommended for removing a broken bolt without an extractor in tight spaces?
When it comes to removing a broken bolt without an extractor in tight spaces, there are a few recommended tools and techniques to consider. One commonly used tool is a left-handed drill bit. This special drill bit is designed to turn in the opposite direction of a regular drill bit, allowing it to catch onto the bolt as it drills into it. As the drill bit catches onto the bolt, it can start to loosen and remove it.
Another technique that can be helpful is using heat to expand the metal around the bolt. By heating the surrounding metal with a torch, such as a propane torch or an induction heater, the bolt may expand slightly, making it easier to remove. This technique is typically combined with other methods, such as using a wrench or pliers to grip and rotate the bolt. Remember to take precautions when working with heat to avoid any accidents or damage to the surrounding area.
