A stripped nut is a frustrating problem that can occur during any type of assembly or repair work. When a nut is stripped, it means that the threads have been damaged or worn away, making it impossible to tighten or loosen the nut using conventional methods. Removing a stripped nut can be a tricky task, but it is possible with the right tools and techniques.
The first step to removing a stripped nut is to determine the severity of the damage. If the threads are only slightly stripped, you may be able to use a pair of pliers or a wrench to grip the nut and turn it. However, if the threads are badly stripped, you will need to use more specialized tools. One option is to use a nut extractor. A nut extractor is a tool that is designed to grip the sides of the nut, allowing you to turn it even if the threads are stripped.
Another option for removing a stripped nut is to use a drill to make a hole in the center of the nut. Once you have drilled a hole, you can use a screw extractor to remove the nut. A screw extractor is a tool that is designed to bite into the metal of the nut, allowing you to turn it out. If you are unable to remove the stripped nut using any of these methods, you may need to cut it off using a hacksaw or a Dremel tool.
Identifying the Situation
Determining the severity of the stripped nut is crucial before choosing the appropriate removal technique. Here are some aspects to consider:
Visual Inspection:
Examine the nut closely to assess the extent of damage. If the edges appear mostly intact with only minor nicks, it may be possible to remove it using conventional methods. However, if the nut’s surface is severely deformed or the flats are completely rounded, more specialized techniques may be necessary.
Nut Material:
The type of material the nut is made of can impact the removal process. Softer metals like aluminum and brass are more forgiving than harder materials like steel or stainless steel. Additionally, the nut’s coating, if any, can affect its resistance to certain removal techniques.
Thread Condition:
The condition of the bolt threads can also influence the removal process. If the threads are damaged or stripped, it may be impossible to remove the nut without causing further damage to the bolt. In such cases, it may be necessary to cut the nut off using a rotary tool or hacksaw.
| Severity | Description |
|---|---|
| Minor | Edges mostly intact, minor nicks |
| Moderate | Edges rounded, but flats still discernible |
| Severe | Surface deformed, flats completely rounded |
Gathering Necessary Tools
To effectively remove a stripped nut, it is crucial to assemble the appropriate tools. Ensure you have the following items at hand:
**1. Wrenches:**
- Open-end wrenches in various sizes for gripping the nut from the sides
- Box-end wrenches offer a tighter grip and prevent the nut from slipping
- Adjustable wrenches can accommodate various nut sizes
**2. Pliers:**
| Type | Description |
|---|---|
| Locking pliers | Grip the nut tightly, even if it is stripped, allowing you to turn it |
| Needle-nose pliers | Reach into tight spaces and grip small nuts |
| Vice-grip pliers | Combine the functions of locking pliers and a wrench, providing a strong grip |
**3. Nut Extractors:**
- Designed specifically for removing stripped nuts
- Feature a conical shape with sharp teeth that bite into the nut
- Available in various sizes to fit different nut diameters.
**4. Heat Gun:**
- Apply heat to the nut and bolt, causing them to expand and loosen
- Use caution not to overheat, as it can damage the bolt or nut.
**5. Penetrating Oil:**
- Lubricate the threads of the bolt and nut, reducing friction and easing removal
- Allow sufficient time for the oil to penetrate before attempting to loosen the nut
Using Pliers
If you have a pair of locking pliers, you can use them to grip the nut and turn it off. To do this, simply place the jaws of the pliers over the nut and squeeze them shut. This will lock the pliers onto the nut, preventing it from slipping. You can then use the pliers to turn the nut off.
If you do not have a pair of locking pliers, you can use a regular pair of pliers to grip the nut. However, it is important to use caution when doing this, as the pliers may slip and damage the nut. To use regular pliers, simply place the jaws of the pliers over the nut and squeeze them shut. Then, use your hand to turn the pliers and the nut off.
Here are some tips for using pliers to remove a stripped nut:
- Use the correct size pliers. If the pliers are too small, they will not be able to grip the nut properly. If the pliers are too large, they may damage the nut.
- Place the jaws of the pliers over the nut squarely. This will help to prevent the pliers from slipping.
- Squeeze the pliers shut with even pressure. This will help to prevent the pliers from slipping
- Turn the pliers and the nut off slowly. This will help to prevent the nut from being damaged.

Employing a Nut Extractor
A nut extractor, sometimes referred to as a screw extractor or EZ out, is a specialized tool designed to remove stripped or damaged nuts. It operates by biting into the nut’s surface and providing the necessary grip to unscrew it.
Here’s a detailed guide on using a nut extractor:
1. Select the Correct Size
It’s crucial to choose an extractor slightly smaller than the nut you aim to remove. This ensures a snug fit that enables the extractor to bite into the nut’s surface effectively.
2. Drill a Pilot Hole
Using a drill bit slightly smaller than the extractor, drill a pilot hole into the center of the nut. This hole provides a starting point for the extractor and prevents it from slipping.
3. Insert the Extractor
Align the extractor with the pilot hole and gently tap it into place using a hammer. Ensure the extractor is firmly seated inside the nut.
4. Extract the Nut
a. Reverse Rotation
The most common method involves turning the extractor counterclockwise (lefty-loosey) using a wrench or socket. As the extractor bites into the nut, it will gradually loosen and release its grip.
b. Impact Driver
Impact drivers with hammer action can provide additional force to break loose stubborn nuts. However, use this method with caution, as excessive force could damage the nut or the extractor.
c. Heat and Cool
Applying heat to the nut using a torch can expand it, while cooling it with ice or liquid nitrogen can shrink it. These contrasting temperatures can help break the bond between the nut and the bolt, making it easier to extract.
5. Lubrication
Applying a penetrating lubricant like WD-40 or liquid wrench to the nut can help lubricate the threads and reduce friction, making extraction easier.
Cutting a Slot
This method involves creating a straight slot in the nut using a hacksaw or Dremel tool. Once the slot is cut, you can insert a flathead screwdriver or similar tool into the slot and twist it to loosen the nut.
Step 1: Mark the Nut
Before cutting the slot, mark the center of the nut with a sharpie or pencil. This will ensure the slot is centered and allows for better leverage.
Step 2: Cut the Slot
Begin by securing the nut in a vise or using a nut holder to prevent it from moving. Use a hacksaw or Dremel tool with a thin cutting disc to make a straight slot perpendicular to the bolt axis. The slot should be deep enough to allow for a flathead screwdriver to fully engage.
Step 3: Loosen the Nut
Once the slot is cut, insert a flathead screwdriver or similar tool into the slot and turn it counterclockwise to loosen the nut. Apply steady pressure and gradually increase the force as needed.
Step 4: Remove the Nut
Continue turning the screwdriver until the nut is completely loosened and can be removed by hand. If the nut is still tight, try applying a penetrating lubricant to the slot and allow it to work for a few minutes before attempting to loosen it again.
Using a Reverse Drill Bit
A reverse drill bit, also known as a screw extractor or EZ-out, is a specialized tool designed for removing damaged or stripped nuts. Here’s a detailed guide to using a reverse drill bit:
1. Select the Right Size:
Choose a reverse drill bit that is slightly smaller in diameter than the stripped nut. This ensures a snug fit and prevents the bit from slipping.
2. Drill a Pilot Hole:
Using a regular drill bit, create a small pilot hole in the center of the nut. This will guide the reverse drill bit and help prevent the nut from spinning.
3. Insert the Reverse Drill Bit:
Insert the reverse drill bit into the pilot hole and secure it in the drill.
4. Apply Reverse Rotation:
Engage the drill in reverse mode and apply gentle pressure. As the bit engages with the damaged threads, it will gradually bite into the nut and reverse its rotation.
5. Remove the Nut:
As the drill reverses the nut’s rotation, continue applying pressure until the nut is fully loosened. Once loose, remove it by hand or with a wrench.
6. Additional Tips:
a. Use Lubricant: Apply penetrating oil or lubrication to the nut and drill bit to reduce friction and make the process easier.
b. Start with Low Speed: Begin drilling at a low speed to prevent the bit from skipping or breaking.
c. Apply Steady Pressure: Maintain even pressure on the drill to ensure the bit engages properly with the nut.
d. Use a Bolt Extractor: If the reverse drill bit fails to extract the nut, you may need to resort to using a bolt extractor, which is a more powerful tool designed specifically for removing stubborn nuts.
e. Consider Grinding: In some cases, if the nut is severely damaged, you may need to grind or cut it off using a rotary tool or hacksaw.
Applying Heat
Applying heat can be a highly effective method for removing stubborn stripped nuts, as it can cause the metal to expand and loosen its grip on the bolt. However, it’s crucial to approach this technique with caution to avoid damaging the surrounding components or causing injury.
Materials Required:
• Propane or butane torch
• Heat-resistant gloves
• Safety glasses
Steps:
1. Ensure the surrounding area is clear of flammable materials and take appropriate safety precautions.
2. Wear heat-resistant gloves and safety glasses to protect yourself from burns and sparks.
3. Position the torch flame directly onto the stripped nut and apply heat for a few seconds at a time, gradually increasing the temperature.
4. Avoid overheating the nut, as this can weaken it or damage the threads.
5. Use the wrench to gently attempt to loosen the nut once it has expanded slightly due to heat.
6. If the nut is still stuck, repeat steps 3 to 5, increasing the heat duration gradually.
7. Keep a close eye on the nut and bolt, as excessive heat can cause the bolt to weld itself to the nut, making the situation worse. If this occurs, it’s recommended to use a penetrating lubricant and allow it to soak before attempting to loosen the nut again.
Using a Penetrating Lubricant
Penetrating lubricants are designed to seep into tight spaces and break down rust and corrosion. Applying a penetrating lubricant to the stripped nut can help loosen it and make it easier to remove. To use a penetrating lubricant:
- Apply the lubricant liberally to the stripped nut and surrounding area.
- Allow the lubricant to penetrate for at least 15 minutes.
- Use a wrench or socket to grip the nut and attempt to loosen it.
- If the nut does not loosen, repeat the process and allow the lubricant to penetrate for a longer period.
- Once the nut has loosened, continue to unscrew it by hand.
- Clean the nut and threads with a wire brush to remove any remaining lubricant.
- Apply a small amount of anti-seize compound to the threads before reassembling.
Here is a table summarizing the steps to use a penetrating lubricant to remove a stripped nut:
| Step | Action |
|---|---|
| 1 | Apply penetrating lubricant to the stripped nut and surrounding area. |
| 2 | Allow the lubricant to penetrate for at least 15 minutes. |
| 3 | Use a wrench or socket to grip the nut and attempt to loosen it. |
| 4 | Repeat the process if the nut does not loosen. |
| 5 | Once the nut has loosened, unscrew it by hand. |
| 6 | Clean the nut and threads with a wire brush. |
| 7 | Apply anti-seize compound to the threads before reassembling. |
Tapping the Nut Loose
If you’re dealing with a stripped nut, tapping it loose is a relatively simple and effective method. Here’s a step-by-step guide:
Materials You’ll Need:
- Hammer
- Cold chisel or punch
- Safety glasses
Steps:
- Put on your safety glasses to protect your eyes from flying debris.
- Position the cold chisel or punch against the edge of the stripped nut.
- Tap the chisel/punch lightly with the hammer. Use short, sharp taps to avoid damaging the surrounding area.
- Move the chisel/punch around the nut and continue tapping until the nut starts to loosen.
- Continue tapping until the nut is loose enough to be removed by hand.
- If the nut is still stuck, use a larger chisel/punch and tap harder.
- If the nut still won’t budge, you may need to apply heat using a heat gun or torch. Heat the nut until it’s glowing red, then let it cool. This should make it easier to remove.
- Once the nut is loose, you can remove it by hand or using a wrench.
- If the nut is completely stripped, you may need to drill it out using a drill bit that’s slightly smaller than the nut.
Tips:
- Be careful not to use too much force when tapping the nut. You don’t want to damage the bolt or surrounding area.
- If the nut is rusty or corroded, apply some penetrating oil to it before tapping.
- If you’re having difficulty loosening the nut, try using a pair of pliers to grip the nut and turn it.
Preventing Stripping in the Future
To prevent stripping in the future, follow these tips:
- Use the correct tool for the job. A properly sized wrench or socket will prevent you from overtightening and stripping the nut.
- Apply even pressure. When tightening a nut, apply force evenly around the circumference of the nut. Do not tighten one side more than the other.
- Start slowly. When removing a nut, start by slightly loosening it. Do not force it off in one quick motion.
- Use a penetrating oil. If a nut is particularly stubborn, apply a penetrating oil to it and let it soak in for a few minutes before attempting to remove it.
- Use the double wrench method. If a nut is too tight to remove with a single wrench, try using two wrenches. Place one wrench on the nut and the other on the wrench handle. This will give you more leverage and help you to break the nut loose.
- Use an impact wrench. An impact wrench can be used to remove stripped nuts, but it should only be used as a last resort. These wrenches apply a series of high-force impacts to the nut, which can help to break it loose.
- Drill out the nut. If all else fails, you can drill out the nut. Use a drill bit that is slightly smaller than the diameter of the nut. Drill the bit into the center of the nut and then remove the nut with a pair of pliers.
By following these tips, you can prevent stripping nuts and save yourself a lot of time and frustration.
