How to Remove a Carriage Bolt That Keeps Spinning

Are you tired of removing a carriage bolt that won’t budge? Don’t worry, you’re not alone. Removing a stubborn carriage bolt can be frustrating and time-consuming, but there are several methods you can use to get the job done.

How to remove a carriage bolt that keeps spinning can be frustrating, particularly when you’re eager to complete a project.

Carriage bolts are designed with a rounded head and a square neck that grips the material as the nut is tightened, allowing for a secure fit. However, if the bolt begins to spin rather than loosen, it can hinder your progress and require a bit of ingenuity to resolve.

In this guide, we will explore practical methods and tips to help you successfully remove a stubborn carriage bolt, ensuring you can carry on with your work without unnecessary complications.

What Will You Need?

Before attempting to remove a spinning carriage bolt, it’s essential to gather the necessary tools and materials. The following are some items you may need for different methods:

• Pliers or locking pliers (such as vice grips)
• Hammer
• Screwdriver
• Drill with drill bits
• Adjustable wrench or socket set
• Saw (for cutting off the bolt if necessary)
• Penetrating lubricant (such as WD-40)

Keep in mind that not all methods will require every item listed here, but having them on hand can be helpful in case one method doesn’t work and you need to try another.

10 Easy Steps on How to Remove a Carriage Bolt That Keeps Spinning

Step 1. Apply Penetrating Lubricant:

Begin by liberally applying a penetrating lubricant, such as WD-40, around the area where the carriage bolt is seated. This type of lubricant is designed to seep into tight spaces and loosen rust or debris that may be causing the bolt to stick.

Allow the lubricant to penetrate for several minutes; in some cases, it may be beneficial to let it sit for longer—up to 15-20 minutes—depending on how rusted or corroded the bolt appears. After this waiting period, you should notice an improvement in the ease of removal, as the lubricant will help reduce friction and rust binding the bolt in place.

Step 2. Use Pliers or Locking Pliers: 

If the carriage bolt spins after applying lubricant, grab a pair of or locking pliers, such as vice grips. Position the pliers around the square neck of the bolt, ensuring a firm grip. While holding the neck in place with the pliers, turn the nut counterclockwise using an adjustable wrench or a socket set. This dual-action approach can help stabilize the bolt while loosening the nut. Just be cautious to apply even pressure to avoid damaging the bolt or surrounding materials. If the bolt still refuses to budge, you may proceed to other methods outlined in the following steps.

Step 3. Tap with a Hammer: 

If the carriage bolt is still spinning after using pliers, try gently tapping the bolt with a hammer. This can help break the bond between the bolt and any rust or corrosion holding it in place. Use a rubber mallet or a regular hammer with a small wood block to prevent damaging the bolt. Tap around the bolt head and square neck to create some vibrations, which can sometimes free up stubborn bolts. After tapping, attempt to turn the nut again with your wrench while stabilizing the bolt with your pliers. If there’s no progress, move on to the next step.

Step 4. Apply Heat: 

If tapping and using pliers have not been successful, applying heat to the area may help expand the metal and break any bonds caused by rust. Heat the bolt carefully for a few minutes using a heat gun or a propane torch. Be cautious not to overheat, as this could damage surrounding materials or cause a fire hazard.

Once heated, allow the bolt to cool down slightly before turning the nut again. The expansion and contraction can help loosen the bolt sufficiently for removal. Ensure you wear appropriate safety gear while handling heat sources.

Step 5. Use a Drill: 

A drill may be the most effective method if the carriage bolt is still stuck after applying heat. Select a drill bit slightly smaller than the diameter of the bolt and carefully drill into the center of the bolt head. This can create a clean break and allow you to remove the bolt easily. Be cautious to maintain control of the drill and apply steady pressure, ensuring not to drill too deeply into the material beneath.

Once you’ve drilled through the head, you may be able to remove the remaining piece of the bolt or even the entire bolt, depending on how it has broken apart. If you encounter resistance, consider switching to a more significant drill bit to widen the hole, which can provide additional leverage for removal.

Step 6. Cut the Bolt: 

If all else fails and the carriage bolt remains firmly in place, consider cutting it off. Using a saw, such as a hacksaw or reciprocating saw, carefully cut through the bolt just above the material’s surface.

Wear safety goggles and gloves to protect yourself from metal shavings and debris. After cutting, you may be able to remove the nut entirely and, if necessary, extract the remaining bolt piece using pliers or a bolt extractor tool. This method should be a last resort, as it can damage the surrounding material if not done carefully.

Step 7. Use a Bolt Extractor: 

If you still struggle with the stubborn carriage bolt, a bolt extractor can be an excellent tool for the job. These specialized tools are designed to grip and remove broken or stripped bolts effectively.

To use it, select the appropriate size extractor that fits snugly into the head of the bolt you’ve drilled or cut. Follow the manufacturer’s instructions to attach the extractor, then apply steady, even pressure while turning counterclockwise.

The extractor’s design will dig into the bolt, allowing you to remove it without damaging the surrounding material. Remember to keep the area clean and clear of debris to give the extractor the best chance of working effectively. If this method proves unsuccessful, you may need to consult a professional for assistance.

Step 8. Consult a Professional: 

If you have exhausted all previous methods and the carriage bolt remains intractable, it may be time to consult a professional. Mechanics or skilled tradespeople have access to advanced tools and techniques that can effectively remove stubborn bolts without causing damage to the surrounding materials.

They can assess the situation and determine the best course of action, which may include specialized equipment or techniques not readily available to DIY enthusiasts. This option might incur additional costs, but seeking professional assistance can save you time and prevent further complications in your project.

Step 9. Prevent Future Sticking: 

Once you have successfully removed the carriage bolt, it’s essential to take preventive measures to avoid similar issues in the future. Start by applying a rust-inhibiting lubricant or anti-seize compound to the new bolt before installation. This will create a protective barrier against moisture and corrosion, helping to ensure that the bolt can be removed quickly next time.

Additionally, periodic maintenance checks on bolts and fasteners in outdoor or high-moisture environments should be considered, enabling early detection of rust or wear. Ensuring proper sealing and covering for outdoor fixtures can also reduce exposure to the elements, contributing to your hardware’s longevity and ease of use.

Step 10. Regular Maintenance: 

Implement a routine maintenance schedule to ensure the longevity and functionality of any fasteners. Inspect all bolts and joints regularly for signs of wear, rust, or corrosion. Cleaning these areas can help remove debris and protect against moisture buildup.

Consider reapplying a rust-inhibiting lubricant or anti-seize compound every six months or after significant weather changes, especially in high-moisture environments. Keeping thorough records of when maintenance tasks are done can also aid in identifying patterns that may need addressing over time.

By following these steps and implementing preventive maintenance measures, you can effectively remove a stuck carriage bolt while preserving the integrity of your project materials.

5 Things You Should Avoid

1. Using Excessive Force: Applying too much force while trying to turn the nut can cause further damage to the bolt and surrounding materials. Instead, use gradual pressure and try methods to loosen the bolt before resorting to brute force.
2. Skipping Safety Gear: Remember to wear safety goggles and gloves, which can lead to injuries from metal shavings, debris, or unexpected tool slips. Always prioritize your safety by using appropriate protective equipment.
3. Waiting Too Long to Act: Delaying the removal process may allow rust or corrosion to set in, complicating the situation further. Address stuck bolts as soon as possible to prevent them from becoming more difficult to remove.
4. Using the Wrong Tools: Employing inappropriate tools can damage the bolt or make it even more difficult to extract. To avoid any mishaps, ensure you use the right sizes and types of tools, such as socket wrenches or pliers.
5. Neglecting to Assess the Damage: Please examine the condition of the bolt and surrounding materials to avoid missteps in the removal process. Continually assess the situation and adapt your approach based on the severity of the issue before proceeding.
