Removing a stubborn bolt can be a challenging task. While there are many ways to go about it, using a candle is one of the most effective methods. This technique involves heating the area around the bolt and applying candle wax to the threads, allowing the wax to act as a lubricant and loosen the bolt. This method, also known as sweat-soldering, is particularly useful for rusted bolts and can be a great alternative to penetrating oil. By understanding the principles behind this approach and exercising caution when applying heat, anyone can successfully loosen a stubborn bolt using a candle.

What You'll Learn
Heat the area around the bolt with a propane torch
If you're dealing with a stubborn bolt, one method to loosen it is to heat the area around it with a propane torch. This method is particularly useful for rusty bolts. Before you begin, ensure you are wearing protective clothing, including gloves, eyewear, and non-flammable clothing for your arms and neck. It is also important to work in a well-ventilated area or set up a fan to avoid inhaling any toxic fumes. Additionally, keep a fire extinguisher nearby as a safety precaution.
When using a propane torch, the goal is to heat the nut, causing it to expand slightly and loosen its hold. It is recommended to heat the nut consistently until it is almost red-hot, but be careful not to overheat it to the point of melting or shearing. Keep in mind that the nut and stud will remain hot for a long time, so exercise caution when handling them. Direct the propane torch at the nut for about ten minutes, ensuring that only the nut and female threads are heated, if possible, and not the bolt's male threads.
During the heating process, you may also apply a penetrating oil or lubricant to the nut and threads. This combination of heat and lubrication can work better than using either method alone. The heat helps to thin the oil, and through capillary action, the oil is drawn into the threads, making the bolt easier to remove. You can repeat the process of heating and applying lubrication as needed.
After heating and lubricating the nut, you can try to unscrew it. For extremely tight bolts, you may need to use a hammer to gently tap the bolt a few times to help break it loose. This process of heating, lubricating, and tapping may need to be repeated several times until the bolt finally loosens.
Using a propane torch to loosen a bolt can be an effective method, but it requires patience and caution. Always prioritize safety and work in a well-ventilated area to avoid any potential hazards.

Apply candle wax to the bolt threads
To loosen a bolt with candle wax, begin by heating the area around the bolt with a propane torch. Get it red-hot on at least three sides of the bolt hole. Once it's red, the bolt will come out easily. If the bolt starts to get stuck, reheat it.
Next, apply candle wax to the bolt threads. Hold a candle to the threads, and the wax will be sucked into the opening around the threads. Alternatively, melt some wax near the threads. The wax will act as a lubricant.
You may need to repeat the heating and candle application a few times. Once the bolt is removed, let the area cool down naturally. Then, chase the threads and lubricate them with antiseize.
Before attempting to loosen the bolt, clean the bolt threads with a wire brush to remove any rust.

Use a wire brush to clean the bolt
When dealing with a stubborn bolt, it's important to clean it thoroughly before attempting to loosen it. One way to do this is by using a wire brush to remove any rust, dirt, or debris that may be preventing the bolt from turning.
To use a wire brush effectively, start by brushing away any loose rust or dirt from the bolt and its surrounding area. Pay close attention to the bolt's head and threads, as these areas tend to accumulate the most debris. If the bolt is heavily soiled or greasy, you may need to use a degreasing agent or a parts washer to remove the grime. You can also try using a pipe cleaner or a small wire brush to clean the bolt hole, ensuring that it is free from any obstructions.
Once the bolt is relatively clean, you can use a wire brush to focus on the threads. This step is crucial, as clean threads will allow your tools to grip the bolt more effectively. If you have access to a wire wheel on a bench grinder, this can be an efficient way to clean the threads. Alternatively, you can use a wire brush drill attachment mounted on a power drill or die grinder to reach the threads effectively. Remember to wear safety glasses when working with wire wheels or brushes to protect your eyes from any flying debris.
In some cases, you may need to repair the hex portion of the bolt before attempting to loosen it. After cleaning the bolt head with a wire brush, you can weld an appropriately sized nut onto the bolt head. This provides a new gripping surface for your wrench, making it easier to apply torque and loosen the bolt.
By taking the time to clean the bolt and its surrounding area with a wire brush, you can improve your chances of successfully loosening the bolt without causing damage to its threads or surrounding components. Remember to work carefully and patiently, as rushing the cleaning process may lead to accidents or further complications.

Use a breaker bar for leverage
If you are struggling to loosen a bolt, one method you can try is to use a breaker bar for leverage. Breaker bars are a type of long-handled socket wrench without a ratcheting mechanism. The long handle gives you more leverage and lets you exert more force to loosen the bolt.
To use a breaker bar effectively, follow these steps:
First, assess the situation and plan carefully. Is the bolt worth saving, or would it be easier to simply break it and replace it? Smaller fasteners such as body bolts and screws often cannot be saved. If the bolt is salvageable, start by removing as much rust from the threads as possible using a stiff wire brush.
Next, select the appropriate tools for the job. Avoid using open-end wrenches, as these are likely to round off the flats of the nut. Instead, opt for a six-point box end wrench, which is less likely to cause damage. Ensure that your wrench is the proper size for the bolt you are trying to loosen.
Now, you can begin to apply force to the breaker bar. Lean into the long handle and use your body weight to increase the amount of force applied to the bolt. Rock the wrench back and forth to break the binding force.
If you are still unable to loosen the bolt, you may need to apply a penetrating oil or liquid thread loosener to reduce the torque required to overcome the rust bond. Soak the bolt and threads with the penetrating oil and allow it to work its way into the rust. Then, try again to loosen the bolt with the breaker bar.
By following these steps and using the breaker bar for leverage, you should be able to successfully loosen most stubborn bolts without causing damage to the bolt or surrounding components.

Use an air hammer to shock the bolt loose
Using an air hammer is a great way to loosen a stubborn bolt. This method involves using a hammer to create a shock that loosens the bolt. It is a relatively new method that has proven to be very effective.
To use an air hammer to loosen a bolt, start by tuning the air pressure to low pressure. This will create a nice vibrating but strong force that is strong enough to loosen the rust. You will know that you have the correct air pressure when the air hammer emits a distinct hum.
If the bolt is still not loosening, try using a blunt or pointed tip on the head of the bolt with full PSI to the tool. This will deliver a rapid series of hammer blows that will mechanically break up the rust. For even better results, apply penetrating oil to the bolt before using the air hammer.
While using an air hammer can be very effective, it is important to exercise caution. Excessive pounding or bad aim can cause problems, and there is a risk of damaging the threads or breaking something else. Additionally, if you are working with aluminum or cast iron threads, be careful not to use too much force as you may end up stripping the hole.
There are other methods to loosen a stubborn bolt as well. These include using heat and penetrating oil, adding a new nut to the old bolt head, and using a breaker bar or impact gun to increase leverage and force.
