Some Rusted Nuts and Bolts

All Methods for Getting a Rusted Nut Off a Bolt

I know many solutions for this issue, but it is up to you to ascertain which works best for your situation. I have outlined each method to help you make an informed decision. Read to find out more about the various solutions available.

1. Try With Self Grip Wrench or Jaw Pliers

This is an easy solution. Self-grip wrenches and jaw pliers are designed to grip and loosen nuts and bolts. You can use these tools to loosen the nut off the bolt. Make sure to securely grip the nut with the tool and twist it counterclockwise to loosen it.

You can use penetrating oil if the nut is stuck (like WD 40). Penetrating oil is designed to penetrate and loosen rusted nuts and bolts. Spray the penetrating oil on the nut and let it sit for a few minutes. After the oil has done its job, try using a self-grip wrench or jaw pliers to loosen the nut.

2. Heat Up

You can try heating it. Heat the nut with a blow torch or heat gun and wait for it to expand. The heat will cause the nut to expand, which will make it easier to loosen. 

After heating the nut, try to open it with the help of pliers, a pipe wrench, or a self-grip wrench. This method is often regarded as the most effective way to get a rusted nut off a bolt.

3. Resize Nut Shape

If all else fails, you can try reshaping the rusty nut. This process may take some time, as nuts are made of heavy metal. You can do this with a rotary tool or hand steel files. Once the nut is reshaped, you can use jaw pliers, a pipe wrench, or a self-grip wrench to loosen it from the bolt.

4. Use Nut Extractor

This tool is specifically designed to remove rusted nuts. It is easy to use and can be a great solution to this problem. We have a detailed article on using a nut extractor, which you can read for more information.

However, it’s essential to note that if the nuts are too far inside the bolt, it may not be possible to use the nut extractor due to its limited depth.

5. Use Nut Splitter

Using a nut splitter can be costly if you only remove one nut and won’t be using the tool again. Alternatively, you can also try using a Huck Bolt Collar Cutter, which works similarly to a Hydraulic nut splitter.

To use a nut splitter, place the nut into the correct size splitter and turn the handle clockwise until the nut is cut in two parts. This process will separate the rusted nut into two pieces, making removing it easier.

6. Use a Grinder

When I was in a pinch and didn’t have the right tools, I used the grinder to remove a rusted nut. This method works by cutting and separating the nut from the bolt. However, it’s important to note that you need to become an expert in using a grinder to avoid damaging the nuts and bolts. Therefore, it’s best to use this method only if you’re sure you have the expertise.

7. Welding Nut With Hand Wrench Tool or Spanner

Weld the nut with a hand wrench tool or spanner for a unique solution. Start by hitting the nut with a hammer to remove the rust, then apply some penetrating oil and wait for a few minutes. Next, place the hand wrench tool or spanner onto the nut and weld it to the nut. 

Use a hammer to turn the wrench or spanner counterclockwise; hopefully, the nut will come loose. This method ensures that the wrench or spanner won’t come off the nut during the process, and once the nut is removed, the weld can be removed.

Note: If the nut is severely eroded, this method may not be suitable for removing it.

Next Time, Avoid Nut Rust by Doing the Following

I understand that you may experience the same problem again with a stuck, rusted nut, so I am providing some tips to help you avoid this issue in the future. 

Use a Rust Inhibitor or Rust-preventative Coating

To prevent this issue from happening, you can use a rust inhibitor or rust-preventative coating. These coatings form a protective barrier between the metal and the environment, shielding it from the elements that cause rust.

Use Stainless Steel Bolts and Nuts

Stainless steel bolts and nuts are much less prone to rust than other metals. They are an ideal choice for outdoor applications, as they resist corrosion and other environmental factors.

Keep Bolts and Nuts Clean and Dry

To reduce the chance of rust, take the time to keep bolts and nuts clean and dry when possible. This may not be practical in an outdoor or wet place, but the above tips can help.
