Effective Techniques for Extracting a Stripped Screw from Metal- A Step-by-Step Guide

How to Get a Stripped Screw Out of Metal

Screws are an essential part of metalwork and construction projects, but they can sometimes become stripped, making it difficult to remove them. Stripping occurs when the screw head or threads become damaged, preventing the screw from being turned. This can be a frustrating problem, but with the right tools and techniques, you can successfully remove a stripped screw from metal. In this article, we will discuss various methods to help you get a stripped screw out of metal.

1. Use a Screw Extractor

A screw extractor is a specialized tool designed to remove stripped screws. It features a spiral cutting edge that fits into the stripped threads and cuts them out. To use a screw extractor, follow these steps:

1. Choose the correct size extractor for your screw.
2. Apply a lubricant, such as cutting oil or WD-40, to the screw and extractor.
3. Insert the extractor into the stripped screw and turn it counterclockwise to cut the threads.
4. Once the threads are cut, use a pair of pliers or a wrench to remove the screw.

2. Apply Heat

Applying heat to the stripped screw can expand the metal and make it easier to remove. Here’s how to do it:

1. Use a soldering iron or a heat gun to heat the screw head.
2. Allow the heat to spread evenly across the head.
3. Once the head is hot, use pliers or a wrench to grip the screw and turn it counterclockwise.
4. If the screw is still difficult to remove, repeat the heating process and try again.

3. Use a Hacksaw

If the screw is in a tight space or if you don’t have access to other tools, a hacksaw can be a good alternative. Here’s how to use it:

1. Cut the screw head off with a hacksaw, being careful not to damage the surrounding metal.
2. Once the head is removed, you can use pliers or a wrench to remove the screw.
3. If the screw is still stuck, file down the threads and try again.

4. Drill Out the Screw

If all else fails, you can drill out the stripped screw. This method is more destructive and may require some additional work to repair the hole, but it can be effective. Here’s how to do it:

1. Choose a drill bit slightly smaller than the diameter of the screw.
2. Drill into the center of the screw, being careful not to drill too deep.
3. Once the bit is securely in place, use a screw extractor or pliers to remove the remaining screw material.
4. Clean out the hole with a wire brush or sandpaper.

Conclusion

Getting a stripped screw out of metal can be challenging, but with the right tools and techniques, you can successfully remove it. Whether you choose to use a screw extractor, apply heat, use a hacksaw, or drill out the screw, it’s important to be patient and take your time. With a bit of practice, you’ll be able to handle stripped screws with ease.
