Effective Techniques for Safely Removing Stripped Screws from Metal Surfaces

How to Remove a Stripped Screw from Metal

Screws are an essential part of metalwork, but sometimes they can become stripped, making it difficult to remove them. Stripping occurs when the threads on the screw become damaged or worn, preventing the screwdriver from gripping the screw properly. Removing a stripped screw from metal can be a challenging task, but with the right tools and techniques, it can be done successfully. In this article, we will discuss various methods to remove a stripped screw from metal.

1. Use a Screw Extractor

A screw extractor is a specialized tool designed to remove stripped screws. It consists of a threaded rod with a cutting edge that fits into the stripped screw. To use a screw extractor, follow these steps:

1. Clean the stripped screw to remove any debris or dirt.
2. Select a screw extractor with a thread size that matches the stripped screw.
3. Secure the screw extractor in a drill or screw gun.
4. Apply lubricant to the screw and the extractor to reduce friction.
5. Start the drill or screw gun and gently push the extractor into the screw.
6. Continue drilling until the screw is completely removed.

2. Use a Hacksaw

If you don’t have a screw extractor, you can use a hacksaw to remove a stripped screw. Here’s how to do it:

1. Clean the stripped screw to remove any debris or dirt.
2. Mark the center of the screw with a marker or pencil.
3. Place the hacksaw blade on the marked center of the screw.
4. Hold the hacksaw at a 45-degree angle and saw through the screw, being careful not to damage the surrounding metal.
5. Once the screw is cut, use pliers to remove the remaining portion of the screw.

3. Use a Drill and a Screw Extractor

If you have a drill, you can use it in conjunction with a screw extractor to remove a stripped screw. Follow these steps:

1. Clean the stripped screw to remove any debris or dirt.
2. Secure the screw in a vise or clamp to prevent it from moving.
3. Drill a small hole in the center of the stripped screw using a drill bit slightly smaller than the screw extractor.
4. Insert the screw extractor into the drilled hole and follow the steps outlined in method 1 to remove the screw.

4. Use a Hammer and a Punch

If the stripped screw is located in a tight space, you can use a hammer and a punch to remove it. Here’s how to do it:

1. Clean the stripped screw to remove any debris or dirt.
2. Place the punch on the center of the stripped screw.
3. Hold the punch with a pair of pliers and strike it with a hammer to drive the punch into the screw.
4. Once the punch is fully inserted, use pliers to remove the screw.

Conclusion

Removing a stripped screw from metal can be a challenging task, but with the right tools and techniques, it can be done successfully. Whether you choose to use a screw extractor, a hacksaw, a drill, or a hammer and punch, the key is to be patient and take your time. Always remember to clean the stripped screw before attempting to remove it, and use lubricant to reduce friction. With a bit of effort and persistence, you’ll be able to remove the stripped screw and move on to your next metalworking project.
