Have you ever tried to remove a bolt or screw only to find out that the head is stripped or the threads are damaged? If so, you know how frustrating it can be. But don’t despair! There are a few simple tricks you can try to extract a broken bolt without having to resort to drastic measures like drilling it out.
One of the most common methods for extracting a broken bolt is to use a pair of needle-nose pliers. If the bolt is small enough, you may be able to grip the threads with the pliers and simply unscrew it. However, if the bolt is larger or the threads are damaged, you may need to use a different method.
How to Extract a Broken Bolt
A broken bolt can be a frustrating problem, but it’s one that can be solved with a little patience and the right tools. Here’s a step-by-step guide on how to extract a broken bolt:
- Gather your tools. You’ll need a drill, a drill bit, an extractor, and a hammer.
- Drill a pilot hole. Use a drill bit that is smaller than the diameter of the bolt. Drill a hole into the center of the broken bolt.
- Insert the extractor. The extractor is a tool that has a reverse-threaded screw at one end. Insert the extractor into the pilot hole and turn it counterclockwise until it bites into the bolt.
- Turn the extractor. Use a wrench or pliers to turn the extractor counterclockwise. As you turn, the extractor will bite deeper into the bolt and start to loosen it.
- Remove the bolt. Once the bolt is loose, you can remove it by hand or with a wrench.
Here are some additional tips for extracting a broken bolt:
- If the bolt is rusty, you may need to apply some penetrating oil to help loosen it.
- If the bolt is in a tight spot, you may need to use a longer extractor or a different type of tool.
- Be patient and don’t force anything. If you force the extractor, you may damage the bolt or the surrounding area.

There are a few different types of extractors that you can use to remove a broken bolt:
- Spiral extractors: These extractors have a spiral-shaped head that bites into the bolt as you turn it.
- Conical extractors: These extractors have a conical-shaped head that tapers inward. As you turn the extractor, the cone expands and bites into the bolt.
