How to Remove a Broken Bolt

Have you ever faced a situation where you’re trying to remove a bolt, but it snaps off leaving the threaded part stuck in the surface? This can be frustrating, but it’s a common problem faced by mechanics and DIY enthusiasts. In this article, we’ll guide you on how to remove a broken bolt in a few easy steps.

Step 1: Assess the Situation

Before you begin removing the broken bolt, it’s important to assess the situation. Determine the size of the bolt, its material, and the surface it’s stuck in. This will help you choose the right tools to get the job done.

Step 2: Get the Right Tools

To remove a broken bolt, you’ll need some specialized tools. The essential tools you’ll need include a drill, a tap, and a screw extractor. You may also need a center punch, a hammer, and a wrench.

Step 3: Make a Center Punch Mark

Using a center punch, make a small indentation in the center of the broken bolt. This will help you drill the hole correctly and prevent the drill bit from slipping.

Step 4: Drill a Hole in the Broken Bolt

Using the appropriate drill bit size, drill a hole in the center of the broken bolt. Make sure the hole is deep enough to fit the screw extractor.

Step 5: Insert the Screw Extractor

Insert the screw extractor into the hole you drilled in the broken bolt. Make sure you’re using the correct size of the screw extractor. Use a wrench to turn the screw extractor counterclockwise until the broken bolt starts to loosen.

Step 6: Remove the Broken Bolt

Once the broken bolt has been loosened, use pliers or a wrench to remove it completely. Clean the area around the hole to remove any debris.

Step 7: Clean the Threads

Use a tap to clean the threads of the hole. This will remove any debris or rust that may have accumulated in the hole.

Step 8: Replace the Bolt

After cleaning the threads, replace the bolt with a new one. Make sure the bolt is the correct size and material for the surface it’s being attached to.


– Apply heat to the broken bolt before attempting to remove it. This will help loosen the bolt and make it easier to remove.- Use penetrating oil to loosen the bolt before drilling. This will also make it easier to remove.- Use a left-handed drill bit to drill the hole. This will make it easier to remove the bolt if the screw extractor fails.


Removing a broken bolt can be a daunting task, but with the right tools and techniques, it can be done.
