Step 1: Prepare the Work Area

Before you begin removing the broken bolt, it is essential to prepare the work area properly. Clear any surrounding debris or obstructions that may hinder your access to the bolt. Additionally, ensure you have all the necessary tools and safety equipment on hand.

Step 2: Apply Lubricant

To ease the removal process, apply a penetrating lubricant, such as WD-40, to the broken bolt. Allow the lubricant to sit for a few minutes to work its way into the threads and reduce friction.

Step 3: Use a Center Punch

Next, use a center punch and a hammer to create a small indentation on the broken bolt. This will help guide the drill bit and prevent it from sliding off the bolt’s center while drilling.

Step 4: Drill a Pilot Hole

Choose a drill bit slightly smaller than the diameter of the broken bolt and carefully drill a pilot hole into the center of the bolt. Apply steady and even pressure while drilling to avoid damaging the surrounding material.

Step 5: Insert an Easy-Out

Once the pilot hole is drilled, insert an easy-out or screw extractor into the hole. Make sure it fits securely. Gradually turn the extractor counterclockwise using a wrench or socket set to grip the bolt and loosen it.

Step 6: Apply Heat

If the bolt remains stubborn, you can apply heat to expand the metal and break the bond of corrosion. Use a small propane torch or a heat gun to heat the bolt for a few minutes. Take caution not to overheat or damage the surrounding area.

Step 7: Use Vise-Grips

If the previous steps did not work, you can try using Vise-Grips to remove the broken bolt. Clamp the Vise-Grips onto the exposed part of the bolt, ensuring a firm grip. Slowly rotate the Vise-Grips counterclockwise to release the bolt.

Step 8: Seek Professional Help

If all else fails or if you lack the necessary tools or experience, it may be best to seek professional assistance. A skilled mechanic or a certified technician will have the expertise and proper equipment to remove the broken bolt safely.


Removing a broken bolt requires patience, precision, and the right tools. By following these step-by-step instructions, you can increase your chances of successfully removing that stubborn broken bolt. Remember to work carefully to prevent further damage and always prioritize safety. Happy bolt removing!
