How to Remove a Broken Bolt: 10 Steps
A broken bolt can cause a significant amount of frustration and can bring any project to a screeching halt. Fortunately, there are ways to salvage the situation and remove that stubborn bolt. Here are 10 steps to help you tackle this problem effectively.
1. Assess the situation: Take a close look at the broken bolt and the surrounding area to determine the best course of action. Consider factors such as accessibility, rust, and how much of the bolt remains exposed.
2. Gather necessary tools: You’ll need a range of tools, including penetrating oil, pliers, a hammer, screw extractors, a drill, left-handed drill bits, and safety goggles.
3. Apply penetrating oil: Spray the area with penetrating oil and let it soak for several minutes. This will help loosen rust and other debris that may be holding the broken bolt in place.
4. Attempt extraction with pliers: If enough of the bolt remains exposed, grip it firmly with locking pliers and try turning counterclockwise to remove it.
5. Hammer: If there isn’t sufficient grip for pliers but the broken bolt is raised above the surface, carefully tap on it with a hammer in an attempt to loosen it further.
6. Prepare for drilling: If extraction by pliers or hammer isn’t possible, you’ll need to drill into the bolt for removal. First, identify the center of the bolt and mark it with a punch to create an indentation as a starting point.
7. Drill: Wearing safety goggles, begin drilling into the broken bolt using a left-handed drill bit (left-handed bits turn counterclockwise). Start with smaller sizes first, then gradually increase as necessary.
8. Screw extractor: When you’ve drilled deep enough into the broken bolt (usually about 1/4-3/8 inches), insert your screw extractor into the hole you’ve drilled. Turn the extractor counterclockwise, and as it spirals in, it should grip the bolt and start to back the bolt out.
9. Remove the broken bolt: Keep turning the screw extractor until the broken bolt is fully extracted from its hole.
10. Clean up: Once the broken bolt is removed, thoroughly clean the threaded hole using a tap or thread chaser to restore its original condition. This will ensure that a new bolt can be installed properly without any complications.
By following these steps meticulously, you will successfully remove a broken bolt and continue your project with minimal disruption. Patience and attention to detail are crucial during this process. Good luck!
