A screw extractor is a specialized tool used to remove broken or stripped bolts. Here's how to use one:
1. Choose the Right Extractor
- Size: Select an extractor that's slightly smaller than the bolt's diameter.
- Type: There are different types of extractors, including left-hand and right-hand, and those with different tip shapes. Choose the one that best fits the bolt's condition.
2. Drill a Pilot Hole
- Center: Drill a pilot hole in the center of the broken bolt.
- Depth: The hole should be deep enough to accommodate the extractor's length.
3. Insert the Extractor
- Alignment: Carefully align the extractor with the pilot hole.
- Tighten: Gently turn the extractor clockwise to engage it with the bolt.
4. Remove the Bolt
- Counterclockwise: Slowly turn the extractor counterclockwise to loosen the bolt.
- Pressure: Apply steady pressure, but avoid excessive force.
- Reverse: If the extractor starts to slip, reverse the direction briefly and try again.
5. Repeat if Necessary
- Multiple attempts: If the bolt is stubborn, you might need to repeat the process with a larger extractor or try a different approach.
Important Note: Screw extractors can sometimes damage the surrounding material. Be careful and use caution when using this tool.
