Screw, Stud & Bolt Extractors

Broken bolt extractors are specialized tools designed to remove broken or stripped bolts, studs, screws, pipe, or other fasteners from their threaded holes. These situations often occur when a bolt or screw is overtightened, rusted, or otherwise damaged, making it challenging to extract using conventional methods. Broken bolt extractors are a valuable solution to prevent further damage to the surrounding material and save time and effort during repair or maintenance tasks.

These extractors typically come in a variety of designs, but one common type resembles a reverse-threaded drill bit. The extractor is inserted into a pre-drilled hole in the center of the broken bolt. As the extractor is turned counterclockwise, its reverse threads grip into the damaged bolt and gradually back it out.

Some broken bolt extractors feature a spiral flute design, which helps improve grip and chip removal during extraction. Others may have straight or square flutes for different applications.

Broken bolt extractors are available in various sizes to match different bolt diameters and are commonly sold as individual tools or as bolt extractor sets that cover a range of sizes. They are made from durable materials such as high-speed steel or hardened carbon steel to withstand the forces involved in extracting stubborn fasteners.

It's essential to use the appropriate extractor size and follow the manufacturer's instructions carefully to ensure successful extraction without causing further damage to the surrounding components. Professional mechanics, DIY enthusiasts, and anyone dealing with stubborn broken bolts can benefit from having a set of these specialized tools in their toolbox.

How to Use a Bolt Extractor

1. Drill a hole in the end of the broken part with a heavy-duty left-hand spiral drill.
2. Insert an extractor tool.
3. Using a wrench, grip the exposed end of the extractor and turn in a counter-clockwise motion.

It should be noted that drilling the broken part with a left-hand spiral drill often eliminates the need for an extractor tool. The counter-clockwise rotation of the drill loosens the bolt stud enough to be removed, but when it doesn't, the extractor tool finishes the job without chewing up or causing the expansion of the object being removed.
