Draper Spiral Type Deep Bolt Extractor Set - 11 Piece

The extractors are made from chrome molybdenum steel, known for its strength and durability.

These extractors are designed to be used with any 3/8" square drive tool, including hand ratchets, breaker bars, and compatible air or power tools.

Select an extractor that is slightly larger than the remaining diameter of the damaged bolt or stud you need to remove. Refer to the size markings on the extractors or consult the set's contents list.

Yes, they can be used with 3/8" Sq. Dr. air or power tools, including many impact wrenches, provided you use them carefully to avoid over-torquing and snapping the extractor.

The set is designed for removing deeply trapped and damaged studs, bolts, fittings, threaded pipes, and pins.

The set comes supplied in a robust plastic storage case, which is the recommended method for keeping the extractors organized and protected.

The spiral flute design provides maximum grip by digging into the damaged fastener material as you turn it counter-clockwise, increasing the chances of successful removal.

Ensure the correct size extractor is being used. Hammer the extractor slightly deeper into the bolt material, or try a slightly larger extractor if available. Ensure the bolt is not excessively weakened or cross-threaded.

The bolt may be seized beyond the extractor's torque capacity. Try applying penetrating oil and allowing it to soak. Ensure you are turning the extractor counter-clockwise. Consider using a power tool with a lower speed setting and higher torque.

This is a difficult situation. The broken extractor material will need to be drilled out carefully, often requiring specialized bits. In severe cases, professional assistance may be needed.

If there's enough material, the appropriate sized extractor should still grip. If not, consider alternative methods like cutting a new slot for a screwdriver or using a locking plier style extractor before attempting the spiral extractor.
