394100 Bolt-grip 7-pc. Bolt Extractor Set, Hcs, Black Oxide

The Irwin Power-Grip bolt extractor set is engineered to remove fasteners that have become difficult or impossible to turn: rounded-off bolts, rusted-tight fasteners, and painted-over bolts. These extractors use reverse spiral flutes that bite into damaged fasteners to break them free, making them essential for mechanics, automotive technicians, and anyone working with corroded or compromised hardware.

Each extractor features a 1/4 inch hex shank that fits most power drills and quick-change adapters, enabling fast, efficient removal. The universal lobular design works on many bolt styles and shapes, so you have one set for multiple fastener types. High-carbon steel construction ensures long-lasting durability through repeated use.
