IRWIN Tools 394001 Hanson Bolt-Grip Bolt Extractor Base Set contains five of the most commonly used bolt extractor sizes and are designed to easily remove rounded off, rusted-over or painted-on bolts. The Bolt-Grip bolt extractors feature reverse spiral flutes that bite down on the bolt to ensure maximum gripping power to break free bolts in almost any condition.
