The OEMTOOLS 10-pc Spiral Type Bolt Extractors Set, No. 22988, is designed to remove rounded-off, rusted-over, or painted-on bolts. The bolt extractors have a reverse spiral flute that bites down on the bolt to ensure maximum gripping power to bust free stubborn or damaged bolts. The more torque applied, the harder the extractors grip the fastener. The universal design works with all fastener types, and the 3/8" square drive can be used with impact wrenches and hand or air ratchets. The bolt extractors also feature hexagonal flats to use with flat wrenches, pliers, adjustable wrenches, sockets, or locking pliers. The set includes SAE sizes: 5/16", 3/8", 7/16", 11/16", 1/2", 9/16", 3/4", and 5/8".
