Rusted exhaust bolts and rounded-off oil drain plugs are common headaches. Bolt extractors make quick work of them. Unlike standard sockets that slip over rounded corners, these sockets feature reverse-spiral flutes inside. As you turn the socket counter-clockwise, the sharp teeth bite into the metal bolt head. The harder you pull, the tighter the tool grips. They are impact-rated and come in precise sizes to fit metric and SAE fasteners.

Frequently Asked Questions
Place the bolt head in a vise and tap the socket extension with a hammer, or use the metal drift pin included in the extractor kit.
No. These are designed for hex bolts. For socket head or Allen bolts, you need internal screw extractors.
Choose a size that fits tight on the rounded head. You may need to tap the socket onto the bolt with a hammer for a solid grip.
Yes. They are made from hardened alloy steel. However, the internal teeth will dull over time if used on hardened bolts.
