Bolt Biter™ Features and Benefits

Removes rusted or stripped fasteners

High Performance

Typical extraction sockets can make removing rusted or stripped fasteners difficult. Gearwrench Bolt Biter solves all these frustrations. The bi-directional design can tighten or remove any fastener and even allow a damaged fastener to be re-used, making it perfect for specialized components. Bolt Biter even fits a wider range of fasteners, with “minus-size” sockets designed to fit onto fasteners worn down past their original size.

For use with both hand and power tools

Easy Use with Tools

Bolt Biter Extraction Sockets can be used with both hand and power tools as they incorporate a square drive with a hex outer shape for easy use with an impact gun, ratchet, wrench or pliers. Available individually and in 8, 15 or 28-piece sets.

Improved Design

Bolt Biter grips rusted or rounded fasteners instead of cutting into them, which means that these sockets last 10 times longer than typical extraction sockets, which can quickly become dull and unusable. This improved design also seats easily onto the fastener so they don’t get jammed in the socket.


"Tool users will tell you the thing they can’t stand the most is losing time when a tool can’t get the job done. If time lost is money lost, then time saved is money in your pocket, and that’s what the Bolt Biter Extraction Sockets are designed to do better than any other on the market. These sockets address the biggest needs out there while providing a level of durability not typically associated with extraction tools."
