Details:

The GEARWRENCH Bolt Biter™ nut drivers are designed with innovative features to grip rounded out, frozen, and damaged fasteners. The revolutionary Bolt Biter™ gripping design is bi-directional, seats quickly and safely on fasteners, and removes easily from fasteners after use. Bolt Biter™ nut drivers offer an impact ready option that delivers extreme durability. Bolt Biter™ technology redefines extraction by gripping rounded fasteners rather than cutting into them, which means these nut drivers last 50x longer than competition.
