GearWrench 86170 8 Pc. Bolt Biter Nut Extractor & Driver Set
GearWrench 86170 Description
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.
