Engineered to solve the toughest fastener removal challenges, the GearWrench 88690 Bolt Biter™ Impact Extraction Socket Set redefines what extraction tools can do. Designed in collaboration with professional mechanics and industrial technicians, this 28-piece set features innovative tapered flutes and bi-directional gripping surfaces that allow users to remove or install damaged fasteners with ease.

The dual-size sockets work with both SAE and metric fasteners, while the minus-size sockets fit a wider range of worn or rounded bolts. Built from chrome molybdenum alloy steel and finished with black oxide coating, these sockets deliver up to 10x longer impact life and 5x greater torque output than traditional extraction sockets.
