SATA BoltBiter fastener extraction tools are ideal for loosening rusted, rounded or stripped screw heads, nuts and bolts. The sockets have innovative tapered flutes that ensure easy seating onto a damaged fastener, and their hexagonal base allows use with impact guns, ratchets, wrenches or pliers. The bi-directional design means the BoltBiter can tighten any fastener just as easily as it can remove it. The ability to re-use a damaged fastener makes the BoltBiter the perfect tool for specialised components.
