Abstract:
The invention is directed to a ratcheted wrench for removing threaded fasteners having two ends and a handle extending between them, and two double-sided fastener extraction heads, one at each end, each fastener extraction head driven by a reversible ratchet, the wrenching having at least two and up to four differently sized receiving areas for accommodating differently sized fastener heads, the ratcheted motion permitting the user of the wrench to easily switch to a different sized receiving area by flipping the wrench over and switching the ratchet direction, or by using the other end of the wrench.
