Abstract
A ratchet wrench (1) with a single-piece jaw (3) having two positions for driving a hexagonal head (4), in particular of a screw or a nut. In each driving position, two opposite surfaces of the head (41,42) are driven by respective protuberances (P2, P7) of the two grips of the jaw, and a supplementary protuberance (P5) is urged in localized support in the front half of an intermediate surface (43) of the head located immediately in front of the rear surface. Thus, the inner profile of the jaw has six main protuberances, with an angular offset of 24 to 28.degree. between two groups of three protuberances.
