Abstract
Ratchet wrench gears, for use in standard and pneumatic ratchet wrenches include adjustable jaws that may grip a fastener on at least four sides. The jaws travel on tracks or rails and open and close by means of threaded, floating-cams, which urge upon a protruding cam portion integral to the jaw body. The cams are driven axially by turning a threaded-stem-disc, which may comprise a hollow center, thus allowing for a 'through-hole' feature. Various, optional compression-spring means are included to continually bias jaws toward an open position.
