Adjustable ratchet

[0009]FIG. 1 illustrates an exploded perspective view of a wrench head 10, in accordance with one or more embodiments of the invention. When assembled (e.g., as shown in FIGS. 2 and 3, discussed below), wrench head 10 may form part of a wrench configured to engage a fastener and drive the fastener rotationally. As can be seen in FIG. 1, wrench head 10 includes a base 12, a pair of jaws 14, a pair of threaded shafts 16, an adjusting ring 18, and a sleeve 20.

[0010]In one embodiment, base 12 runs longitudinally between a face 22 on one end and a drive body 24 formed toward the end of base 12 opposite face 22. Face 22 includes one or more surfaces that are oriented toward a fastener, if the fastener is engaged by wrench head 10. More particularly, in some instances, face 22 includes one or more surfaces that are substantially orthogonal to an axis of rotation about which wrench head 10 drives the fastener. Drive body 24 is formed to be engaged by a handle (not shown) to drive wrench head 1
