The wrench head comprises two jaws each having an engaging surface for engaging with the fasteners. One jaw is generally fixed and connected to a gripping portion formed as a wrench lever and the other jaw is movable relative to the fixed jaw. The wrench head comprises an adjustable means by which the jaws may be spaced apart including a defined maximum spacing dimension between both jaws. The wrench head further comprises an imaginary centerline intersecting both of the jaws through a midpoint of a length of the jaws substantially perpendicular to the engaging surfaces of the jaws as viewed from a side view thereof. And further wherein, each jaw has a width dimension measured at the centerline, and the width dimension of both jaws combined is also defined.
