A wrench socket includes first and second ends spaced along a longitudinal axis. The first end includes a recessed indicia area formed in an outer peripheral wall face of a peripheral wall thereof. Size indicia extends outward from a bottom wall of the recessed indicia area and is integrally formed from a single homogenous material with the peripheral wall as a single continuous monolithic piece. The size indicia has a top face extending not beyond the outer peripheral wall face. The radii of the bottom wall and the top face are larger than a radius from the longitudinal axis to the outer peripheral wall face. Centers of curvatures of the bottom wall and the top face are located outside the longitudinal axis.
