Abstract
A driving tool member includes a driving shank having one or more blades each having one or more engaging surfaces, for engaging into and for driving driven members. For example, the driving shank may include a conventional flat blade or head, or a Phillips head, or a driving member having four engaging surfaces. The driving shank includes a number of projections extended outwardly from the engaging surfaces of the blades, to form a number of recesses between the projections, and to form a serrated anti-slip structure, to solidly engage with the driven members, and to prevent the driving shank from slipping relative to the driven members.
