Abstract: A tool for driving fasteners may include a box end which may be configured to interface with a fastener, and a lever arm which may be operably coupled to and may extend away from the box end. The box end may interface with the fastener via an engagement orifice. The engagement orifice may include a plurality of instances of a gripping surface that may extend parallel to respective planar surfaces of the fastener to operably couple the engagement orifice with the fastener such that the fastener may be drivable while avoiding contact with corner portions of the fastener that may be disposed at intersections of the planar surfaces. The plurality of instances of the gripping surface may extend from a start point to a gripping point disposed between about 50% and about 85% of a distance between consecutive corner portions along each of the planar surfaces.
