Patent attributes
A fully parametric profile for improved tooling in a tool/fastener system is provided that details a profile from a single proved Wright number, and that improves the contact area across a full spectrum of industry standard tolerances, while preserving safe pockets for fastener corners, thereby providing for increased tool life. The tool profile is based on a central axis and a parametric set of coordinates for flats, transition points, and multiple radii. The profile mates selectively with a set of fasteners having a central axis and a plurality of flat bounding surfaces parallel to the fastener access wherein diametrically opposite pairs of surfaces are parallel to each other and the bounding surfaces intersect in adjacent pairs to form fastener corners.
