Abstract

An asymmetrical engineering flooring nail for driving through an exposed surface of this flooring and fully thereinto. The nail defines an elongated shank having a transverse head at one end and a tapered tip at the opposite end; an intermediate portion of the shank includes a plurality of pairs of opposite teeth: Each transversely registering pair of opposite teeth are lengthwisely offset relative to one another by a small acute angle relative thereto; the number of first teeth on one side of shank is greater than the number of second teeth on the opposite side thereof, so that a smooth toothless upper side portion of said shank portion corresponds to the shank side of said second teeth is longer than that of the first teeth. Each of the opposite teeth forms an edge tooth, extending transversely outwardly beyond the longitudinal plane of the corresponding edge of the shank, and a trough, extending transversely inwardly through the longitudinal plane of the corresponding edge of shank, wherein the pitch and depth of each tooth will vary from one another of the teeth, in such a way as to optimize the features of the nail according to the hardwood flooring material.
