Abstract

A screw for use concrete and hurricane applications includes a head end, a shank and a tapered end. A high thread begins on the tapered end, extends onto the shank and terminates at a first axial location along the shank, wherein the high thread defines a high peripheral edge, and at least a first helical portion of the high peripheral edge includes a plurality of notches and the first helical portion extends from on or proximate to the tapered end and substantially to the first axial location. A low thread begins on the tapered end, extends onto the shank and terminates substantially at the first axial location such that an axial length of the low thread is substantially the same as and contiguous with an axial length of the high thread. The low thread defines a low peripheral edge that is free of any notches.
