Abstract:
A new and improved fastener, uniquely adapted for securing together vertically oriented stud members and horizontally oriented track members of wall framework structures, comprises a forwardly extending pointed tip portion having a tangent ogive configuration so as to facilitate fast and accurate penetration into and through thin gauge sheet metal members without causing any excessive enlargement of the apertures formed within the thin gauge sheet metal member, and a shank portion which comprises a lower, spiral-threaded shank portion which facilitates the ease of penetration of the fastener into and through the thin gauge sheet metal members, and which causes a mating thread to effectively be extruded within the thin gauge sheet metal members. The upper shank portion may alternatively comprise a plurality of axially contiguous, annular flute members, or a plurality of nibs interposed between the spiral threads, which have oppositely disposed or oriented faces for facilitating the penetration of the fastener into and through the apertured thin gauge sheet metal members, and for engaging the annular rim regions of the thin gauge sheet metal members, which surround the apertures formed within the thin gauge sheet metal members, so as to significantly enhance the clamping forces and pull-out resistance values of the fastener with respect to the thin gauge sheet metal members.
