Abstract: An arrangement and method of securing siding to a building and a specialized nail for securing siding to a building are disclosed. The nail comprises first and second elongate shanks and a head connected with respect to the shanks and extending transversely thereto with an outer surface for contact with a hammer during installation of the nail. The method involves providing a first siding panel having an edge and a first slot spaced from the edge by a first distance, hammering the first shank into the building, the first shank positioned in the first slot, and hammering the second shank into the building, the second shank positioned outside of the first slot. The arrangement comprises such a panel fixed to a building with such a nail.

Abstract: A compositely plated, threaded fastener has zinc plating applied to a threaded fastener core and an aluminum plating is applied to the zinc underplating. Optionally, a polymeric top coat can be applied to the aluminum plating for pigmented appearance. The combination of the composite aluminum and zinc platings not only provide the fasteners with improved corrosion resistance but also provide particularly reduced torque load in driving such fasteners, for example, in drilling applications.
