Abstract: A nail for use in a nailing strip, having a non-circular head defined by at least two dissimilar convex curved shapes, the nail having; a nail shank with a point at one end, shank; a first nail head portion at the other end of the shank, lying substantially in alignment with the shank axis, and extending outwardly therefrom on either side of the shank, a second nail head portion formed integrally with the first nail head portion, the second nail head portion being substantially offset relative to the shank, the first nail head portion defining a first generally convex curved shape, and having a central point coincident with an edge of the shank, so that the nails may lie in closely collated relation in a strip, and, the second nail head portion defining a generally convex curved shape extending away from the shank.
