Nail with non-circular head

A nail for use in a nailing strip, said nail having a non-circular head defined by at least two dissimilar convex curved shapes, said nail comprising;

• a nail shank defining a predetermined central axis, and having a point at one end of said shank;
• a first nail head portion at the other end of said shank, lying substantially in alignment with said shank axis, and extending outwardly therefrom on either side of said shank;
• a second nail head portion formed integrally with said first nail head portion, said second nail head portion being substantially offset relative to said shank;
• said first nail head portion defining a first generally convex curved shape, extending equally on either side of said shank, and defining a central point coincident with an edge of said shank, whereby said nails may lie in closely collated relation in a said strip, and,
• said second nail head portion defining a generally convex curved shape extending away from said shank, said first and second nail head portions defining between them a transverse axis, transverse to the axis of said strip, and a further defining longitudinal axis, coincident with the longitudinal axis of said strip, and wherein said nail head dimension along said transverse axis is greater than said nail head dimension along said longitudinal axis.
