The present invention relates to a nail for a horse shoe. The nail comprises a shaft (2) with a head (3) at one end of the shaft. The other end of the shaft is provided with a point (4) opposite of the head. The head is arranged via a neck (5) on the shaft and comprises a convex element (14), where the neck defines a pitch. The present horse shoe nail distinguishes itself over conventional horse shoe nails in that it comprises a convex curvature in an orientation where the curvature extends in a plane defined by both the longitudinal directions of the head and of the shaft. Thus improved directability and wear are provided, amongst other beneficial properties.
