Soft steel nails specially designed for attaching horseshoes to hooves. They are generally made with a four-sided, tapered shaft; the tip beveled on the inside, and a head shaped to seat into a horseshoe. A pattern or trademark is stamped into the inside face of the head to make it possible to distinguish the inside from the outside at a glance. Carpenter or masonry nails are not suitable substitutes for horseshoe nails. a.k.a: Horse nails.
