This type of decorative nail head is often referred to as clavo, a Spanish term with the literal translation of nail.
Used as accents on items such as cabinets, furniture or doors, these have an individually hand-hammered appearance, and are available with either a disc-like head having a raised pyramidal form or a squared head with eased corners. The rings on the nail shaft are biased for easy entry but difficult withdrawal.
Cast from zinc with steel nail shafts, they are available with black or antique brass finishes. Sizes given are diameter or width. Nail length (projection from head base) varies between about 3/4" and 7/8". The nails can be clipped shorter, if desired.
