Abstract: A nail module for nail attachment of metal tags to hot steel includes a nail and a fracturable carrier. The nail has a pointed shank and a head. The carrier houses the nail and has a delivery end and a female socket end. The carrier delivery end is adapted to receive said nail shank. The female socket end is adapted to receive said nail head. The female socket end also is adapted to receive a mandrel for carrying the module to a driving location in an orientation for driving the nail into a workpiece. The carrier is fractured and releases the nail when the mandrel drives the nail into a workpiece.
