ABSTRACT:
A nail or fastener including a shank having a hollow penetrating portion with a continuous circular blunt end of predetermined width which can be driven into a relatively thick structural metallic member. The penetrating portion of the nail is of a configuration and hardness such that the circular blunt end crimps inwardly to capture a plug of material within the hollow penetrating portion and such plug of material remains joined to the metallic member so as to resist withdrawal of the nail.
