ABSTRACT:
The nail heads of a nail row respectively have two symmetrical oblique insert members respectively formed under the front and the rear side, and each oblique insert member has a horizontal plane and an inclined plane connected to each other. Between the horizontal plane and the flat striking portion of the nail head forms a preset thickness strong enough to resist striking. The inclined plane has its outer side edge connected with one side edge of the nail head to form a sharp nailing portion able to be smoothly nailed in a workpiece. The horizontal plane and the inclined plane are combined with the workpiece by mutual engagement, able to combine work pieces together with great stability and firmness.
