摘要:
A construction nailing screw is configured to be used in like manner as traditional nails but rotate during driving through threading, providing retention of the construction nailing screw in the construction material(s), and the ability to be removed from the construction material(s) by reverse rotation. The construction nailing screw is characterized by a shank with a head on one longitudinal end, and a tip on another longitudinal end, with external threading that provides minimal friction during installation and mild resistance during removal, and two cutouts extending along the exterior of the shank and through the external threading. The head allows both a manual installation tool and an automatic installation tool to strike the head and drive (install) the nailing screw. The external threading has an upper side with a high pitch relative to the longitudinal axis of the shank, and a lower side with a low pitch relative to the longitudinal axis of the shank.
