摘要： The dual-sided fasteners as described include the screw-nail fasteners and screw-screw fasteners, and cooperating custom bit tool attachments to insert the dual-sided fasteners. The uniquely designed drill bit tool has a hollow space in the center in which the protruding screw or nail can fit inside allows the crowned shaped tip of the drill bit to reach the screw head and have an interlocking connection with the notched of the screw head. The combined use of the dual sided fasteners and cooperating custom bit tool attachments allow the construction of blind joins.
