ABSTRACT:
A screw starter device for temporarily holding a screw while starting it into a substrate is a truncated conical rigid tubular member that tapers downwardly from its proximal end portion to the distal end portion. A first arcuate concentric opening in its side is defined by a first proximal transverse edge, a first distal transverse edge and a first pair of longitudinal edges and there is a second arcuate concentric opening similar to, but smaller than and distal of the first opening. A first longitudinal slot through the side of the member extends from the first opening to the second and a second longitudinal slot smaller in width than the first extends from the second opening to the distal end of the member.
