ABSTRACT:
A screw starter has a generally cylindrical tubular sleeve sized for closely receiving the screw head, an open upper end, and an opposite lower end with a closure designed to hold the screw point centered in the sleeve, holding the screw perpendicular to the surface into which the screw is driven. The closure is ruputures to pass the screw and the starter is discarded after use. Diametrically opposed slots in the sleeve admit a wide screw driver blade into engagement with the screw head in the sleeve. Two sleeves can be joined end to end for starting a screw longer than either sleeve alone.
