ABSTRACT OF THE DISCLOSURE An axially extending screw pin to be screwed into a tooth has a threaded part and an engagement part with a slot in one end. The slot extends in the axial direction of the pin toward the threaded part with the axially extending surfaces of the slot converging inwardly toward its base which has a concave, semi-circular surface. The converging sides are convex surfaces defining a quarter arc of a circle. A driven member with an engagement projection at one end shaped complementary to the slot, is disengageably connectible with the screw pin. A gripping member is axially displaceable positioned on the engagement projection end of the driven member. The gripping member is freely rotatable relative to the driven member and has resilient gripping tongues for holding a screw pin relative to the driven member. The driven member is mounted in a drive member so that it can be rotated about its axis. With the screw pin held by the gripping member, the engagement projection is inserted into the slot and threads the screw pin into a tooth. When a stop on the screw pin engages the tooth after it has been driven in for a given depth, the engagement projection backs out of the slot discontinuing the driving action. -31-
