Abstract: An interference fit screw driver has a polygonal driving surface to impart torque to a corresponding surface in a screw. The end of the polygonal driving surface has a frusto-conical shaped gripping member which fits into an aperture in the screw to create a friction fit between the screw and screw driver.

Abstract: A screw holder mountable on a drive unit having a tubular passage with two axially-aligned sections, each provided with locking and centering elements, such that a screw inserted into such holder can initially only penetrate until the screw head is reliably held and suspended in the first section by the locking elements. The force of the centering and locking elements upon the screw head is overcome when the apparatus is placed on the screw location and an engagement tool coupled to a drive shaft is brought into driving engagement with the screw head, which driving movement forces the locking elements radially outward in response to the axial load upon the screw head and the passage of the screw head therethrough. After the screw head passes through the first section within the tubular passage, the screw shaft is engaged by the centering elements of the second section. The centering elements of the second section are then also forced back as the head of the screw passes therethrough.
