Abstract
Screw driver-holder apparatuses, systems and methods are provided and can include a screw and a screwdriver. The screw can include a threaded screw body and a screw head, and the screw head can include a socket and a screw head surface surrounding the socket. The screwdriver can include a hollow sleeve with a longitudinal bore and a first end defining a screw engagement surface and a driving shaft positioned within the longitudinal bore of the hollow sleeve and rotatable relative to the hollow sleeve. The driving shaft can further include a first end extending beyond the first end of the hollow sleeve, a second end opposite the first end, and a stop restricting axial movement of the sleeve towards the second end of the driving shaft. The first end can include a protruding tip adapted for engaging the socket of the screw head.
