An implantation set for implanting a screw in a human or animal body includes a tool and a screw designed to receive the tool. The screw has a tool receiving region into which or onto which a torque transmission region of the tool can be or is inserted or placed to transmit torque. At least one inclined insertion region is formed on the tool receiving region to guide the tool during insertion of the screw. The tool forms at least one centering surface that is matched to the inclined insertion region such that when the centering surface comes into contact with the inclined insertion region, a form fit and force fit is created.
