Abstract
The invention describes a device for the assembly and disassembly of a fastening device, more preferably of a rail fastening device on a support body, wherein the device is designed as screw adapter and the screw adapter is to be placed on the rail fastening device. The invention is based on developing a device for the assembly and disassembly of a rail fastening device which sits on the fastening device with an accurate fit and largely guarantees automated screwing in and screwing out of the fastening device in existing engagement stages. According to the invention this is achieved in that the screw adapter comprising an engagement pin at its stem, in the contact surface of its main body possesses a centrally arranged recess to accommodate the head of a fastening element, wherein the main body on both sides next to this recess comprises two mounting pockets designed trough-shaped as well as a stop.
