Abstract

The utility model discloses a theftproof screw, which aims to provide a screw structural design for preventing the screw from being unscrewed and taken out by other tools. The main feature of the screw is that a cylinder (1) is equipped in an inner hexagonal groove (3) and located in the center of the inner hexagonal groove. The end face of the cylinder aligns with the screw top (4). By equipping the cylinder inside the inner hexagonal groove of the screw, the screw is enabled to resist cooperation with the torsion of a common inner hexagonal wrench. Therefore, if a standard inner hexagonal wrench is applied, the screw will not be screwed or unscrewed. A specially-produced inner hexagonal wrench is needed to deal with the screw. The center of the specially-produced inner hexagonal wrench is provided with a cylindrical hole which cooperates with the theftproof screw. By the specially-produced inner hexagonal wrench, the theftproof screw can be screwed and unscrewed. The theftproof screw which is convenient to use also enhances the safety.
