The present invention relates to an insert bolt, and more particularly, to an insert bolt having an anti-turn function, in which one-way teeth are formed on a bottom surface of a bolt head constituting the insert bolt, such that a bolt shaft can turn only in a clockwise direction when casting concrete, thereby preventing the bolt shaft from loosening from a connecting rod. The insert bolt of the present includes: a bolt shaft, a spring coupled to an outer side of the bolt shaft to perform an elastic function, a sliding movement member coupled to the outer side of the bolt shaft and coupled to a lower part of the spring to perform a sliding movement, a supporting rib member positioned in a lower part of the sliding movement member and supporting the sliding movement member and a connecting rod connected to a lower part of the bolt shaft, wherein the bolt shaft includes a disc-shaped head part, and a central shaft in a form of a circular cylinder integrally formed in a center part of the disc-shaped head part, wherein the disc-shaped head part has one-way, a lower part of the central shaft has a screw thread, and the one-way teeth includes an inclined surface and a vertical surface, such that, when an external pressure is applied due to concrete casting, the concrete casting pressure is dispersed through the inclined surface and the concrete casting pressure is aggregated through the vertical surface such that a rotating force is created only in a direction in which the bolt shaft tightens onto the connecting rod.
