PURPOSE: An anchor bolt is provided to enable a user to perform a task alone by preventing an anchor bolt from becoming separated from a hole by the movement of a socket. CONSTITUTION: An anchor bolt comprises a bolt(105) and a socket(108). The bolt comprises a sloped head(102), which is inserted into a hole on a wall. The bolt comprises a shaft unit(103) and a screw unit(104) outside the head. The socket comprises a radial slot(107) so that the socket burrows into the hole to generate coupling force while the diameter of the socket is expanded by the head. The bolt comprises a damage preventing unit(110) and a separation preventing unit(111). The damage preventing unit prevents the damage to the screw unit and makes the coupling of the screw easy when the bolt is inserted into the hole. The separation preventing unit makes the socket firmly burrow into the hole and prevents the socket from becoming easily separated from the bolt.
