PURPOSE: An anchor bolt fixable by nut fastening is provided to reduce working hours, to improve working condition and to reduce neglect accident since the fixing of an anchor bolt is possible with only nut fastening by the preventing of the no-load operation of an expanded pipe, a bolt and a reinforcing member. CONSTITUTION: An anchor bolt fixable by nut fastening comprises a bolt(110) and an expanded member(130). The bolt is inserted into the hole of a concrete structure. A screw(111) is formed on one side of the bolt and a wedge(112) is formed on the other side of the bolt. The expanded member comprises an expanded pipe(132), which can be expanded by a cutting part(131). A protrusion(140) is formed on the wedge of the bolt. Since the cutting part is blocked by the protrusion and the no-load operation of the expanded member is prevented in fastening a nut, the expanded member is expanded by only the fastening of the nut and is fixed to a concrete hole.
