PROBLEM TO BE SOLVED: To provide a self-supported structure for a foundation anchor bolt, which facilitates self-support of the foundation anchor bolt without extending the entire length of the same. SOLUTION: The foundation anchor bolt 1 is constructed by forming screw threads 11 thereon in a predetermined range from a lower end thereof, and rigidly screwing an anchorage tool 2 which has the shape of a nut with a screw hole 21 onto the screw threads 11 up to their upper end. Then, the anchorage tool 2 of the foundation anchor bolt 1 is mounted on an anchor plate 3 arranged on the ground, and a plate nut 4 is allowed to be screwed on the screw threads 11 portion which has pierced downward through the anchor plate 3, only by a single thread, while the anchorage tool 2 is mounted on the anchor plate 3. In this manner, the foundation anchor bolt 1 is rigidly self-supported on the anchor plate 3.
