<P>PROBLEM TO BE SOLVED: To provide an anchor nut capable of being easily screw-tightened to a male screw part. <P>SOLUTION: An engagement part capable of engaging a tightening tool from the lower side is formed at the lower end of the body part constituting the anchor nut, and a recess is formed in the outer peripheral side-surface of the body part. By using an electric tool engageable with the engagement part as the tightening tool, the body part can be rotated in the direction of screw-tightening and releasing a female screw part, and the anchor nut can be easily attached to the male screw part of an object to be installed by more easily rotating the anchor nut. Since the recess is formed in a shape capable of suppressing slipping-off, even if the body part is rotated by operating the engaged electric tool, such a risk that a worker or other article touches, hooks, or involves the body part does not occur. <P>COPYRIGHT: (C)2011,JPO&INPIT |
