This paper is described that in order to put anchor bolts of the above title to practical use, the pull-out tests of anchor bolts with a head were carried out those were embedded, in concrete rectangular prisms with a straight bore and with a dented bore (we said usually "with shear-key") of various size of depth and diameter, and the effect on tensile strength, displacement and shape of concrete failure have been investigated. To summarize the results of experiment, in the case of not "with shear-key", we have clarified the relation between size of depth and diameter and adhesive strength of bore sides, and also have clarified that the tensile strength and the displacement had become unstable by state of bore sides. In the case of "with shear-key", we have obtained the each formura of estimation of the bearing capacity according to the types of failure '. slip out failure, corn failure and rupture of bolt, and we have shown the possibility of practical use of the above titled anchor bolts. And validity of shear key was verified most effective for stability of bearing capacity of anchor bolts.
