An anchor bolt assembly includes an anchor bolt and an expansion sleeve. The anchor bolt has a leading end and a trailing end and includes a cylindrically shaped body extending from the trailing end toward the leading end. A frusto-concial part extends from the leading end toward the trailing end. A reduced diameter part interconnects the adjacent ends of the body and the frusto-conical part. The reduced diameter part has a diameter smaller than that of the cylindrically shaped body and equal to the minimum diameter of the frusto-conical part. The expansion sleeve is fitted onto the reduced diameter part by deforming it inwardly into partial surface contact with the reduced diameter part. The expansion sleeve has at least one deformable web permitting it to be expanded radially outwardly for anchoring the bolt in a borehole.
