ABSTRACT An anchor bolt is described having an anchor rod which has a screw-threaded portion at one end and a head at the other, which enables the bolt to be torqued-up in use, and an abutment between the head and the screw-threaded end portion. An expansion body is threadedly received on the screw-threaded portion, and a first sleeve member expansible by the expansion body arranged on the rod between the abutment and the expansion body. A second sleeve member is arranged on the rod between the rod head and the abutment, together with a spacer element over which the second sleeve member can slide as the expansion body is drawn axially of the rod, to expand the expansible sleeve member, when the anchor bolt is being set in a receiving socket. The arrangement is such that the bolt can be fully set in the receiving socket, with an object to be clamped thereby pulled hard against the receiving surface before, or just as, the second sleeve member is in contact both with the rod head and the abutment, so avoiding uselessly loading the second sleeve member in an effort to fully clamp the object in place. At the same time the spacer element occupies or substantially occupies the space between the second sleeve member and the rod thus maximizing antivibration efficiency.
