Abstract
An anchor bolt assembly includes an axially elongated bolt and an axially elongated expanding sleeve laterally encircling the bolt. The sleeve is axially slotted from its leading end. The bolt includes an axially elongated cylindrically shaped shank with a frusto-conical section at its leading end and means for attaching a load to the bolt at its trailing end. A stop extends axially outwardly from the leading end of the frusto-conical section. In the axially extending region of the slots, the outer surface of the sleeve has an axially extending reduced diameter section.
