ABSTRACT:
An expansion dowel assembly for use in undercut bores in a receiving material includes an axially extending anchor bolt with a load application section at a trailing end region of the bolt and an expansion cone at a leading end region thereof. An expansion sleeve followed by a guide sleeve are arranged between the leading end region and the trailing end region of the anchor bolt. A component to be secured for a surface of the receiving material is centered by the guide sleeve and any lateral loads generated by the component are absorbed by the guide sleeve. The guide sleeve fits around a trailing end region of the anchor bolt and has an annular flange at its trailing end extending laterally outwardly from the guide sleeve and arranged to bear against a surface of the component.
