ABSTRACT:
An anchoring bolt including an expansion sleeve and an expander member insertable into the sleeve to expand the latter. The anchoring bolt has an inner thread at the end which faces the end face of the wall of the supporting structure to which an object is to be fastened by the anchoring bolt. A removable spacer is inserted into the borehole of the supporting structure after the anchoring bolt and is engaged with the inner thread thereof so as to determine a distance between the end of the inserted anchoring bolt and the end face of the supporting structure. This distance corresponds to the distance that the expander member is to be drawn into the expansion sleeve.
