ABSTRACT:
An expansion anchor sleeve has a leading end and a trailing end, and an expander member is located at the leading end. A threaded member extends through the expansion sleeve and is connected with the expander member in order to draw the latter into the leading end of the sleeve to expand the sleeve. The threaded member has a portion projecting outwardly from the trailing end of the sleeve and a sheet-material bracket surrounds this portion and has a plane aligned with a longitudinal axis of the threaded member. The bracket is formed with apertures.
