FLAT HEAD SLEEVE ANCHORS
A device consisting of (1) a threaded stud with a conical end flared outward, (2) a hollow,       
cylindrical dilating sleeve assembled over the stud and positioned against the minor diameter of    
the cone, and (3) a countersunk flat head at the end opposite the cone.  The anchor works by
expanding against the material in which it is embedded.  When the flat head is turned clockwise,
the conical end is pulled into the dilating sleeve, pushing it outward 360° around the anchor
into the masonry.
