Description
A device for giving stability to one part of a structure by making it fast to another consisting of (A) a threaded stud with a conical end flared outward; (B) a hollow, cylindrical dilating sleeve assembled over the stud and positioned against the minor diameter of the cone; (C) a washer and low-crown cap nut assembled at the end opposite the cone

Applications/ Advantages
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

They are designed to be used in solid or hollow masonry, including cinder block, brick, marble and concrete

One advantage of the sleeve anchor is that it can be removed after it's been installed

Another is that the length of the sleeve induces less stress on the substrate than does a wedge anchor

The acorn nut variety is preferred when a decorative finished look is desired (ie. attaching theater seating to the floor)
