ABSTRACT:
The present invention is in the field of anchor bolt assemblies which are used as wall or ceiling mounts. The present invention includes a shaft with opposite first and second ends formed as a body and a neck joined at a shoulder. The body has a cross-section that is sized for close fitting insertion in the wall or ceiling. The neck extends longitudinally of the body to terminate in a second end. The neck cross-section is formed to have a longitudinal recess. The device also includes engagement means on the shaft for engaging a mounting element. A cross-piece having first and second arms is attached by hinge means to the shaft. The cross-piece is sized to fit within the longitudinal recess when the device is installed in the wall. Upon installation, the cross-piece snaps out of the recess and braces against the back of the wall or ceiling. The shaft maybe threaded or ratcheted.
