A self-anchoring fastening device for installation in supports for hanging pipes wires or other articles in ceilings is shaped for a socket to drive the device for an easy installation process. The device comprises a collapsible anchoring portion having radially expanding anchoring strips, which will not pull out of a hole drilled in a support. A drill drills a hole in a support and an expandable anchor is inserted through the hole. Threads internal to the expandable anchor cooperate with threads on a screw inserted therein to collapse the expandable anchor, providing anchoring strips over the hole such that the expandable anchor cannot be pulled out of the hole. A threaded portion of the base of the screw is suitable for attaching the article to be hung. The base may be a swivel head type. The drill may be on the expendable anchor assembly.

Mushrooming expandable anchor

The installation tool for a mushrooming expandable anchor has a hollow cylindrical sleeve with an inside diameter, the top having slots for engaging the base of the mushrooming component and a means for engaging and turning a threaded component, which compresses the mushrooming component. The means for turning the threaded component can be a socket, which rotates inside of the sleeve and engages a hex head at the base of the threaded component or alternatively the means for turning the threaded component can be a threaded rod for threading into the base of the threaded component until it reaches the end of the threads in the base. Another means of turning the threaded component is a screwdriver engaging a slot in the treaded component. All of the means for turning the treaded component may be by a powered drill with a connective adapter.
