Abstract
A fastening device including an elongated nut provided with a central screw threaded opening, a flexible line including a small disc formed on an inner end thereof, a finger grip portion on an outer end and a pre-centering intermediate portion including a central pin for engagement through a hole in the central span portion of a cover strip for the outside surfaces of a pair of double-sided pressure highly sensitive adhesive foam tape portions secured to opposed end portions of the nut. A resilient centering member is engaged in the screw threaded nut opening with a tail portion of the flexible line passing therethrough, whereby the nut in assembly on the tail portion of the line may be inserted completely through a properly sized hole in a wall plate or sheet material, for example, and a single pull administered by one finger inserted through the finger grip portion will remove the cover strip from the double-sided foam tape, resulting in the nut being secured to a blind inside wall plate or sheet material by means of the foam tape, and the complete removal of the flexible line, cover strip and centering member.
