ABSTRACT:
The fastening element uses a sleeve with a flanged end to insert in a hole drilled through an object, such as, a sign, and a structural element to which the object is to be attached. This allows the user to place the object in the position to be mounted and to drill a single hole of uniform diameter and insert the sleeve. An expandable element which either uses a plurality of bendable legs, or a pair of toggle elements, similar to a Toggle Bolt, is inserted with the sleeve to provide anchor members behind the structural element, such as a wall. The fastening element essentially allows one step drilling of a hole and securing of an object to a structure particularly in instance where access for use of a fastening nut on a bolt is not possible. The head of the bolt is of a sufficient radius to cover the flanged end of the sleeve when the fastening element is secured. The toggle element may also be used without the sleeve.
