ABSTRACT:
A retaining apparatus disposable within an axial bore for maintaining a fastener having an extending shank within a bore provided on a structural member. In the preferred embodiment, the retainer comprises a convoluted, polymeric, thin-walled annular body constructed of a resilient material with an aperture extending therethrough. The unitary body is defined by longitudinally extending radially outwardly projecting ear portions and radially inwardly projecting ribs which circumferentially alternate in a symmetrical pattern. A method for pre-attaching fasteners to structural members includes disposing the retainer within a bore contained on a structural member and subsequently inserting the fastener through the retainer's aperture. The fastener is thereby flexibly maintained along the central axis of the bore. The structural member may then be transported with fasteners pre-attached for subsequent attachment to another structural member. The fasteners may be shifted and/or tilted, as necessary, within the first bores in order to align the fastener shanks with the corresponding bores contained on the second structural member which may or may not be in axial alignment with the bores of the first structural member.
