Abstract: A fastener for mounting a panel to a supporting structure includes a fastener part having a base with an upper and lower side. A connector is adapted to engage with another fastener part projecting from the upper side of the base. The lower side of the base is adapted to be adhesively connected to a substrate and incorporating a surface configuration that promotes a mechanical connection with an adhesive. The lower side surface configuration includes a protrusion extending from the base to a crown. The protrusion includes an undercut portion configured to form a mechanical connection with the adhesive. In use adhesive fills between the protrusions and forms a mechanical connection with the undercut portions when hardened.

Abstract: A method of installing panels includes temporarily securing un-upholstered panels in place on an underlying support and marking the underlying support at each of a plurality of panel clip locations on the panel. The panel is removed from the support structure for upholstering. The support structure is drilled at the marks to provide a hole to receive a socket component, and a socket component is driven into each of the receiving holes in the support structure. The socket component includes a cup open to at least one end, an external thread for engaging the support structure, and a constriction in the cup spaced away from the bottom of the cup. A plug component is secured at each of the panel clip locations on the panel, the plug component having a protruding portion to engage in the socket. The upholstered panel is lifted into position and the periphery is pressed into place to engage the protruding portions of the plug components within the cups of the sockets.
