A fastener has provided particularly useful for mounting a panel to an underlying supporting structure. The fastener includes a socket component and a plug component. The socket component has a cup open at one end and an external spiral thread. The axis of the spiral thread is parallel with the open direction of the cup. The socket may be embedded in a predrilled aperture in a supporting structure by a rotary driving action. The wall of the cup provides a constriction or throat spaced from the bottom of the cup. The plug component has a base with an external spiral thread and a protrusion from the base. The base of the plug can be screwed into a predrilled aperture in a panel. A protrusion from the base extends substantially co-axial with the axis of the thread. The protrusion includes a head portion spaced away from the base. The protrusion is sized to enter the cup of the socket component and the head portion is sized to interfere with the throat but to be forcible past the throat. With the head of the plug component forced past the throat of the cup the plug component is engaged in the socket. The fastener provides a panel mounting solution that is easy to install and where the components can be replaced as required. |
