Embodiments of the present invention provide a fastening support assembly configured to securely connect a first panel above a second panel. The fastening support assembly includes a shaft having a cap at a first end and a distal tip at a second end. The shaft defines an internal chamber. The distal tip is configured to secure to the first panel. A pin is positioned within the internal chamber, wherein movement of the pin into the internal chamber radially expands the shaft. A portion of the shaft and the pin proximate the cap are configured to substantially fill a hole formed through the second panel when the second panel is secured to the fastening support assembly.
