ABSTRACT:
A flush mounted panel fastener is provided for use in aircraft or the like of the so-called stealth type designed to avoid detection by radar. The panel fastener comprises a fastener element such as a threaded bolt having a head and shank for fastening a panel onto a substrate or frame. The head is sized for recessed seating within a counterbore formed in the panel, and a fastener cap is mounted and magnetically retained on the head of the fastener element. The fastener cap has a surface coating or finish thereon disposed substantially coplanar with an outer surface of the panel, wherein the surface coating is formed from a suitable nonreflective radar material and cooperates with the panel to present a substantially uninterrupted surface of low radar signature.
