ABSTRACT:
A fastener assembly having a bolt having a shaft and a nose portion at its terminal end. A ring is mounted on the bolt. The ring is an elongated piece of resilient material curving from a first end about the bolt shaft, then curving back around to a second end adjacent the first end parallel thereto but spaced therefrom. In this manner the ring resiliently grips the bolt shaft and is adapted to hold the bolt in a hold out position when it is mounted in aligned openings in abutting panels.
