ABSTRACT:
A fastener assembly for securing a first panel member to a second panel member in a spaced-apart relationship. The fastener comprises a tubular shank portion having first and second end portions, a cavity being formed in the shank portion. A first spring member is secured on the outside of the shank portion and has openings near the first end of the shank portion to enable steel ball members to protrude therefrom. Inside the shank portion cavity is a stepped pin member that is spring loaded and held in place by a combination of the shank portion spring ball retention feature and step angles formed on the pin member. A tubular shaped member is positioned adjacent the exterior surface of the ball members to ensure that the ball members do not extract themselves from their position within the cavity in case vibrations exceed time and frequency specifications.
