Abstract
An apparatus includes structure defining a first hole that is characterized by an opening. A protuberance surrounds the opening and at least partially defines a concavity. A retention member is disposed within the concavity, and defines a second hole. The second hole has a first portion characterized by a first diameter and a second portion characterized by a second diameter. A threaded fastener has a flange characterized by a third diameter greater than the first diameter and less than the second diameter. The flange is disposed within the second portion of the second hole and between the first portion of the retention member hole and the first surface. Accordingly, the retention member retains the fastener in the concavity while permitting radial movement of the fastener.
