Abstract
An improved fastener comprising a fastener body having a tool-engaging portion, a threaded fastening portion and a shroud-receiving body portion; a shroud concentrically mounted on the shroud-receiving body portion and having an inner surface facing an outer surface of the shroud-receiving body portion; the inner surface of the shroud comprising an annular groove and the shroud-receiving body portion comprising a substantially arch-shaped axially-buckled radially-extending annular protrusion extending outwardly transverse to the central axis and disposed in the annular groove of the shroud; and the annular protrusion and annular groove of the shroud forming a shroud-retaining element restraining the shroud from movement in at least a first axial direction along the central axis such that the shroud will rotate relative to the fastener body under an applied external torque prior to the fastener body rotating when the fastener is engaged with an external structure at a design installation torque.
