Abstract
A self-retaining bolt assembly including a bolt having a head, a shank, and a threaded end adapted to be inserted into a hole in a panel or the like for subsequent coupling to a nut on the blind side of a subpanel. The bolt includes a detent engaging one side of the panel in which the bolt is inserted with the head thereof on the opposite side of the panel. The hole for the detent is placed in the location on the bolt that allows maximum strength capability through both the grip area and through the thread area of the bolt. This is accomplished by the use of a locking element of detent that does not require a hole in the shear or threaded area of the bolt. A nut can then be threaded to the end of the bolt projecting through the panels.
