A retainer assembly for retaining a fastener that includes a shank having a recessed portion therein is disclosed. The retainer assembly includes an inner wall that is inset from and outer wall and is symmetrically positioned about an axis defining a chamber through the retainer body. The chamber includes opposed entrance and exit apertures. The inside wall includes a first inside diameter that extends from the entrance aperture in a direction along the axis and narrowing to a second inside diameter at a slip-over profile, and the inner wall narrowing again to a third inside diameter at an annular ring that extends to the exit aperture. The fastener is inserted through the entrance aperture until the shank engages and then slips over the slip-over profile and through the annular ring so that the recessed portion of the shank is captured within the annular ring.
