Abstract
A fastener retention system, including for a filter housing, applies an axial retention force in a plastic molded structure having a bore in a standing tower extending along an axis. A fastener extends axially in the bore and has a first axial end retained in the bore in snap fit relation, and a second distally opposite axial end extending axially beyond the bore for mating with a retaining member holding a cover on a base in a filter application in assembled condition. The fastener is secured to the tower in permanent snap fit relation. The fastener is axially slid into the bore before crystallization and hardening of the plastic. The fastener is axially trapped in the bore between spaced facing abutments, and is anti-rotationally keyed thereto.
