A push-in fastener including a head and a shank, the shank including at least one resilient fin integrally formed along its length for insertion and retention of the fastener within an aperture of an article where the fin includes at least one engagement rib formed on either side thereof for contact with the edges of the aperture and for absorbing any wear or shear caused by the edges upon insertion or removal of the fastener so the fin remains intact and maintains the originally designed insertion and retention forces.
