Abstract
A generally trumpet-shaped fastener includes a generally circular flange portion flared outwardly from an elongated pin portion. The fastener is hollow and open at the flange portion and the opposite end of the pin portion, thus allowing air to escape during securement of the fastener to an attachment member that is to be held in place on a base member by the fastener. In addition, a number of discrete ridges or other protuberances are formed on the outer side of the flange portion in order to enhance the engagement and securement of the flange portion of the fastener to the underside of an attachment member, either by integrally molding or by ultrasonic welding.
