Abstract
A fastening device such as a rivet collar that includes a retention element is disclosed. The retention element enhances the retention of a fastener within the fastening device by frictionally engaging the fastener. The retention element comprises a heat resistant base polymer, such as a reactive hot melt, an ethylene acrylic acid copolymer, or a polyethylene polymer blend, that does not melt or become tacky even at high temperatures, and therefore has high stability even under extreme storage conditions. Also disclosed is a method of forming such retention element on a fastening device.
