  • TAMPER RESITANT HINGE PIN RETENTION
    Publication number: 20160130850
    Abstract: A pin can be retained in a hinge or other set of workpieces by a ferrule crimped onto an annular notch near the terminus of the pin. The ferrule can have a flange that acts as a stop preventing the pin from being removed from the workpieces. With appropriate length of the ferrule and location of the notch, a particular desired degree of play can be introduced. One use of this fastener assembly can be to join two or more workpieces in a way that provides for the workpieces to pivot around the pin.
