TAMPER RESISTANT HINGE PIN RETENTION

摘要

A pin can be retained in a hinge or other set of work pieces 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 work pieces. 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 work pieces in a way that provides for the work pieces to pivot around the pin.
