ABSTRACT:
A swage type fastener including a swageable collar member having a pintail member secured thereto to define a pintailed collar; the pintailed collar is operable to be secured to a stud or pin member by an installation tool which applies a relative axial force between the pintail member and collar member to cause a swage anvil to swage the collar member into a locking groove portion on the pintail member and then to sever the pintailed member from the installed collar member; the stud or pin member can have a gripping groove construction at its free end to grip the collar member at initial swage and relatively low swage loads and to resist the installation tool pulling the collar member into the swage anvil instead of swaging it onto the stud or pin member under the subsequently high swage loads.
