ABSTRACT:
A two piece fastener includes a pin member having a head and a shank portion having a plurality of grooves thereon, as well as a tubular membered swaged into locking engagement with a predetermined number of the grooves by means of a tool having a swaging anvil. A number of the grooves are combination locking and breakneck grooves defined by first and second radially outwardly diverging sidewalls, the juncture of the sidewalls at each of the grooves including a concave radius portion interconnecting the radially inner ends of the first and second sidewalls, a number of the grooves being located approximate the outer end of the tubular member for receiving the material of the tubular member as it is swaged. The first and second sidewalls are angulated so as to provide a relative force between the sidewalls in the selected ones of the grooves.
