A fastener includes a pin member, a swage collar, and a nut. The pin member includes a shank portion having first and second ends and a threaded portion including an external thread. The swage collar has first and second ends and is adapted to be installed on the pin member and swaged onto the external thread of the pin member. The second end of the swage collar is positioned distal from the first end of the pin member when the swage collar is installed on the pin member. The nut is adapted to be installed on the pin member and has first and second ends and an internal thread adapted to engage the external thread of the pin member. When the nut is installed on the pin member, the nut is adapted to engage the swage collar such that the swage collar is retained on the pin member before swaging.

A fastener includes a pin member, a swage collar, and an insert. The pin member includes an elongated shank portion, a head, a threaded portion having an external thread and a plurality of lock grooves, and a pull portion. The swage collar includes a shank having a flange and a through bore with a first interior portion extending from a first end of the collar to a stepped portion and forming a first inner wall having a first inner diameter, and a second interior portion extending from the stepped portion to a second end of the collar and forming a second inner wall having a second inner diameter. The insert includes a through bore forming an inner wall that has an internal thread adapted to engage the external thread of the pin member.

An apparatus comprises an outer shell, a gauge ring, and a spring. The gauge ring is configured to rotate to a first position as a nut passes through an opening of the outer shell and contacts a bottom surface of the gauge ring, the first position permitting the nut to pass through the gauge ring and into a socket by aligning one or more gauge ring lobe slits with one or more outer shell lobe slits and one or more deformable lobes of the nut. The spring is configured to rotate the gauge ring to the second position after the nut passes through the gauge ring and into the socket, the second position preventing the nut from exiting the socket by preventing alignment of the one or more gauge ring lobe slits with the one or more outer shell lobe slits.

An apparatus (100) for delivering a collar (140) concentrically in line with a central axis (A) of a fastener (142) and a working axis (B) of a swager (114) is disclosed. The apparatus (100) comprises a collar feeder (102), comprising a first end (104), a second end (106), an inlet (105), an outlet (107), and a through cavity (109) in communication with the inlet (105) and the outlet (107). The apparatus (100) also comprises a contact element (112), a cam surface (116) configured to be stationary relative to the swager (114), and a slider (122) pivotally coupled to the collar feeder 102. The apparatus (100) further comprises a means for biasing (126) the slider (122) relative to the swager (114) along the working axis (B) of the swager (114), and at least one resilient flexure (128) coupled to the collar feeder (102) at the outlet (107).
