Abstract
A swage type fastener including a pin and a collar adapted to be swaged onto the pin by the application of a relative axial force by an installaiton tool, with the pin having a lockgroove portion, a tubular collar having an inner and outer end and adapted to be located on the pin and having a collar shank portion adapted to be swaged into the lock groove portion by the relative axial force applied between the pin and the outer end of the collar by the installation tool, the collar having a through bore which has a reduced diameter bore portion whereby the collar is generally piloted on the pin, and the collar shank portion being generally frusto conically shaped from the reduced diameter bore portion to an enlarged bore portion at the outer end, the collar shank portion having a generally uniform wall thickness from the outer end for a distance over its swageable length whereby the frusto conical shape of the collar shank portion provides a high hold-off to resist initiation of swage of the outer end of the collar into the locking grooves of the pin and whereby the generally uniform wall thickness provides for a generally uniform fill of the lock groove portion substantially without distortion.
