Abstract
Predetermined limits are attained for the peak loads encountered when a composite assembly of workpieces is secured with a swaged collar fastener, by disposing cavities in the cylindrical wall of the fastener collar to receive material flow during the swaging operation. Rotation between the collar and pin of the fastener is precluded by disposing abutting portions on the pin, which interface against the swaged material of the collar. Fastener cost reductions are achieved by decreasing the volume of a post-swage scrap portion on the pin and by concurrently fabricating grooves thereon with a rolling die, for various functional purposes. Swaging tool malfunction is avoided by eliminating land surfaces adjacent to grooves on the pin through which pull is applied thereto with the tool.
