ABSTRACT:
A unique two-part fastener consisting of a pin and a tubular member in which the pin has substantially identical annular grooves formed along a major portion thereof and in which the annular grooves provide combination grooves some of which functions as locking grooves, a selected one which functions as a breakneck groove and others which can function as the pull grooves with a unique relationship between the grooves and a swaged portion of the tubular member so that as the fastener is set, the pin will break off in a preselected one of the combination grooves within the outer end of the tubular member.
