Abstract

A blind rivet assembly with a tubular rivet body having a flange at one end and a mandrel which projects from the rivet flange and can be pulled to set the rivet at its tail end. The mandrel has heads at both ends, one to set the rivet and the other to engage pulling means of the setting tool. The setting and pulling heads of the mandrel are rounded. The mandrel has a neck within the rivet at which it breaks when the rivet has been set. The invention enables a shorter mandrel to be used, and facilitates its economical manufacture without adversely influencing the characteristics of the breakneck. The invention also facilitates feeding of the assemblies automatically to rivet setting tools.
