Abstract
An optimized two piece fastener system and a related method for providing an optimized fastening system including a pin member and a collar having an optimized strength to weight ratio with the materials of the pin member and collar having a predetermined tensile strength ratio, the collar having a preselected excess volume to provide a desired `overpacking` condition, the collar being of size whereby after swage it will define a minimum wall thickness whereby failure can incipiently occur in shear and/or compression and with a pull type fastener providing a breakneck groove with a preselected stress concentration factor whereby the fastener system can be set on workpieces having a collar engaging surface from 0.degree. to 7.degree. relative to a plane normal to the pin axis.
