ABSTRACT:
A system for inserting and retaining a fastener between two generally parallel spaced apart webs formed on a first workpiece. The fastener is inserted using ultrasonic energy to deform the material of the webs to engage an axial force resisting portion and a torsional force resisting portion of the fastener with the material of the webs. The present invention includes the fastener which is constructed for use in the system, as well as an article employing the fastener for attaching the first workpiece, to which the fastener is attached, to a second workpiece.
