Abstract

A self-clinching fastener for attachment to a plastically deformable metal panel includes a body portion with a central axis and a central pilot or punch portion extending from the body portion and coaxial with the central axis. The fastener includes a plurality of spaced apart lugs encircling the central pilot portion and axially extending from at least one of the end face and the groove. The lugs form abutments to improve torsional resistance of the fastener.
