Abstract
A self-clinching fastener suitable for connection to a member having a shank of a diameter less than a head portion, the head portion having at least eight lands extending outwardly along the underside of the head portion spaced about the shank, each land having a face surface extending beyond the shank to a diameter less than or equal to the radius of the head portion, the width of the lands reducing from adjacent the shank toward the radius of the head portion. The fastener further includes an axial annular engagement groove having a diameter larger than the shank, the annular engagement groove axially extending from the lands to a retaining collar adjacent the shank, the groove adapted to relieve material of a member on installation by receiving material as the lands in the underside of the head portion mechanically interlock with the member.
