Abstract
A fastener and a fastener system using the fastener are disclosed. The fastener has an elongated shank having a thread formed at one end and a annular recess formed adjacent the threaded portion to define a leading and trailing abutment surface. The thread guides the fastener into engagement with one or more components having thread engagement features and the annular recess permits the free spinning of the fastener without further tightening after the thread engagement features have advanced past the thread. The fastening system includes the fastener and a component to be fastened having a passageway for accepting the fastener formed by at least two flanges engageable in the thread and engageable in the annular recess of the fastener.
