ABSTRACT:
A fastener has a head portion with a torque accepting surface and a cylindrical recess on an external surface thereof defining a pair of axially spaced annular shoulders for acceptance in a circular fastener accepting aperture in a connector component. The aperture has a counterbore for the acceptance and seating of the head portion of the fastener and a channel extending radially of a longitudinal axis of the aperture therein for the acceptance of the fastener in translation, the channel having parallel shoulders spaced slightly greater than the diameter of the cylindrical recess in the head portion of the fastener but less than the minimum diameter of at least one of the shoulders thereon.
