Circuit board fasteners and their assembly

A fastening assembly consisting of two interconnected elements for joining electronic components, compromising:

• a fastener stud with a planar base at the bottom and an upwardly extending shank with a neck portion of reduced diameter adjacent the base, the shank having a spherical ball portion with a flat planar top at a distal top end of the fastener stud;
• a retainer with a planar base and having affixed opposing resilient arms extending orthogonally from the base centered about a rotational axis, said arms having compound shaped inner surfaces symmetrical about the axis consisting of a cylindrical portion adjacent the base and a spherical portion adjacent the distal ends of the arms;
• wherein the retainer arms and fastener stud are joined by non-destructive releaseable snap-fit;
• and
• wherein an inner surface of the retainer base is flat and in face-to-face abutment with the fastener stud flat planar top.
