Abstract: A unitary, non-metallic captive panel screw adapted to be inserted in a suitable orifice defined in a workpiece includes a head and an outwardly projecting, multi-section shaft. A shaft spacer section has a diameter less than the diameter of the head, and extends a predetermined length from the head, terminating in a spaced-apart shoulder portion. A relief section of the shaft extends axially outwardly from the spacer section, and is substantially smaller both in diameter and length than the spacer section. A terminal threaded section having a diameter smaller than either the relief section or the spacer section is adapted to threadably receive a suitable nut whereby to secure a mechanical component in spaced relation relative to a workpiece. An integral generally frustro conical snap-fit flange section divides the terminal threaded section from the relief section, and includes a plurality of radially spaced-apart wedge shaped members extending radially outwardly from the axis of the screw.
