Abstract
A fastener having a head and a cylindrical shank, the shank having a first set of opposed wings extending from two opposed longitudinally extending segments and a second set of opposed wings extending from the two other opposed longitudinally extending segments. Wings in opposing segments are identical. Wings in the first set have a larger radial diameter than wings in the second set. Wings in adjacent segments are offset a distance longitudinally. There is a longitudinally extending spacing between one radial edge of each wing in the first set and one radial edge of each wing in the second set. Each of the wings in the second set has a flattened portion on a distal edge that extends to a radial edge. The fastener is particularly useful for maintaining a high ratio of disengage force to engage force over a range of aperture sizes, shapes, and panel thicknesses.
