a body comprising a threaded bore that terminates at a flange adjacent a front annular face of the body,
the threaded bore defining a tightening direction and a loosening direction opposite the tightening direction; and
a plurality of wings,
a wing, of the plurality of wings, comprising:
a forward facing side face that is configured for engagement of the forward facing side face to produce a torque in the tightening direction to install the wing nut, and
a reverse facing side face that is configured for engagement of the reverse facing side face to produce a torque in the loosening direction to remove the wing nut,
the forward facing side face being disposed at an angle relative to a lug centerline of the wing,
the reverse facing side face being disposed at an angle equal to the angle relative to the lug centerline,
the lug centerline extending parallel to, but at an offset distance from, a corresponding radius that extends from the wing to a center point of the threaded bore, and
