A hybrid wheel hub for trucks is configured to accept interchangeably a threaded screw-on hubcap or a bolt-on hubcap. The hybrid wheel hub comprises a barrel with an axial bore for receiving an axle along a longitudinal axis of the axial bore and a radial flange for attaching a wheel, the barrel having an inboard end and an outboard end including an outboard bearing cup for retaining an outboard bearing assembly within an inner surface of the axial bore. An annular perimeter of the outboard end includes a plurality of bolt holes positioned to receive cap bolts to retain a bolt-on hub cap over the outboard end. A threaded track protrudes radially inward towards the longitudinal axis of the axial bore and is internally threaded circumferentially around the longitudinal axis in position longitudinally to receive a screw-on hub cap having external threads.
