Abstract
Screw fastener engaging/disengaging apparatus suitable for attaching/detaching wheels to/from vehicles has a frame and a set of parallel spindles mounted on the frame for holding one type of screw fastener at the spindle ends. The spindle ends are arranged in a circular array with the spindles rotatable about their longitudinal axes. The screw fasteners are configured for screw engagement with screw fasteners of another type mounted on a wheel attachment member to/from which a wheel can be attached/detached. An adjustment mechanism collectively changes positions of the spindle axes between a circular array with a first radius and a circular array with a second radius.
