An axial screw operably connected to a crank at the top of the jack extends through the tubes for altering the length of the jack.

In order to reduce the material volume of the screw nut, the nut is positionally captured within a retainer seated within the lower tube The retainer is configured to seat within the upper end of the lower tube and includes a slot for receiving the screw nut. The nut and the retainer include corresponding flats to prevent rotation of the nut within the retainer.
