Abstract
A drive head for the screw of a scissors jack which is formed in the shape of a wing nut which has a hexagonal socket formed between opposed walls so that a conventional folding lug wrench can be used by inserting its hex tube into the hexagonal socket to drive it. In the event of overload, the lug wrench will slip relative to the wing nut so as to prevent excessive loads and stresses upon the jack.
