What is a keyed screw jack?

Some loads do not prevent lifting screw rotation-these applications require a keyed jack. A key, fixed to the jack housing and inserted into a keyway milled into the lifting screw, forces the lifting screw to translate without rotating. Several dimensions of keyed jacks differ from normal jacks-check the keyed jack drawings for each jack model.You can view a keyed jack on the Jack Designs page.
