Double Clevis Screw Jack incorporates a special clevis end bottom pipe and a standard clevis end on the lifting screw. Double-clevis jacks have less load capacity than the other common mounting configurations. This tends to weaken it as a column by creating eccentric loads on the screw.

A safety nut on a screw jack is an auxiliary nut, which follows the "lifting nut" on a rotating screw jack. In normal conditions the safety nut does not support any load. The failure of the threads of the worm gear will cause the load to be transferred to the safety nut preventing the load from falling.
