Abstract
A jacking screw for attaching a first panel to a second panel which provides a force in the axial direction of the screw when the screw rotates in a first direction to jack the first panel down to the second panel and which provides a force in the axial direction of the screw with respect to the panel when the screw is rotated in the opposite direction to pry the first panel away from the second panel. The jacking screw has a screw, a ferrule surrounding and coaxial to the screw shaft, and a knob. The first end of the ferrule is attachable to a panel and the second end has an outwardly protruding annular step. The knob is attached to the head of the screw and Ahas a downwardly extending generally cylindrical portion, coaxial to the screw shaft and the ferrule and the downwardly extending cylindrical portion secures the knob to the ferrule allowing for rotational movement of the knob with respect to the ferrule but allowing substantially no axial movement of the knob with respect to the ferrule.
