A screwing control device of a computer chassis is composed of a computer chassis, a panel of which is pre-built with a plurality of positioning holes; a screw element, a center of which is provided with a screw hole and which is able to be locked and fixed into one of the positioning holes; and a bolt, which is transfixed into a through-hole of a board element, and is then screwed into the screw hole of the screw element. Therefore, a quantity of the screw elements which are actually used for screwing can be effectively controlled, and pre-built projected bolts which are not necessarily used for screwing can be eliminated.
