6HW-5438 HEAT-UP/COOL-DOWN BIMETAL TIMER FOR ELECTRIC TOASTER ABSTRACT OF THE DISCLOSURE A heat-up/cool-down bimetal timer for an electric toaster wherein a unique screw fastener is provided for holding a calibration adjustment screw without being deformed during automated adjustment of the screw. The fastener is made from a blade of spring sheet metal that has an end turned on itself in the form of a cylinder for holding the calibration screw. Thus, the axis of the screw is parallel to or even in line with a plane that lies midway between the planes of the major surfaces of the sheet metal fastener. Accordingly, any automated screw driving equipment that may push downwardly on the head of the screw for adjusting it normally would not flex or bend the fastener in a plane perpendicular to one of its major flat surfaces.
