Abstract: A screw bolt for connecting a lower casing part of a turbine and an upper casing part of a turbine, has a bolt body with a lower end and an upper end, an external thread being arranged on both the lower end and the upper end. A casing for a turbine has a lower casing part, an upper casing part, a screw bolt and two attachment nuts screwed onto ends of the screw bolt, wherein the upper casing part has an upper receiving section and the lower casing part has a lower receiving section of a continuous screw bolt receiving portion for receiving the screw bolt. A turbine has such a casing and a method for assembling such a casing of a turbine.
