A system for supporting bolted upper and lower diaphragms to one another in an outer housing of a turbine includes support screws threaded into bores adjacent opposite sides of the lower shell. The head of each support screw has a threaded bore receiving a set screw. The set screw has a length equal to the depth of the slot in which the head resides in the lower shell, minus a small clearance. With the diaphragms supported by the engagement of the set screw at the lower end with an abutment at the bottom of the slot, the clearance enables the diaphragms to move vertically upwardly, limited by the clearance distance.
