ABSTRACT:
In a gas turbine engine, an annular flange of a ceramic scroll is clamped to an annular shoulder of a gas turbine engine housing by a plurality of nuts on thread rods extending perpendicular to the annular shoulder. A metal sleeve around each rod cooperates therewith in defining a coolant passage which is connected at one end to a source of compressed air and which discharges at the other end into a cooling chamber around the nuts through grooves in a surface of each nut. Air circulating in the coolant passages and through the cooling chamber cools and thermally shields the rods and the nuts.
