There is disclosed a liner element in the form of an impingement/effusion tile for a gas turbine combustor having a structural wall. The liner element has a unitary construction defining a cooling side and combustion side, and a plurality of effusion holes extending between a cooling side surface of the element and a combustion side surface of the element. The liner element is configured to be affixed to the structural wall of a combustor with its cooling side surface spaced from the structural wall to define a chamber between the cooling side surface and the structural wall, and the liner element further includes integrally formed and internally threaded protuberances on its cooling side, the protuberances being arranged to engage the structural wall.
