Abstract

A member formed of ceramic refractory material has therein an opening. A metal coupling member for attaching a metal member such as a rod or a tube, to the refractory member has an externally threaded portion extending into the opening in the refractory member. The coupling member has a head extending radially outwardly beyond the threads of the threaded portion and embedded in the refractory member. The opening in the refractory member may be internally threaded to receive the threads of the threaded portion of the coupling member.
