Compact fastening collar and stud for connecting walls of a nozzle liner and method associated therewith

A combination for connecting a hot sheet and a cold sheet of a nozzle liner in spaced relationship apart, comprising:

• a stud having a main body wherein the stud is attached to the hot sheet, said stud having a face in contact with said hot sheet, and over a solid surface of said hot sheet such that said stud does not extend through a hole in said hot sheet to an opposed side of said hot sheet, and portion of the stud extends through an opening in the cold sheet;
• a support spacing the hot sheet and the cold sheet apart;
• a generally planar fastening collar affixed to a portion of the stud extending through the cold sheet;
• a first length defined by the portion of the stud extending through the cold sheet to a distal end of the stud;
• and
• a second length defined between a first planar surface of the collar facing the cold sheet and a second planar surface of the collar opposite the first surface;
• a distance defined between the hot sheet and the cold sheet;
• wherein each of the first and second lengths is less than the distance between the cold sheet and the hot sheet.

A method of connecting a hot sheet and a cold sheet of a nozzle liner in spaced relationship apart, the method comprising the steps of:

• providing a stud affixed to the hot sheet, said stud having a face in facial contact with said hot sheet, and not extending through a hole in the hot sheet to an opposed side of the hot sheet;
• disposing a portion of the stud through an opening in the cold sheet wherein the portion defines a first length from the cold sheet to a distal end of the stud;
• providing a generally planar fastening collar having a bore;
• placing a first surface of the collar toward the cold sheet such that the portion extends into the bore wherein the collar includes a second surface opposite the first surface and wherein the first and second surfaces define a second length therebetween;
• and
• permanently affixing the collar to the stud;
• wherein each of the first and second lengths is less than a diameter of the main body of the stud.
