A combination for connecting a hot sheet and a cold sheet of a nozzle liner in spaced relationship apart includes a stud having a main body wherein the stud is attached to the hot sheet and a portion of the stud extends through an opening in the cold sheet. A support spaces the hot sheet and the cold sheet apart. A generally planar fastening collar is affixed to the portion of the stud extending through the cold sheet. A first length is defined by the portion of the stud extending through the cold sheet to a distal end of the stud. A second length is 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. Each of the first and second lengths is less is less than a diameter of the main body of the stud.

The invention claimed is: 1. 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 surfac
The invention claimed is: 1. 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 a 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 the 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; wherein each of the first and second lengths is less is less than a diameter of the main body of the stud. 2. The combination of claim 1, wherein the support is a shoulder flange extending from the main body of the stud. 3. The combination of claim 1, wherein each of the first and second lengths is less than one half of the diameter of the main body. 4. The combination of claim 1, wherein each of the first and second lengths is less than one third of the diameter of the main body. 5. The combination of claim 1, wherein each of the first and second lengths is less than one-fifth of the diameter of the main body. 6. The combination of claim 1, wherein each of the first and second lengths is less than a distance between the hot sheet and the cold sheet. 7. The combination of claim 1, wherein the support is a shoulder flange extending from the main body of the stud and wherein the collar and the shoulder flange capture the cold sheet therebetween. 8. The combination of claim 1, further comprising a washer disposed between the shoulder flange and the cold sheet. 9. The combination of claim 1, wherein the planar collar includes a bore surrounding the portion of the stud extending through the cold sheet and wherein the bore includes a thread. 10. The combination of claim 9, wherein the thread has a circumferential extent less than a circumference of the bore. 11. The combination of claim 1, wherein the collar is welded to the stud. 12. The combination of claim 1, further comprising a hanger bracket fastened between the cold sheet and the collar. 13. The combination of claim 1, wherein the collar comprises a first collar, the combination further comprising a second collar also fastened to the stud and wherein only one of the collars is welded to the stud. 14. The combination of claim 1, wherein the opening is sized sufficiently larger than the diameter of the stud to allow relative longitudinal movement of the hot sheet relative to the cold sheet. 15. 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. 16. The combination of claim 15, wherein each of the lengths is less than one half of the distance between the sheets. 17. The combination of claim 15, wherein each of the dimensions is less than one third of the distance between the sheets. 18. The combination of claim 15, wherein each of the lengths is les than one-fifth of the distance between the sheets. 19. The combination of claim 15, wherein each of the first and second lengths is less than a diameter of the main body of the stud. 20. The combination of claim 15, further comprising a washer disposed between the shoulder flange and the cold sheet. 21. The combination of claim 15, wherein the collar is welded to the stud. 22. 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. 23. The combination of claim 22, wherein each of the first and second lengths is less than one half of the diameter of the main body. 24. The combination of claim 22, wherein each of the first and second lengths is less than one third of the diameter of the main body. 25. The method of claim 22, wherein each of the lengths is less than a diameter of a distance defined between the sheets. 26. The method of claim 22, wherein the bore includes a thread and the affixing step includes threading the bore onto the stud. 27. The method of claim 22, wherein the bore includes a thread having a circumferential extent less than a circumference of the bore. 28. The method of claim 27, wherein the affixing step includes welding the collar to the stud. 29. The method of claim 22, wherein the collar comprises a first collar, the method further comprising the step of placing a second collar, identical to the first collar onto the stud. 30. The method of claim 22, wherein the affixing step includes welding the collar to the stud. 31. The method of claim 26, wherein the collar has a non-cylindrical outer periphery to provide wrench flats. 32. The combination of claim 15, wherein said collar has a bore that is threaded onto said portion of the stud. 33. The combination of claim 32, wherein said collar has a non-cylindrical outer peripheral surface to provide wrench flats. 34. The combination of claim 9, wherein said planar collar has a non-cylindrical outer peripheral surface to provide wrench flats.
