• a second tubular member, the second tubular member including a threaded box section configured to mate with the threaded pin section;
• and
• a shoulder ring disposed between the first tubular member and the second tubular member, wherein a wall thickness of at least a portion of the shoulder ring is greater than the smallest wall thickness of the threaded pin section of the first tubular member.
