• the stud bridge member, and the at least a first stud;
• the stud bridge member comprising:
• a web (200) having a web outer side (240), a web inner side (260), a web first edge (210) and a web second edge (220) defining a web plane (250) having a longitudinal axis (500);
• a first flange (300) and a second flange (400) extending into a space on the web inner side (260);
• and
• at least one notch set comprising a first notch (600) and a second notch (700),
• with the first flange comprising a first flange first edge (320) and a first flange second edge (340) defining a first flange plane (350) with the first flange first edge joined with the web first edge at a first juncture (510) having a first juncture outside angle (ΘM1) from the web outer side to the first flange, with a corresponding explementary inner angle (αM1), with the first juncture forming a first juncture line (520) which is substantially parallel to the longitudinal axis;
• the second flange (400) comprising a second flange first edge (420) and a second flange second edge (440) defining a second flange plane (450) with the second flange first edge joined with the web second edge at a second juncture (530) having a second juncture outside angle (ΘM2) from the web outer side to the second flange, with a corresponding explementary inner angle (αM2), with the second juncture forming a second juncture line (540) which is substantially parallel to the longitudinal axis, with either one of, or both, ΘM1 and ΘM2 having a value of greater than 270° and less than 360°;
• the first juncture line, the first flange first edge, the first flange second edge, the second juncture line, the second flange first edge, and the second flange second edge being substantially parallel with the longitudinal axis;
• the first notch comprising a first notch length (620), a first notch width (640) measured perpendicular to the first notch length, and a first notch cut plane (630) wherein the first notch length begins in the first flange at a first flange notch point (680) and extends at least through the first juncture and to a web first notch point (660);
• the second notch comprising a second notch length (720), a second notch width (740) measured perpendicular to the second notch length, and a second notch cut plane (730), wherein the second notch length begins in the second flange (400) at a second flange notch point (780) and extends through at least the second juncture to a web second notch point (760), wherein either one of, or both, the first notch length and the second notch length do not extend completely across the respective first flange and second flange;
• and
• a line passing from the web first notch point to the web second notch point is perpendicular to the longitudinal axis;
• the first stud comprising a first stud web, a first stud hole passing through the first stud web with the first stud hole having a first stud hole depth and a first stud hole length;
• wherein the bridge member passes through the first stud hole with the first notch and the second notch engaged with the first stud at the first stud hole.
