There are more strict requirements for load-bearing assemblies. However, the screws must penetrate through both framing members a minimum of three full threads. The subsequent installation (screw attachment) of the gypsum panel is more than sufficient to hold the metal stud in a final desired position for non-structural conditions with regard to interior partitions. Cold-formed steel framing manufacturers hem or toe–in track legs to provide a friction fit. The primary purpose of the screw attachment is to hold the stud in place and prevent inadvertent movement of the stud by other trades on site. In non-fire rated, non-shear value and non-load bearing partitions, it is allowable by ICC Evaluation Reports and per industry recommendations to friction-fit a metal stud into a metal track and attach a single side of the stud to track at the top and again at the base of the partition.
