DR-08Metal stud: fit a noggin first, then use the right fixingNever use a plain wall plug or a wood screw in a metal stud, they strip straight through 0.5mm steel and won't hold. But a metal stud on its own also won't hold a drying rack, because the arms pull away from the wall as you load wet washing onto them. Cut a small access hole in the plasterboard, screw a timber noggin (roughly 800mm long, 44x22mm) horizontally between the two nearest studs using self-drilling metal stud screws, then patch the hole and fix the rack's screws into the noggin once the patch is dry. If you'd rather not cut into the wall, fix through to the masonry behind instead, or choose a different wall for this job.
