AB-05Drill and fit the right fixing for your wallTimber stud: drill a 3mm pilot hole into the centre of the stud and drive in a 50-60mm wood screw. Metal stud: use a self-drilling metal-stud fixing or a toggle-type hollow-wall anchor rated for the rack's loaded weight, never a plain wall plug or ordinary wood screw, as these strip straight through 0.5mm steel. Plasterboard between studs (timber or metal frame): use a nylon or metal toggle fixing rated for the weight, not a screw alone. Dot-and-dab plasterboard: use a fixing long enough to pass through the plasterboard, the adhesive dabs and air gap, and bite into the masonry behind, typically 75-100mm. Solid brick or block: drill with a 6mm masonry bit to 45mm depth, insert a matching wall plug, then drive in a 50mm screw. Lath and plaster: locate the timber laths with your pilot hole test, then fix into a lath or the stud behind it with a 40-50mm screw, as plaster alone will crumble.
