CP-06Drill and fix — the right fixing for your wallSolid brick or block: drill a 6mm hole 40mm deep, insert a plastic wall plug, then drive in a screw. Plasterboard on timber studs: pilot with a 2mm bit and drive a wood screw straight into the centre of the stud, no plug needed. Plasterboard on metal studs: never use a plastic plug or a wood screw, which strips straight through 0.5mm steel — use a self-drilling metal-stud fixing where the bracket lands on the stud, or a toggle-type hollow-wall anchor rated for the pole's weight where it falls between studs. Dot-and-dab plasterboard: use a fixing long enough to pass through the dab void and bite into the masonry behind, typically 60-75mm. Lath and plaster: fix into the timber studs or joists behind the laths, not the plaster alone, using a pilot hole to stop old plaster cracking.
