CR-05Drill and fit the right fixing for your wallFor a metal stud: never use a plain wall plug or an ordinary wood screw, both strip straight through 0.5mm steel. Drill a small pilot hole and use a self-drilling metal-stud screw where you've hit a stud, or a spring toggle/hollow-wall anchor rated for the load if you're fixing into the plasterboard between studs. For timber studs, drill a 2mm pilot hole into the centre of the stud and drive a 40mm wood screw straight in, no plug needed. For solid brick or block, drill a 6mm hole to the plug's depth and fit a plug before screwing. For dot-and-dab, check the void behind the board first (usually 30-50mm) and use a fixing long enough to bite into the masonry behind, not just the plasterboard. For lath and plaster, drill slowly through the plaster and lath into the timber behind — it crumbles easily, so go steady and expect to patch small chips afterwards.
