GH-03Choose the right fixing for your wall typeSolid brick or block: drill with a masonry bit sized to your plug, insert a wall plug, then use a screw long enough to bite 30-40mm into the masonry. Plasterboard on timber studs: aim for the centre of a stud and use a 40mm wood screw straight in, no plug needed. Plasterboard on metal studs: never use a plastic plug or an ordinary wood screw, it strips straight through 0.5mm steel — use a self-tapping metal-stud screw if you land on the stud, or a metal toggle/hollow-wall anchor rated for the load if you land between studs. Dot-and-dab plasterboard: you need a long fixing (typically 50-75mm) that passes through the void and bites into the masonry behind, not just a standard plasterboard plug. Lath and plaster: avoid the laths themselves where possible and use a proper plasterboard-style toggle fixing rated for the wall's condition, as old plaster is often crumbly.
