MH-04Drill and fit the right fixing for your wallSolid brick or block: drill 6mm at 90° to a depth of 35-40mm, push in a matching wall plug, then drive a 40mm screw in leaving a few mm protruding for the hook. Dot-and-dab plasterboard: the board sits on adhesive dabs with an air gap behind, so a plug in the board alone won't hold — use a long dot-and-dab fixing or frame fixing that passes through the board and gap into the solid masonry behind. Timber stud: find the centre of the stud, drill a 3mm pilot hole, then drive a 40mm wood screw straight in — no plug needed. Metal stud: never use a plain wall plug or ordinary wood screw, it strips straight through 0.5mm steel — use a self-drilling metal-stud screw, or a toggle-type hollow-wall anchor rated for the load if fixing between studs. Lath and plaster: drill slowly to avoid cracking the plaster, aim for a lath or the timber behind it, and use a longer screw or a spring toggle rated for the plaster's condition, as old plaster can crumble around a fixing.
