TV-05Drill and fit the right fixings for your wallTimber stud: drill a 3mm pilot hole into the centre of the stud, then drive the bracket's coach screws (usually M8 x 60mm) straight in. Metal stud: use a self-drilling metal-stud anchor or toggle-type hollow-wall fixing rated for the load — never a plastic wall plug or ordinary wood screw, they strip straight through 0.5mm steel. Between studs on plasterboard: use a toggle or hollow-wall anchor rated for the TV's weight, not a plug. Solid brick or block: drill with a hammer drill and masonry bit sized to your plug, to at least 40mm depth, then fit the plug and screw. Dot-and-dab plasterboard: use fixings long enough (often 90-120mm) to pass through the plasterboard, the air gap and the adhesive dabs into the solid masonry behind — plasterboard alone won't hold a TV. Lath and plaster: locate the timber studs behind the laths first and screw into those; drilling into bare lath and plaster can crack the old plaster, so go slowly with a sharp pilot hole. A full-motion arm bracket pulls harder on the wall than a fixed one — on metal studs or dot-and-dab, fit a timber noggin between the studs or fix through to masonry behind instead of relying on the plasterboard alone.
