KC-04Choose the right fixing for your wall typeInto a timber stud, use a wood screw at least 40mm long driven into the centre of the stud. Into a metal stud, use a self-drilling metal-stud screw or a toggle-type hollow-wall anchor rated for the load - never a plain plastic plug or an ordinary wood screw, both strip straight through 0.5mm steel. Into solid brick or block, use a matching wall plug and screw drilled to the correct depth. Through dot-and-dab plasterboard, use a fixing long enough (usually 75-90mm) to pass through the board and adhesive gap and grip the masonry behind, and on lath and plaster, always fix into the timber studs behind the laths, never the laths themselves.
