AB-04Drill and fit the right fixing for your wallInto solid brick or block, drill a 6mm hole about 40mm deep with a masonry bit, push in a matching wall plug, then drive the screw. Into a timber stud, drill a 3mm pilot hole into the centre of the stud and use a plain wood screw - no plug needed. Into a metal stud, use a self-drilling metal-stud fixing or a toggle-type hollow-wall anchor rated for the job; never use a plastic wall plug or an ordinary wood screw, as both strip straight through 0.5mm steel. Into plasterboard between studs use a toggle or hollow-wall anchor rated for the hook's weight; into dot-and-dab plasterboard use a fixing long enough to reach the solid masonry behind the void, since a plug in the board alone will pull out; into lath and plaster, aim for a joist or stud where you can, or use a toggle fixing meant for fragile hollow walls, as old lime plaster can crumble under load. A metal stud alone won't hold anything heavy or anything that pulls away from the wall - if the hooks will carry heavy coats or bags people lean on, fit a timber noggin or pattress between the studs, or fix through to the masonry behind instead.
