Fixings & Hardware

Knock on it: a hollow sound usually means plasterboard on a stud frame, a solid sound means brick or block. Drill dust can also help, as red or grey dust suggests masonry.

Screws hold better and can be removed, so they suit most fixing jobs and anything under load. Nails are faster for framing, fencing and fixing panels.

It depends on the wall, the fixings, the brackets and the shelf itself; the weakest part sets the limit. Check the ratings on each and use heavy-duty fixings for heavy loads.

Zinc plated fixings resist some corrosion and suit indoor use. Stainless steel or galvanised fixings are better outdoors and in damp areas.
