My wife wanted big hooks on the sides of her closet to hang clothes on hangers. Typical coat hooks were too small. She wanted to hang lots of hangers on it. These hooks were perfect for this purpose. I used one on each side of the closet. I mounted them to hollow drywall using a hand screwdriver. They attach easily and feel secure. Extra deep thread for a firm hold on drywall without stripping. Please note each hook weighs 20 pounds. when used in hollow plasterboard. (Β£40 for a pair of hooks used together).
