Drywall — especially the commonly used 1/2-inch-thick size — supports heavy weights when the shelving is properly installed. You can install heavy shelves with confidence that they will remain stable and secure, by using brackets. Drive screws through the holes in the bracket into the pilot holes in the shelf. This can be 5 to 10 pounds, but keep in mind that the drywall is an extremely brittle material and, it is not strong enough to hold the weight for a longer period of time. Simple Answer: NO – A screw directly into drywall will not hold. You need to use some type of picture hanging hardware to hang a heavy picture securely. The threads of a screw into only drywall, without an anchor, will NOT permanently hold in the drywall. It will just pull right back out sooner or later. Hollow-Wall Anchors: How to Hang Something on the Wall Without a Stud. Whether fastening a framed picture, mirror, shelf, or curtain rod to a wall, it's always best to screw or nail directly into a wall stud. Unfortunately, studs are seldom, if ever, positioned exactly where you need them, but that's okay. The nails drive into drywall and plaster walls at an angle, which allows them to use the wall surface as leverage and support. These are perfect for hanging picture frames up to about 20 pounds. If you have a picture that is heavier than that, it is best to use a flat mounted hook and anchor.
Find a Stud A nail in just drywall can't hold more than a few pounds of weight, but a thin nail in a wood stud can typically hold up to 20 pounds and several coarse threaded wood screws in wood studs can typically hold up to 100 pounds or more.

The best way to reinforce a drywall patch is to use backing boards to make the patch as strong as the drywall itself. Cut a piece of drywall to fit over the hole. Place the drywall patch over the hole and trace the outline with a pencil. Cut out the tracing with a keyhole saw or a drywall saw.
Ideally, you should attach floating shelves (or anything else you're hanging) to a wall stud, as this will give you the most supportive base for your project. A stud finder—a hand-held device that uses a magnet to detect metal, such as the nails and screws in the wall studs of your home—can help you locate these.
A floating shelf is strong, quick to build, with no visible supports and made from only two parts. These shelves are handsome, easy to build and inexpensive. And they're strong even though they have no visible supports. They appear to float on the wall, no clunky hardware or brackets.
Locate the mounting screws on the floating shelf. Pull the shelf off from the mounting board away from the wall. Slide a stud finder along the wall just above the mounting board where the shelf was mounted to locate the studs. Align the shelf with the mounting board.
