The lighter objects can be hung between studs. but to hang or hold a heavy object into a wall (usually called drywall, or gypsum wallboard), It is necessary to screw into the framing stud behind the drywall or plaster, or use a screw hollow wall anchor or heavy duty concrete anchors.

The drywall (gypsum wallboard) is not strong enough to hold a screw to hang something from your wall or ceiling, and plaster is too hard and brittle to accept screw threads without crumbling.

The following is a practically tips of installation for screws and anchors in walls.

Prepared Materials and tools:
Measuring tape
Screwdriver (screw driver)
Pencil
Electrical Drill driver and bit (for sleeve anchor)
Hammer (optional)
Appropriate anchors, screws and studs


Install a Self Drilling Anchor
Use self drilling anchors in gypsum wallboard 3/8 to 5/8 inch thick for light to medium loads, such as a shelf bracket or towel bar on a wall.

re. Usually a 1/8-inch bit works well for this.

Turn the screw into the pilot hole, starting by hand. Use pliers if this becomes too difficult.
