Hanging closet hooks is one of the simplest ways to expand your storage space. You will need hooks, drill and bits, a steady hand, a stud finder (optional), a hammer (optional), & wall anchors (optional).
Identify whether your closet walls are drywall, masonry, or concrete. Choose hooks. Choose hooks according to the composition of your walls and how much weight you want them to hold. Ask at your hardware store for advice or research them online.
Hooks that must be hammered into the wall can't be used on masonry or concrete.
Locate a stud. If your walls are drywall, you'll need to locate a stud, or the frame behind the drywall. You can use a stud finder, or you can simply tap on the wall and determine which points sound the least "hollow."
Drill a hole into the wall (or stud) that's equal to the depth of your hook's screw. Make sure you use the correct size drill bit. You'll want to use one that's slightly smaller than the screw for drywall, and slightly larger than the screw for everything else. Hammer in the hook. If you have a hook that can be hammered, simply hammer it into the hole you just drilled. Install a wall anchor. If you have a masonry or concrete wall, you'll need to install a wall anchor in the hole. Tap the anchor into place using a hammer, then screw in the hook. Hang 'em high. Gather up all the odds and ends off your closet floor—and hang 'em high. * Fact: Hooks have been in use since Paleolithic times.
