There are many different ways to attach a shelf to a drywall you will need to pick which method is appropriate for the weight of the shelf and what is going to be stored on it. If the shelf that you are going to hang it going to be light then plastic anchors will be fine, the plastic auger is like a screw and will attach into a pre- drilled hole and sit flush with the wall acting as an anchor.

You will need to make sure that the holes you drill are level. It is advisable to drill a pilot hole so that the drywall isn’t damaged when you screw the auger in place. Once you have done this for all the holes, line up the mounting bracket and attach a screw through each of the holes into the plastic anchors then simply tighten the screws and put the shelf onto the bracket.

A stronger method would be to use a molly bolt which has a set of spring or screw driven arms that will anchor behind the drywall. As you tighten up the screw, the arms open out behind the wall giving a firmer support and you will be able to put heavier items on your shelf without having to worry about the shelf collapsing.

If you want to hang a heavy weight shelf then the most secure option would be to fix the shelf to the studs, or wooden supports within the dry wall, which will create maximum strength. You will need to find the studs using a stud finder, and then mark the wall with a pencil where you want to hang the shelves. The shelves can then be screwed directly into the stud without the need for rawl plugs. As before, drill a pilot hole first, then use a screwdriver to fix the screw into the wall.
