How to Install Anchors for Screws in a Hollow Wall

Use wall anchors to mount objects where no stud is available.

Plastic wall anchors often are used to hang lightweight objects like frames or decorations in drywall locations where it is difficult or impossible to mount them into a wall stud. Anchors are shaped like screws, but with a hollow center where screws are inserted. When the screw enters the wall anchor, the plastic is forced apart, allowing it to bite into the drywall. This gives the screw the ability to carry more load than otherwise possible in drywall alone. Wall anchors are made from simple plastic for light-duty use, and a metal composite for medium-duty use like shelves or heavy frames.

Things You'll Need

• Pencil
• Drill
• Drill bit
• Wall anchors
• Hammer
• Screws
• Screwdriver

Instructions

1. Make a mark with a pencil at all the locations where wall anchors are needed. Try to get them evenly spaced in the hollow drywall areas.

2. Drill the holes in the drywall for each wall anchor. Use the proper drill bit for the anchors you're using. The recommended bit is often noted on the anchor package. The holes should be just large enough to fit the anchors.

3. Press the anchors into the drywall holes. Don't force them, which can damage the holes or bend the anchors. Lightly tap the anchors in with a hammer if they don't slip into the drywall with mild pressure. Press or tap the anchor until it is flush and smooth with the drywall face.

4. Thread a screw into the anchor partly by hand. Use a screwdriver to firmly tighten it into the anchor.

Tips & Warnings

• If an anchor is damaged while trying to insert it, or it was originally manufactured poorly, don't use that anchor.

• If the anchor is too loose, use a larger anchor, or fill the hole with caulk and press the anchor into the hole. If using caulk, let it firm up slightly around the anchor before inserting a screw.

• Don't use a power drill or electric screwdriver when inserting the screw into the anchor. This may push the screw into the anchor too abruptly, causing the anchor to spin and loosen or push entirely through the drywall.

• Don't wiggle the drill bit to try to make the hole large enough for the anchors in lieu of using the proper-sized bit. This will round out the hole and make it harder for the anchor to make a firm connection.
