Plastic expansion screws are used to hang items on drywall without the need for pre-drilling holes. They are suitable for hanging blinds, curtains, shelves, artwork, and other lightweight objects. The installation process is relatively simple and can be done with a screwdriver or a drill. The plastic anchors are inserted into the drywall, and then a screw is tightened inside the anchor to hold it in place. This type of anchor is not suitable for heavy items, and weight restrictions should be considered when using them.

What You'll Learn

Choose the correct tools
To install plastic expansion screws, you will need a few tools. Firstly, mark the intended location of the anchor with a pencil. You will also need a drill to make a hole in the wall for the anchor. Use an electric drill for concrete or wooden walls and a drill or an awl for drywall. If you do not have access to a drill, you can create a pilot hole using a small nail and a hammer.
Once you have made the hole, you will need a plastic expansion anchor. These often come with items intended for wall installation, but you can also purchase them separately. Plastic anchors come in various sizes and lengths, so ensure you select the correct size for your screw. Ribbed anchors are a popular choice for DIY projects as they do not require pre-drilling.
You will also need a screw for the anchor. Anchors are often sold with screws, but if purchased separately, select a screw that fits the anchor perfectly. Finally, you will need a screwdriver to tighten the screw into the anchor. A flathead or Phillips screwdriver can be used, depending on the type of screw.

Drill a hole
Drilling a hole is the first step in installing plastic expansion screws. This step requires careful preparation to ensure the screw is installed correctly and securely.
Firstly, you must select the correct drill bit size. Consult the instructions on the drywall anchor package to choose the right size. If you do not have access to the instructions, you can estimate the bit size by visually comparing the bits to the shaft of the sleeves. When in doubt, it is recommended to use a smaller bit than you think you need, as you can always enlarge the hole later if necessary.
Once you have selected the correct drill bit, fit it into your drill. Avoid drilling into wall studs or very thin/thick drywalls. Instead, insert the drill bit into the desired location on the drywall and begin drilling. Drill a precise hole to the specified depth, ensuring it is not too big, as this can cause the anchor to fail.
If you are using a nylon (plastic) anchor, you will need to create a small start hole by tapping a nail into the drywall's paper before drilling. However, if you are using a metal anchor, you can skip this step, as they are strong enough to create a hole on their own.
After drilling the hole, you can proceed to the next step of inserting the plastic anchor.

Insert the plastic anchor
To install plastic expansion screws, you'll need to insert the plastic anchor into the hole you've drilled. You can create a pilot or guide hole using a nail and a hammer, or a drill, if you have one. Once you have your hole, insert the plastic anchor. You can do this by hand, and then use a screwdriver to screw the anchor into the wall until it is flat. You don't need to use a lot of force, but you should apply firm pressure.
If you are using a self-drilling anchor, you may not need to create a pilot hole. However, some users report better results when they do create a hole first. If you are using a self-drilling anchor, you will still need to use a screwdriver to ensure the anchor is flush with the wall.
If your anchor is not flush with the wall, you can gently tap it with a hammer until it is. It is important that the anchor is flat against the wall, otherwise, it may not hold. You should also be careful not to twist too hard when screwing in the anchor, as this can strip the head.
Plastic expansion screws are suitable for hanging blinds, curtains, shelves, and artwork. They are a good choice for hanging low to medium weight items.

Screw in the metal screw
To install plastic expansion screws, you will need a plastic or metal corkscrew anchor, a hammer, a small nail, and a screwdriver.
Firstly, create a small pilot hole by tapping a nail into the drywall. Metal anchors do not need a pilot hole as they are strong enough to create a hole on their own. Next, insert the plastic anchor into the hole and use a screwdriver to turn it clockwise until it is flush with the wall.
Now you are ready to screw in the metal screw. Place the screwdriver into the notched head of the anchor and insert the metal screw. Turn the screw clockwise and tighten it with the screwdriver.
If you are installing heavy items, such as large furniture or kitchen cabinets, it is recommended to attach them firmly to wall studs instead of using plastic expansion screws.

Tighten and finish
Now that you've inserted the screw into the anchor, it's time to tighten it. Using your drill or screwdriver, turn the screw clockwise to tighten it securely in place. Be careful not to over-tighten, as this could strip the screw head or damage the anchor.
If you're using a manual screwdriver, apply firm but not excessive pressure to drive the screw into the anchor. You may need to use a hammer to gently tap the screwdriver to help tighten the screw if it's particularly tight.
Once the screw is securely tightened, take a step back and admire your handiwork. The plastic expansion screw should now be firmly in place, ready to support your chosen application.
If you're hanging something heavy, it's important to consider the weight restrictions of the anchors. While plastic expansion screws are strong and durable, they have limitations. For heavy items, it's recommended to locate the wall studs and mount your item directly to them, bypassing the need for anchors.
Finally, if you need to remove the plastic expansion screw, you can do so by following a simple reversal process. Loosen the screw by turning it counter-clockwise with a screwdriver or drill. Once loose, you can pry out the anchor using a flathead screwdriver or needle-nose pliers.
