Drywall anchors are used to attach items to walls when wall studs are unavailable. They can be made of plastic or metal, with metal versions being stronger. Plastic expansion anchors have a conical shape and raised rings or barbs along their body to improve grip. They are often included with items intended for installation on a wall or ceiling. When a screw is driven into the anchor, the shank of the anchor splits and expands into flanges or wings that grip the interior of the drywall, helping to secure the anchor and prevent it from pulling out easily. To install a plastic wall anchor, you will need to create a pilot hole, stick the anchor in the hole, and tap it into place until it is flush with the wall. Then, use a screwdriver or drill to screw the anchor into the wall.

What You'll Learn
Drilling a pilot hole
Firstly, determine the location of your pilot hole. Mark this spot with a pencil to ensure accuracy. It is important to note that you should avoid drilling into a wall stud. If you are unsure, use a stud finder to check for the presence of wood. If a stud is present, opt for a different location or use screws directly into the stud.
Now, select the appropriate drill bit for creating the pilot hole. The hole should be smaller than the width of the anchor. If you are using a self-drilling anchor, the packaging will specify the required size of the pilot hole. Choose a drill bit that corresponds to this size.
With your drill bit selected, it's time to drill the pilot hole. Place the drill bit at the marked location and apply gentle pressure to create the hole. Ensure the hole is deep enough to accommodate the anchor, leaving an extra 1/8 inch for the protrusion of the screw out the back. Be cautious not to drill too deeply or widely, as this can affect the anchor's grip. If you encounter a solid wall with no cavity, move the drill bit in and out to prevent dust from packing into the hole and impeding the anchor's insertion.
Once the pilot hole is drilled, it's time to insert the anchor. Tap the anchor gently into the hole using a hammer or rubber mallet until the collar of the anchor is flush with the wall surface. Ensure that the collar does not sink below the surface. This step ensures that the anchor is securely seated and ready for the screw to be inserted.
By following these steps, you will effectively drill a pilot hole for your plastic wall anchor, setting the foundation for a sturdy and secure installation.

Using a hammer to tap the anchor into the hole
When installing a plastic wall anchor, you'll need to start by creating a pilot hole. This can be done by tapping a nail into the drywall or by using a drill. The hole should be smaller than the width of the anchor.
Now, for the hammering part:
Using a hammer, carefully tap the anchor into the hole until the collar of the anchor is flush with the wall surface. Be sure not to hammer too forcefully, as this may cause damage to the wall or the anchor. The collar of the anchor should sit neatly on the surface of the wall, providing a stable base for the item you will be attaching. It is important that the collar does not sit below the surface of the wall, as this may affect the security of the anchor.
A rubber mallet is the best tool for this job, as it will reduce the risk of damage to the wall or anchor. However, if you do not have a rubber mallet, a small finish nailer or even a regular hammer can be used, provided you are careful and gentle with your taps.
If you are using a strap-type toggle anchor, you will need to insert the toggle through the pilot hole and then pull the straps towards you, so the toggle rests against the back of the wallboard. This will provide support for the anchor. Once the toggle is in place, slide the anchor collar along the straps and against the wall surface.
For a screw-type toggle bolt, the process is slightly different. First, remove the spring-loaded toggle from the screw. Then, insert the screw through the mounting hole of the item you are installing. Finally, spin the toggle back onto the screw, ensuring it is oriented to fold down towards the screw head.

Using a screwdriver to set the screw
To install a plastic wall anchor, you will need to use a screwdriver to set the screw. This process will differ depending on the type of anchor you are using.
For plastic ribbed anchors, you will need to first drill a hole, insert the anchor, and tap it into place with a hammer. Then, insert your screwdriver and tighten the central screw. As you do so, the collars on the backside will spread out and clamp the wall tight.
If you are using a self-drilling anchor, place the tip of the anchor into the pilot hole, then use a screwdriver to twist it clockwise, sinking it deep into the drywall. Self-drilling anchors can also be screwed in with a handheld screwdriver.
For nylon (plastic) anchors, you will need to create a small start hole by tapping a nail into the drywall. Then, place a Phillips or flat-head screwdriver into the notched head of the anchor and turn it clockwise, applying firm (but not hard) pressure to draw the anchor into the drywall.
Winged plastic expansion wall anchors are easy to install and do not require pre-drilling. Simply insert the anchor into the hole and use a screwdriver to drive the screw securely into the anchor.

Selecting the right type of anchor
When selecting a plastic wall anchor, it's important to consider the weight of the item you plan to hang and the type of wall you're working with.
Plastic wall anchors are typically used for lightweight items such as picture frames, small shelves, or light fixtures. They are often made of nylon and have a sharp thread and a pointed tip on one end, with a flange on the other. The flange prevents the anchor from being pulled through the wall. Plastic anchors with more ribbing provide greater friction, reducing the likelihood of them pulling out of the wall.
If you're hanging something heavy, like a shelf or a TV set, you may need to use multiple anchors to distribute the weight evenly and prevent the fasteners from pulling out. In this case, larger anchors that accept bigger screws are generally more secure. Metal anchors, such as traditional metal toggle bolts, are often a better choice for heavier items as they can support more weight.
The type of wall you're working with will also determine the type of anchor you need. For example, drywall anchors are designed for use in drywall, while masonry anchors are meant for brick or concrete walls.
Some common types of plastic wall anchors include:
- Self-drilling anchors: These anchors feature sharp teeth on one end, eliminating the need for pre-drilling. They provide greater support than expansion anchors but can damage drywall if overtightened.
- Winged expansion anchors: These anchors have wings that prevent them from pulling out of the wall.
- Ribbed plastic anchors: These anchors have raised rings or barbs along their body to improve grip.
When in doubt, it's always best to consult the instructions on the packaging of the anchor or the item you're installing.

Removing a sleeve-style anchor
First, it is important to understand the basic structure of a sleeve-style anchor. These anchors typically consist of a plastic sleeve with a flange that rests flat against the face of the drywall. The screw is inserted into the hollow centre of the sleeve and drilled in to secure an item to the wall.
To begin the removal process, use a manual screwdriver or cordless drill to remove the screw from the plastic sleeve. This will involve turning the screw counter-clockwise until it is free. If the screw is difficult to remove, you may need to use a flathead screwdriver for additional leverage.
Once the screw is removed, you can focus on the plastic sleeve. Use a flathead screwdriver to pry up the edge of the flange, which is the part of the sleeve that rests against the wall. Gently insert the screwdriver under the flange and apply slight upward pressure to lift it away from the wall surface.
With the flange pried up, you can now grab onto it with a pair of needle-nose pliers. Grip the flange securely and pull the anchor sleeve straight out of the wall. It may require some force, but be careful not to damage the surrounding wall material.
If the anchor sleeve is stubborn and refuses to come out, there are a few alternative methods you can try. One method involves using a drill with a cutting edge. Score the edges of the drywall around the anchor to weaken its hold. Then, place a screwdriver over the anchor and tap it lightly with a hammer, pushing the anchor further into the wall. This will allow you to spackle and paint over the area, hiding any signs of the anchor.
Another method involves using an awl, a utility knife, or a punch. Insert the awl or knife into the anchor and turn it as if screwing it into the hole. This will help to loosen the anchor's grip, and you may then be able to pull it out with pliers. Alternatively, you can use a punch and a hammer to drive the anchor through the wall to the other side.
In some cases, you may need to cut a small section of the drywall around the anchor and remove that portion of the wall entirely. This will require repairing the wall by spackling over the hole and sanding it smooth before repainting.
When removing sleeve-style anchors, it is important to be cautious and patient. Assess the condition of the anchor and select the appropriate removal method to avoid causing unnecessary damage to your walls.
