Plastic wall anchors are used to hang items on hollow walls. They are specifically designed to anchor into the drywall itself, providing support for the mounted object. Ribbed plastic anchors are best suited for lighter items, while toggle bolts can support heavier loads. When installing a ribbed plastic anchor, it is crucial to first drill a pilot hole with a properly-sized bit. The anchor should then be tapped into place, either by pushing it in or using a hammer, and expanded against the drywall by driving a screw through it.

What You'll Learn
Choosing the right anchor for the job
The second factor to consider is the material of the wall. Different types of walls require different types of anchors. Drywall anchors are suitable for sheetrock or plaster, while concrete or brick walls might require a sleeve or expansion anchor. For example, ribbed anchors are suited for drywall because they offer extra grip due to the ribbing that prevents them from turning while the screw is driven. Sleeve anchors, on the other hand, are usually used in masonry or concrete because they expand as the screw is driven into them.
The third factor to consider is the type of object you are hanging. Some anchors are designed for specific applications. For example, screw-in anchors are typically used for lightweight items such as picture frames, small shelves, or light fixtures. They are easy to install and do not require pre-drilling, making them a popular choice for DIY projects.
Finally, it is important to have the right tools for the job. While a screwdriver and a hammer might suffice for basic jobs, a drill can ensure precision and ease of installation. Always refer to the manufacturer's instructions for the specific anchor you are using to determine the correct tools and techniques required.

Preparing the wall and drilling the hole
First, determine the appropriate location for the anchor on the wall. This will depend on the weight and type of object being hung. For example, conical plastic anchors are suitable for hanging pictures, attaching towel racks, or installing small shelves, but not for hanging heavy items like cabinets or large mirrors.
Next, choose the correct size of the drill bit for the pilot hole. The package of conical plastic wall anchors usually specifies the required drill bit size. If not, measure the outside diameter of the anchor's shank halfway between the screw opening and the tapered end, and select a drill bit with the same diameter. The goal is to achieve a tight fit for the anchor without making the hole too small, which would prevent the anchor from being tapped into place.
After selecting the appropriate drill bit, proceed to drill the pilot hole at the marked location on the wall. Ensure that the hole is drilled straight and deep enough to accommodate the anchor. It is essential to be cautious and precise during this step to avoid damaging the wall or drilling an incorrectly sized hole.
Once the pilot hole is drilled, carefully inspect it to ensure it is the correct size and depth. If the hole is too small, it may be necessary to enlarge it slightly using the drill bit. However, be cautious not to over-enlarge the hole, as this can compromise the holding power of the anchor.
By following these steps for preparing the wall and drilling the hole, you will create a solid foundation for installing the ribbed plastic anchors securely and safely.

Inserting the anchor
The installation process for ribbed plastic anchors is straightforward. It involves drilling a hole, inserting the anchor, and securing it with a screw.
Firstly, it is important to choose the correct size of drill bit for the pilot hole. The drill bit should match the outside diameter of the anchor shank, measured halfway between the screw opening and the tapered end. This ensures a tight fit for the anchor. Drilling a hole that is too small will make it difficult to insert the anchor, and a hole that is too large will require starting over with a new, larger anchor.
After drilling the pilot hole, gently tap the anchor into place with a hammer until it is flush with the wall. Check that the anchor fits snugly and there are no gaps between the anchor head and the wall. If there are gaps, remove the anchor and fill the hole with drywall patch before reinserting the anchor or using a larger one.
Once the anchor is securely in place, insert the screw and finger-tighten it. Then, use a screwdriver to tighten the screw further, but avoid over-tightening as this can compromise the anchor's grip or damage the wall.
Ribbed plastic anchors are ideal for hanging lighter items such as pictures, shelves, or mirrors on hollow walls. They are not suitable for heavy items as they have limited holding power and can pull out under moderate force.

Securing the anchor with a screw
Once the ribbed plastic anchor is in place, it's time to secure it with a screw. First, insert the screw into the centre of the anchor. You can do this by hand, finger-tightening it to ensure it stays in place. Then, take a screwdriver and begin to tighten the screw. It is important not to overtighten the screw, as this could damage the anchor's grip or the wall itself. Turn the screw until it feels snug but not overly tight—this will ensure a secure hold.
The screw mechanism works in tandem with the ribbed design of the anchor. As the screw is inserted and tightened, the anchor expands, pressing firmly against the wall material. This expansion increases the anchor's grip on the wall, providing strong support for the mounted object. The ribs on the anchor also play a crucial role, preventing the anchor from turning in the hole during installation. This anti-rotation feature ensures that the anchor remains securely in place while the screw is driven.
When installing a conical plastic wall anchor, it is essential to use a properly sized drill bit for the pilot hole. If the hole is too small, it will be difficult to tap the anchor into place, and if it is too large, the anchor may not fit securely. The ideal fit allows the anchor to be tapped into the hole snugly, with no gaps between the anchor head and the wall. This ensures that the anchor can expand effectively when the screw is tightened, creating a strong and reliable support system.
If you need to remove the wall anchor at any point, you must first remove the screw. This can be done using a screwdriver or a similar tool. Once the screw is out, you can use a flathead screwdriver or the claw end of a hammer to gently loosen and remove the anchor from the wall. In some cases, this process may leave small gouges in the wall, which can be filled and sanded down before repainting.

Removing the anchor
Removing plastic wall anchors can be a tricky task, and if not done properly, it can leave a big hole in your wall. The following methods can be used to remove plastic wall anchors with minimal damage to the wall.
Using a Utility Blade
This method involves cutting the face of the anchor off and then pushing the remaining part of the anchor through the wall. First, place a utility blade flat against the wall just above the anchor face. Slowly and carefully slide the blade behind the face of the anchor. Be very careful when using a utility blade as it can lead to injury. It is recommended to wear gloves for protection. Once the face of the anchor is cut off, push the remaining part of the anchor through the wall.
Using a Screwdriver and Hammer
If your plastic wall anchor is tightly embedded, you can use a screwdriver and a hammer to remove it. Choose a screwdriver that fits tightly into the anchor and give it a gentle tap with a hammer to ensure a good hold. Apply pressure and twist the screwdriver counter-clockwise to "unscrew" the anchor. Once the anchor is loose, you can grip the edge with needle-nose pliers and pull it out.
Using Needle-nose Pliers
If there are any screws still attached to the wall anchor, remove them first. Then, use the needle-nose pliers to firmly grip the inside edge of the anchor. Grab the collar or head of the anchor and give it a wiggle and a gentle tug to remove it from the wall.
Recessing the Anchor
If you are unable to remove the anchor without causing damage, you can choose to recess it into the wall. After removing the face of the anchor with a utility blade, use a small screwdriver and a hammer to push the anchor deeper into the wall. You can then patch the hole, and the recessed anchor will be invisible once the wall is repaired.
