Plastic hollow wall plugs, also known as drywall anchors, are used to hang light-duty items such as artwork or floating shelves. They can be used in drywall, plaster, concrete, or hollow walls. Before installing a plastic hollow wall plug, it is important to check that the drywall is in good condition, as an anchor can slip out of patched or water-damaged drywall. To install the anchor, start by drilling a pilot hole in the wall with a drill bit smaller than the width of the anchor. Then, place the anchor in the hole and tap it gently into the wall with a hammer or rubber mallet until it is flush with the wall. Finally, use a screwdriver to drive the screw securely into the anchor.

What You'll Learn

Drilling a pilot hole
Select the Appropriate Drill Bit:
Before drilling, ensure you have the correct size drill bit for your plastic hollow wall plug. The drill bit should be slightly smaller than the width of the wall plug. Check the packaging of your wall plug for the recommended bit size. Using the right size is essential to ensure a secure fit.
Choose the Right Drill Type:
For drilling into walls, it is recommended to use a power drill, preferably a cordless drill for ease of handling. Ensure the drill is set to the appropriate speed and torque settings for the material you are drilling into.
Mark the Drill Spot:
Using a pencil, carefully mark the spot on the wall where you will drill the pilot hole. Make sure the spot is level and in the correct position for your specific task. This step ensures that your hole is drilled in the desired location.
Drill Slowly and Steadily:
Start drilling at a slow and steady pace. Apply gentle but constant pressure to the drill, allowing the bit to penetrate the wall surface gradually. Be cautious to avoid applying too much force, which could cause the drill bit to wander or the wall to crack.
Maintain a Perpendicular Angle:
Hold the drill as straight as possible, maintaining a perpendicular angle to the wall. This ensures that the pilot hole is drilled straight and does not veer off at an angle, which could cause issues when inserting the wall plug.
Clear Away Debris:
As you drill, periodically remove the drill bit from the hole to clear away any accumulated debris. This prevents the drill bit from becoming clogged and ensures a cleaner hole.
Check Hole Depth:
Drill to a depth that matches the length of your plastic hollow wall plug. Refer to the packaging for the recommended depth. It is crucial to ensure the hole is neither too shallow nor too deep for the wall plug to be securely installed.
By following these steps, you will successfully drill a pilot hole that is correctly sized, positioned, and angled, providing a solid foundation for installing your plastic hollow wall plug. Remember to work carefully and wear the appropriate safety gear, including eye protection, when operating power tools.

Inserting the anchor
Firstly, it is important to select the correct drill bit size. Choose a drill bit that is slightly smaller than the width of the anchor. This ensures a tight fit. The drill bit size should be specified on the packaging of your plastic hollow wall plugs, so be sure to check this before drilling. It is also important to drill the hole with precision. Ensure the drill bit does not exert a side load onto the hole walls, as this can cause the hole to mill, resulting in a loose anchor.
Once you have drilled your hole, it is time to insert the anchor. Push the anchor into the hole, ensuring it is firmly in place. You may need to use a small hammer to gently tap the anchor into the wall until it is flush with the surface. Be careful not to use excessive force, as this could damage the wall or the anchor.
If you are using collarless anchors, you may need to apply more force to drive them into the hole. You can use a hard tool to push them in or gently tap them with a hammer. Collarless anchors have a slightly smaller diameter than the hole, so they may require some extra force to ensure a tight fit.
For plastic toggle anchors, there is a specific technique to follow. Use your index finger to push in the toggle so that it collapses into a "barrel" shape. This allows it to be easily inserted into the pre-drilled hole.
Once the anchor is in place, you can start screwing in the fastener. Do this gently to avoid pushing the anchor through the wall. The fastener should bite easily, so there is no need to apply too much force.

Tapping the anchor into place
Start by placing the anchor in the pre-drilled pilot hole. It's important to ensure the hole is slightly smaller than the anchor to achieve a snug fit. Gently push the anchor into the hole, using your fingers or a suitable tool, until it is firmly seated.
Now, it's time to begin tapping. Hold the anchor in place with one hand and use a small hammer to gently tap on the exposed end. Tap with light force and pay close attention to how far the anchor sits in the wall. You want the anchor to be flush with the wall, neither protruding nor recessed.
Continue tapping gently until the anchor is almost at the desired depth. The final step is to use a rubber mallet to gently nudge the anchor into its final position. The rubber mallet provides a softer impact, reducing the risk of damaging the wall or the anchor itself.
If your anchor came with a fastener, you can start screwing it in gently at this point. This will help secure the anchor in place and ensure it doesn't move around. Be careful not to over-tighten the fastener, as it may cause the anchor to shift or damage the wall.
For plastic hollow wall plugs, the tapping process is relatively straightforward. Just remember to go slowly and use gentle force to avoid any damage. Once the anchor is in place, you'll be ready to hang your desired item securely, knowing it will hold firmly in place.

Using a screwdriver
To install a plastic hollow wall plug, you will need a screwdriver, a drill, drill bits, and a hammer.
First, use a drill to create a pilot hole in the wall. The hole should be smaller than the width of the wall plug. If you don't have a drill, you can use a screwdriver to create the hole by pressing the tip of the screwdriver against the wall and twisting it back and forth.
Next, insert the plastic wall plug into the pilot hole. You can do this by hand or use a hammer to gently tap it into the wall until it is flush with the wall.
Now, take your screwdriver and place it into the notched head of the wall plug. Turn it clockwise and apply firm pressure to draw the wall plug into the wall. Be careful not to twist too hard, or you may strip the head of the plug.
Finally, add the provided screw to the wall plug and tighten it with your screwdriver. Turn the screw clockwise until it is secure, but be careful not to overtighten it.
Additionally, if you need to remove the wall plug, you can use a small flat-head screwdriver to push it through the wall.

Choosing the correct anchor
Wall Type
The type of wall you are working with is an important factor in choosing the appropriate anchor. Different walls have different structural characteristics, so it is essential to select an anchor that is compatible with the wall material. For example, if you have a drywall or plaster wall, plastic drywall anchors are usually suitable. In contrast, metal or toggle anchors are recommended for brick or concrete walls. Consider knocking on the wall to determine its type—if it sounds hollow, it is likely drywall, and if it sounds solid, it is probably plaster or masonry.
Weight of the Item
One of the most critical factors in choosing an anchor is ensuring that it can support the weight of the item you intend to hang. Different anchors have varying weight capacities, so selecting one that can safely bear the load is essential. For instance, plastic anchors are typically recommended for lightweight items such as pictures or decorative shelves, while metal anchors or toggle bolts are more suitable for heavier objects like cabinets or mirrors. Always refer to the manufacturer's specifications to determine the weight limit of the anchor.
Wall Thickness
Consider the thickness of your wall when selecting an anchor. Hollow wall anchors, for example, are designed to expand in the wallboard cavity, so they require sufficient space to function properly. If you have a double plasterboard or a wall with inconsistent thickness, you may need to choose an anchor that accommodates these variations.
Installation Requirements
Some anchors have specific installation requirements. For instance, some anchors, like self-drilling anchors, do not require pre-drilling, while others, like plastic anchors, need a pilot hole. Additionally, certain anchors may require special tools for installation, so ensure you have the necessary equipment before starting your project.
Environmental Conditions
Consider the environmental conditions in which you are working. For example, chemical anchors are not suitable for installation in cold weather. If you are installing anchors outdoors or in a humid environment, choose anchors that are resistant to corrosion or rust.
By considering these factors—wall type, weight capacity, wall thickness, installation requirements, and environmental conditions—you can make an informed decision about choosing the correct anchor for your specific needs. Remember to follow the manufacturer's instructions and guidelines for a safe and secure installation.
