Plastic wall anchors are available in a variety of sizes and designs, with the most common type being plastic expansion anchors. They are suitable for hanging lightweight items such as pictures, small shelves, or light fixtures. The size of the plastic wall anchor depends on the weight capacity and wall type. For example, plastic anchors are best for lightweight items, while zinc or metal anchors are ideal for heavier items. Larger plastic anchors will accept larger screws and have greater holding capacity. Self-drilling plastic wall anchors are also available, which can be screwed back out and reused.

What You'll Learn
Plastic wall anchors are best for lightweight items
Plastic wall anchors are a popular choice for hanging lightweight items. They are easy to install, cost-effective, and can be used with a variety of foundation materials such as concrete, drywall, block, and brick. When selecting a plastic anchor, it is important to consider the weight of the item being hung and choose an anchor with sufficient holding power.
Plastic wall anchors come in various designs and sizes, with different weight capacities. Lightweight plastic drywall anchors can typically support weights ranging from 10 to 15 pounds, while stronger bolts can handle more than 200 pounds. It is recommended to use only a quarter of the maximum weight capacity per anchor and, if possible, use multiple anchors for added support.
Plastic ribbed anchors, also known as screw-in anchors, are commonly used for hanging lightweight objects. They feature a sharp thread, a pointed tip on one end, and a flange on the other to prevent them from pulling through the wall. These anchors are available in various sizes and lengths and are installed by drilling a hole, inserting the anchor, and tapping it into place.
Winged plastic expansion anchors are another type of plastic wall anchor suitable for lightweight applications. The wings on these anchors prevent them from pulling out of the wall. These anchors are easy to install and do not require pre-drilling, making them a popular choice for DIY projects.
When using plastic wall anchors, it is important to follow the correct installation process. This typically involves drilling a pilot hole in the wall that is smaller than the width of the anchor. The anchor is then inserted into the hole and tapped into place using a rubber mallet or a hammer. Finally, a screw is driven into the anchor to secure it in place.
Plastic wall anchors are an excellent choice for hanging lightweight items such as picture frames, small shelves, light fixtures, mirrors, curtain rods, and decorative clocks. They provide a secure hold and can be used on various wall surfaces, making them a versatile and convenient option for homeowners and DIY enthusiasts.

Larger plastic anchors accept larger screws
Plastic wall anchors are commonly used for hanging lightweight items such as pictures, small shelves, or light fixtures. They are also used for cabinet doors, where they provide a flush, smart look that is easy to install and remove.
When choosing a plastic wall anchor, it is important to consider both the wall type and the weight capacity of the anchor. Plastic anchors are typically used for lightweight applications, while metal or zinc anchors are more suitable for heavier items.
Larger plastic anchors can accept larger screws, providing greater holding capacity and strength. The more heavily "ribbed" anchors offer the greatest gripping strength, regardless of the wall material. When a screw is installed into a plastic anchor, it expands and exerts force against the material it is installed in.
To install a larger plastic anchor, a larger hole may need to be drilled in the wall compared to smaller anchors. It is important to use the largest size anchor that is suitable for the task, as this will provide greater strength. Once the hole is drilled, the anchor is inserted, and a screwdriver is used to drive the screw securely into the anchor.
It is worth noting that plastic anchors are not suitable for heavy loads, even when used in concrete. For heavier applications, metal or zinc anchors are recommended.

Plastic expansion anchors are commonly used
Plastic expansion anchors are available in various sizes, colours, and designs, with larger anchors accepting larger screws and providing greater holding capacity. The more heavily "ribbed" an anchor is, the greater its gripping strength will be, regardless of the wall material.
Plastic expansion anchors are easy to install and do not require pre-drilling, making them a popular choice for DIY projects. To install, simply drill a hole, insert the anchor, and tap it into place with a screwdriver. However, it is important to note that overtightening plastic expansion anchors can damage drywall and make the hold less secure.
While plastic expansion anchors are commonly used, they are the least strong type of anchor, with a pull-out strength of around 30 pounds in concrete and as little as 10 pounds in drywall. Therefore, it is important to consider the weight of the object being hung and the type of surface the anchor is installed on to ensure the anchor is strong enough for the application.

Self-drilling plastic wall anchors can be screwed back out
When it comes to hanging items on your walls, it's important to choose the right type and size of wall anchor for the task. Plastic wall anchors are typically used for lightweight items, such as pictures, small shelves, or light fixtures. They are easy to install and do not require pre-drilling, making them a popular choice for DIY projects.
Self-drilling plastic wall anchors are a specific type of plastic anchor that can be used for projects requiring drilling through drywall. They feature sharp teeth on one end, eliminating the need for pre-drilling. However, it's important to be cautious during installation as overtightening can damage the drywall and reduce the security of the hold.
When selecting the appropriate size of plastic wall anchor, it's crucial to consider the diameter of the screw you will be using. Choose an anchor that is slightly smaller than the screw's diameter to ensure a tight grip. Additionally, the size of the anchor should correspond to the weight of the item you intend to hang. Larger plastic anchors can accommodate larger screws and provide greater holding capacity.
It's worth noting that while self-drilling plastic wall anchors offer convenience and reusability, they may not be suitable for all projects. In some cases, users have reported issues with these anchors pulling up crumbly drywall during installation. This issue can be mitigated by drilling a small pilot hole before screwing in the anchor, particularly if you suspect the presence of a wood stud behind the drywall.

Metal anchors are better for heavier items
When it comes to hanging items on walls, wall anchors are essential when it's not possible to hit a stud. Nails and screws can easily slip out or cause the wall to break apart if an anchor isn't used. Therefore, choosing the right type of anchor and installing it correctly are crucial.
Plastic drywall anchors are suitable for hanging lightweight items such as pictures, small shelves, or light fixtures. They are commonly included with brackets, shelves, and large picture frames. Plastic anchors are typically sleeves that a screw is driven into. This sleeve is set into a pilot hole in the wall and grabs the sides of the wall as the screw is driven into the sleeve. Larger plastic anchors will accept larger screws and thus have greater holding capacity. The more heavily "ribbed" plastic anchors will give the greatest gripping strength, regardless of the wall material.
On the other hand, metal anchors are better for heavier items such as large shelving units, roof rafters, and heavier shelves. Metal anchors can be used in various applications like cement, wood, drywall, and concrete blocks. They are also available in multiple designs, such as a simple sleeve, toggle bolt, bolt anchors, and molly bolts. For example, a molly bolt has metal teeth that spring out and embed into the back of the wall material.
It's important to note that the type of wall you're working with will determine the type of wall anchor you need. Additionally, when installing anchors, it's crucial to use the right size screw for the anchor and to be careful not to overtighten the screw, as this can damage the anchor and reduce its security.
