Plastic anchors are used to hang items on walls, but they can sometimes break or pull out of the wall. This can be due to various reasons, such as using the wrong type of anchor for the wall material, not preparing the hole correctly, or using the wrong size of screw. To avoid breaking a plastic anchor, it is important to choose the right type of anchor for the specific wall material, ensure that the hole is drilled to the correct size, and use the appropriate size of screw for the anchor.
| Characteristics | Values |
|---|---|
| Hole size | The hole should be the same width as the end of the plastic anchor. |
| Hole depth | The hole should be smaller than the anchor so that it doesn't sit flush with the wall. |
| Wall material | Avoid drilling into solid materials like wooden or metal support beams. |
| Anchor type | Use winged plastic anchors or snap toggle bolts for heavier loads. |
| Screw size | Ensure the screw is not too small or too large for the anchor. |

What You'll Learn
Avoid drilling into a stud or beam
When installing plastic drywall anchors, it is important to avoid drilling into a stud or beam. Here are some tips to help you avoid this issue:
Firstly, before you start drilling, use a stud finder to ensure there isn't a stud behind the wall. This simple step can save you a lot of trouble. If you do encounter a stud, move to a different spot to drill or, if possible, screw directly into the stud, provided you haven't drilled too far into it.
If you're drilling into drywall, make sure the hole you create is the correct size. It should be roughly the same width as the end of the plastic anchor. If the hole is too small, the anchor may not fit, and if it's too big, the anchor won't expand enough to grip the wall, causing it to fall out.
When drilling into drywall, use a drill bit that is the same size as specified on the anchor's packaging. If you drill with a bit that is too large, you risk making the hole too big, which can cause issues with the anchor's grip.
Additionally, consider the type of anchor you are using. Some anchors, such as winged anchors, are designed to grip the drywall by splitting in half when the screw is inserted. These anchors can be a good choice for drywall as they provide strong support.
If you're dealing with plaster walls, consider using self-drilling anchors. These anchors can easily penetrate the tough plaster material and are less likely to break during installation.
By following these tips, you can avoid the issue of drilling into a stud or beam and increase the chances of a successful plastic anchor installation.

Use the correct drill bit size
When installing plastic wall anchors, it is crucial to select the correct drill bit size to prevent the anchors from breaking. The drill bit you use should correspond to the size of the anchor you are installing. Using a drill bit that is too large can cause the anchor to fit too loosely, resulting in insufficient grip and stability. Conversely, a drill bit that is too small can lead to excessive force being applied during installation, causing the anchor to deform or break.
To ensure you are using the correct drill bit size, carefully read the instructions provided with your specific plastic anchors. In some cases, the package may even include a recommended drill bit or a pilot hole guide. Following these instructions is essential to ensure the proper fit of your anchors.
If you are using winged plastic anchors, which split in half to grip the drywall, it is important to ensure that the drill bit you are using is slightly smaller than the collar or lip of the anchor. This will ensure that the anchor sits securely in the hole without slipping too far into the wall.
Additionally, consider the material you are drilling into. For example, if you are drilling into drywall, you may need to adjust your technique slightly. Drywall is chalky and brittle, so you can wiggle the drill bit to create a slightly larger hole if needed. On the other hand, if you are drilling into plaster, self-drilling metal anchors are often recommended as they can more easily penetrate this tougher material.
By selecting the appropriate drill bit size and considering the unique characteristics of the installation material, you can effectively avoid breaking plastic anchors during installation.

Choose the right anchor type for your wall material
Choosing the right anchor type for your wall material is crucial to avoid breaking plastic anchors. The type of wall you're working with determines the type of wall anchor you need.
If you're working with drywall, also known as plasterboard, plastic drywall anchors are suitable for hanging lightweight items such as pictures. For heavier items like shelves, metal or toggle anchors are recommended. Toggle bolts, composed of a bolt and a threaded, spring-loaded toggle, are simple and reliable for securing larger cabinets or wooden pieces to drywall. They require a hollow space behind the wall, so they won't work with brick walls but are suitable for concrete blocks.
For plaster walls, which are made by nailing strips of wood (laths) over wall studs and then covered with plaster, toggle bolts can be useful when wall thickness varies. Their long screws make them adjustable, ensuring a secure fit.
For masonry, which includes brick and concrete, plastic sleeve anchors can be used for light-duty applications. Coarse-threaded screws designed for masonry can be used without an anchor or pilot hole.
Additionally, consider the weight of the items you're hanging. Plastic anchors are typically used for lightweight objects, while metal anchors are better for heavier items. Always check the weight ratings specified on the anchor packaging, and stay within the recommended limits.

Ensure the anchor is the correct size for the hole
When installing plastic anchors, it is crucial to ensure that the anchor is the correct size for the hole. This means that the hole should be slightly smaller than the anchor to ensure a tight fit. If the hole is too small, the anchor may not fit at all, and if it is too large, the anchor may not have enough grip and can pull out or break.
To achieve the correct hole size, it is recommended to use a drill bit that is the same size or slightly smaller than the anchor. This will create a hole that is the exact size of the anchor or slightly smaller, ensuring a snug fit. It is important to be cautious and not make the hole too big, as this can compromise the anchor's grip and stability.
The type of anchor used also plays a role in determining the appropriate hole size. Some anchors, such as self-drilling anchors, can be drilled directly into the wall without a pilot hole, while others may require a pilot hole first. When using a pilot hole, ensure that it is smaller than any collar or lip on the anchor to prevent the anchor from slipping into the wall.
Additionally, the material of the wall should be considered. For example, drywall is chalky and brittle, allowing a little give for the anchor to fit through. On the other hand, plaster walls may require self-drilling anchors specifically designed to penetrate the tough plaster material. When drilling into brick, it is advisable to use painter's tape on the drill bit to prevent drilling too deep.
By following these guidelines and considering the appropriate anchor type, drill bit size, and the wall material, you can ensure that your plastic anchor is the correct size for the hole and avoid issues such as breakage or insufficient grip.

Use the correct size screw for the anchor
When installing plastic anchors, it is important to use the correct size screw for the anchor. If the screw is too small, it will not expand the anchor enough to grip the wall. This will cause the anchor to fail to hold any weight and pull out of the wall.
On the other hand, if the screw is too large, it can damage the anchor and/or the surrounding material, which can also cause the anchor to fail. The screw may also be unable to fit into the anchor, and the force applied when trying to insert it may cause the anchor to break.
The screw must fit snugly into the anchor for the anchor to work as intended. When in doubt, it is best to follow the manufacturer's instructions for the recommended screw size for the anchor.
Additionally, it is important to consider the length of the screw as well. If the screw is too long, it can cause the anchor to pull out of the wall as you tighten it. Therefore, it is crucial to ensure that the screw length is appropriate for the depth of the wall and the anchor.
Using the correct size screw is essential to avoid breaking plastic anchors and ensuring their effectiveness in holding weight.

Frequently asked questions
Only use plastic anchors for drywall installed over an empty cavity. If there is a wooden or metal support beam behind the drywall, the anchor will deform and break.
The hole may be too small. Try wiggling the drill to make the hole bigger.
The pilot hole may be too big. Most plastic anchors are tapered, so they should fit tightly in the hole. If the hole is too big, the anchor won't expand enough to bite into the surrounding hole.
If the anchor is totally flush with the surface, tap it a little deeper into the wall and patch over it.
