What Are Wall Anchors, and How Are They Used for Retaining Wall Repair?

When repairing your walls, it can seem difficult to find reliable tools that will efficiently retain the repairs. If you’re searching for a device that will ensure your wall repairs remain and allow you to hang objects efficiently, wall anchors are your best option.


What are Wall Anchors?

Wall anchors are long rods driven through the retaining wall and attached to anchors that have been planted into the earth behind the wall. The rods are then tightened and a wall plate is added, bringing the wall back to the desired position.


When to Use Wall Anchors

Wall anchors are typically used to help overcome retaining wall issues. In some cases, we recommend wall anchors or helical tiebacks to restore the strength and stability of the wall.


Common Types of Wall Anchors

Within the hollow and expansion categories lies many different types of wall anchors. Here are just a few of the most common kinds:

Plastic Expansion

Plastic expansion anchors are the most common type of wall anchor sold today. They typically come packaged with hardware for any wall hangings over a pound or so. As with all expansion anchors, they are only as strong as the installation material they are anchored to, making them only a slight upgrade over screws alone. For this reason, they are not a good fit for drywall and similar materials.


For a little additional strength over what plastic expansion anchors provide, threaded wall anchors are a good option. While similar in shape and function, these anchors are a much stronger, more robust option.

As their name suggests, these wall anchors have large threads around the outer surface. Along with the pointed tip, these threads grab into the surface material to create a secure attachment point. These elements make the anchors self-starting, so no drilling is necessary to install.

Available in both nylon and metal, these anchors work well in drywall, though they do not provide the results achieved with winged and toggle anchors.


When you need the strongest anchor possible for drywall, you can look to toggles for help. They provide the most holding strength out of the options available. There are many different types of toggle wall anchors, including:

  • Traditional
  • Snap
  • Threaded drywall anchor

Designed for use in hollow walls, these toggles have spring-loaded metal wings or a solid bar that spreads the weight of your item across the backside of the wall material. As the toggle element needs room to spread out, these wall anchors cannot be used in solid materials.


Winged anchors function similarly to toggle bolts, but without the bulk and cost. These plastic wall anchors have wings on each side of the mounting point that fold inward for easy installation. Due to the way they are manufactured, these wings hold tight once installed, resisting folding that could allow the anchor to pull out of the wall.
