How to Select the Right Toggle Bolts for Drywall

If you’re planning to hang heavy objects on your drywall, such as shelves, one effective way to achieve this is by using toggle bolts. Toggle bolts are reliable fasteners that provide extra stability and support for heavy loads. In this article, we will guide you through the process of selecting the right toggle bolts for your drywall, ensuring a safe and secure installation.

Before we delve into the details of selecting the right toggle bolts, let’s first understand what toggle bolts are and how they work.

Toggle bolts, also known as butterfly anchors, are specialized fasteners designed for use with drywall. They consist of two main components: the toggle and the bolt. The toggle is a spring-loaded mechanism that folds flat to fit through a pre-drilled hole in the drywall.

Once the toggle is on the other side of the drywall, it springs open, providing a sturdy anchor point. The bolt is then inserted into the toggle, securing the item you wish to hang.

Toggle bolts are particularly useful when there is no stud or other solid support behind the drywall. They distribute the weight of the object across a larger area, reducing the risk of damage to the drywall.

Selecting the appropriate toggle bolts for your drywall is essential for a successful installation. Here are the key factors to consider:

1. Weight Capacity

The weight capacity of a toggle bolt refers to the maximum load it can support. It is crucial to choose a toggle bolt that can handle the weight of the object you plan to hang. 

Exceeding the weight capacity can lead to the bolt pulling out of the wall, causing damage or failure.

To determine the weight capacity, check the packaging or product specifications provided by the manufacturer. The weight capacity should be clearly stated, allowing you to match it with the weight of your object. 

It’s always a good idea to choose a toggle bolt with a weight capacity that exceeds the actual weight of the object for an extra margin of safety.

2. Bolt Size and Length

The size and length of the bolt play a significant role in the stability and security of the installation. The bolt should be long enough to pass through the object you are hanging, the drywall, and have enough length to accommodate the toggle.

To determine the appropriate bolt size and length, follow these steps:

  • Measure the thickness of the drywall.
  • Add the thickness of the object you are hanging to the measurement from step 1.
  • Ensure that the bolt length is greater than the combined thickness from step 2.
  • Using a bolt that is too short may not provide enough engagement with the toggle, compromising the strength of the anchor.

3. Hole Size

The size of the hole you drill in the drywall is crucial for proper toggle bolt installation. The hole should be large enough to allow the folded toggle to pass through but not excessively big, as it can reduce the holding strength of the anchor.

Typically, the hole size required will be provided by the toggle bolt manufacturer and will depend on the specific toggle bolt size you are using. It’s important to follow the manufacturer’s guidelines to ensure a secure installation.

4. Material and Finish

Toggle bolts are available in various materials and finishes, each suited for different applications. The material and finish can affect the bolt’s strength, durability, and resistance to corrosion.

Common materials used for toggle bolts include steel, zinc-plated steel, and stainless steel. Steel toggle bolts are generally strong and reliable, while zinc-plated and stainless steel options offer increased corrosion resistance.

Consider the environment in which the toggle bolts will be used. For example, if you plan to install them in a bathroom or other moisture-prone areas, opting for stainless steel toggle bolts can help prevent rust and corrosion.

5. Installation Process

When selecting toggle bolts for drywall, it’s important to consider the ease of installation. Some toggle bolts require manual tightening, while others are designed for use with power tools. Choose toggle bolts that align with your comfort level and the tools you have available.

Additionally, consider if the toggle bolts come with installation instructions or video tutorials. Clear instructions can make the installation process smoother, especially for beginners.


Selecting the right toggle bolts for your drywall is crucial to ensure the safety and stability of your installations. 

By considering factors such as weight capacity, bolt size and length, hole size, material and finish, and the installation process, you can confidently choose the appropriate toggle bolts for your specific needs.
