Toggle bolts are the strongest way to anchor heavy items to hollow walls. Learn how to install toggle bolts correctly and easily.
When you are installing anything on drywall, you need to find studs to screw into. The drywall by itself is too soft and crumbly to hold a screw.
What if you don’t have a stud in the spot you need? That is where drywall anchors come in, and toggle bolts are the strongest anchors there are. They are the best choice for hanging heavy items on hollow walls.
Once you learn how to install one and see how strong they are, you will never go back to using the cheap plastic anchors.

What are toggle bolts?
Toggle bolts are heavy-duty anchors perfect for installing anything in the drywall where you cannot find and screw into studs. They consist of two parts –
- The bolt – the length and diameter of these decide their strength
- The toggle – The butterfly-shaped nut whose size also determines the strength.
How do toggle bolts work
The butterfly toggle is pinched and inserted into the hollow drywall, where it opens up. As the bolt is tightened, it presses against the drywall. This causes the bolt to anchor in the drywall. The larger the area of the butterfly toggle in contact with the drywall, the stronger the anchor and higher the weight rating.
What size toggle bolts do I need?
Toggle bolts are available in many sizes. To pick the right-sized toggle bolt, you have to consider both the application and your wall type.
- The first thing to consider is the thickness of your wall. ⅜” and ½” are the most common drywall thicknesses. The toggle bolts should be long enough so that when you fold and push the toggle into the wall, there should be enough clearance for it to open up behind the wall.
- Next, it the weight rating. If you need a heavy-duty toggle bolt, you will need to get one with a larger surface area on the butterfly nut.
I am installing a DIY floating shelf in the example below and using a 4″ x ¼” toggle bolt. The 4″ long bolt is because it needs to pass through the 1½” thick board and then through the drywall. ¼” is the diameter of the bolt. Since these shelves will be holding dishes etc., in my kitchen, I went with the highest weight rating I could find.
If you are hanging something like a coat hook, you will likely not need such a long bolt, and the bolt diameter will depend on the hole in the hook.
Material needed for installation
- Drill bits – ⅛” and a larger bit depending on your toggle bolt size.
- Toggle bolts of choice. Here is an option to use
- Drill/ Driver
How to install toggle bolts
When you first look at a toggle bolt, it may seem intimidating, but, in fact, it is straightforward to install!
Step 1 – Identify location
You must identify the exact location for the toggle bolt and verify that there is no electrical or plumbing running behind it.
Step 2 – Make the holes
- Once you have identified the toggle bolt’s location, use the ⅛” drill bit to make a starter hole at that location.
- Use the larger drill bit to make a hole in the wall. This bit should be the size of the butterfly nut when folded. In my case, it was ½.”
Step 3 – Thread the toggle bolts
- Insert the bolt into the item you would like to attach.
- Screw in the butterfly toggles on the other side of the item. Pay attention to the direction the toggles face.
Step 4 – Insert into the wall
- Pinch the butterfly wings together.
- Push the entire toggle nut into the large hole in the wall.
- Once inside, you should hear it open.
Step 5 – Tighten
Using a screwdriver or a power driver, tighten the bolt from the front.
Important – The butterfly toggle should be resting on the drywall on the inside for the bolt to tighten. If not, the bolt will spin and will not tighten. This is a very common problem people encounter with toggle bolts. It has a straightforward fix. Just pull the bolt outward to rest the toggle on the drywall and start tightening. As it tightens, the bolt will pull the item towards the wall and form a strong anchor.
What can toggle bolts be used for?
You can literally use toggle bolts anywhere you need to attach something heavy to a hollow wall – think coat hooks, shelves, large paintings. They are basically the perfect anchor to use and install. They are also super easy to install and much stronger than other plastic options. They are especially great when hanging items from the ceiling.
How to remove a toggle bolt from the wall
Uninstalling toggle bolts are easier than installing them! You simply unscrew the bolt from the front with a screwdriver. The only drawback is – the toggle or the butterfly wing will fall off inside behind the drywall and cannot be recovered. You will need to purchase new toggle nuts if you want to reuse the bolt.
