How to Use Toggle Bolts
Toggle bolts are one of the strongest wall fasteners you can use when mounting heavy items on drywall. Unlike basic plastic anchors that grip only the drywall surface, toggle bolts spread the load behind the wall using spring-loaded wings. That extra support makes them a popular choice for heavier shelves, mirrors, large wall décor, and other mounting jobs where ordinary anchors may not feel strong enough.
For many homeowners, toggle bolts are one of those tools that seem intimidating at first. The wings fold, the hole size is larger, and once the toggle goes behind the wall, you do not get many second chances. But the process is actually simple when you understand the order of steps and choose the right bolt size for the job.
In this guide, you will learn how to use toggle bolts step by step, when they make sense, when they do not, what tools you need, and how to avoid the most common installation mistakes.
Quick Answer
To use toggle bolts, first drill the correct-size hole in the drywall, thread the bolt through the mounting bracket or fixture, attach the spring wings, fold the wings closed, insert them through the wall, then tighten the bolt until the wings pull firmly against the back of the drywall. Toggle bolts are best for heavier wall items when no stud is available in the right position.
See the Best Drywall AnchorsWhat Are Toggle Bolts?
Toggle bolts are heavy-duty hollow-wall fasteners designed for drywall, plaster, and other wall surfaces where no stud is available in the exact location you need. The bolt passes through a pair of spring-loaded metal wings. Once those wings go through the drilled hole, they open behind the wall and spread the load over a larger area.
That is what makes toggle bolts stronger than many lightweight anchors. Instead of relying only on the wall face, they create support behind the wall panel itself.
When Should You Use Toggle Bolts?
- When mounting heavier mirrors
- When installing shelf brackets that do not line up with studs
- When hanging larger wall décor
- When extra holding strength is needed on drywall
- When plastic anchors do not feel strong enough for the load
Toggle bolts are especially helpful when you need stronger drywall support but cannot mount directly into a stud. For general wall mounting strategy, also see our guides on How to Hang Shelves on Drywall and How to Mount a TV on Drywall.
Important: Toggle bolts are strong, but they are not a replacement for studs in every situation. Very heavy or high-stress items, especially full-motion TV mounts or heavily loaded shelves, are often still safer when mounted into studs.
Tools You May Need
- Toggle bolts in the correct size
- Drill and drill bit
- Screwdriver or drill driver
- Tape measure
- Level
- Pencil
- Stud finder if you want to check for framing first
A good power drill, a reliable tape measure, and a stud finder can make this project much easier and more accurate.
Step-by-Step: How to Use Toggle Bolts
-
Check for a stud first.
Before using a toggle bolt, make sure a wall stud is not available where you need to mount the item. Stud mounting is often stronger and simpler if the location works. -
Choose the right toggle bolt size.
Pick a toggle bolt rated for the weight of the item and compatible with the thickness of the fixture or bracket you are mounting. -
Mark the mounting location.
Use a pencil, tape measure, and level if needed. Accurate placement matters because toggle bolt holes are usually larger than standard anchor holes. -
Drill the hole.
Use the drill bit size recommended for the toggle bolt wings. The hole needs to be large enough for the folded wings to pass through the drywall. -
Insert the bolt through the fixture first.
This step matters. Put the bolt through the bracket, mirror mount, or other item before attaching the toggle wings. -
Thread the wings onto the bolt.
Attach the spring-loaded wings so they will fold toward the wall when inserted. -
Fold the wings and push them through the hole.
Compress the wings, guide them through the wall opening, and let them spring open behind the drywall. -
Pull back gently while tightening.
As you tighten the bolt, pull lightly so the wings stay firm against the back of the wall. Tighten until the fixture feels secure. -
Do not overtighten.
Too much pressure can damage the drywall surface or crush the wall material instead of improving strength.
Helpful tip: Once a traditional toggle wing falls behind the wall, you usually cannot remove the bolt and reuse the same toggle without losing the wing inside the wall. That is why correct placement and setup before insertion matter so much.
What Can You Hang with Toggle Bolts?
Toggle bolts are often used for:
- Heavy mirrors
- Wall-mounted shelving brackets
- Larger framed artwork
- Bathroom accessories
- Wall organizers
- Curtain rod brackets when studs do not line up
They are generally a better fit for fixed, heavy wall items than for light decorative pieces that could use smaller anchors more easily.
Toggle Bolts vs Standard Drywall Anchors
Standard drywall anchors are easier to install and usually leave smaller holes, but they are not always ideal for heavier loads. Toggle bolts require a larger hole and a little more planning, but they usually provide stronger support because the wings spread the force behind the wall.

Common Mistakes to Avoid
- Forgetting to put the bolt through the fixture before attaching the wings
- Drilling the wrong hole size
- Using toggle bolts when a stud is available
- Choosing a bolt too short for the wall and fixture thickness
- Overtightening and crushing the drywall
- Using toggle bolts for items that create too much outward leverage
When Not to Use Toggle Bolts
Toggle bolts are strong, but they are not the best answer for every wall job. If the mounted item creates a lot of leverage or movement, such as some articulating TV mounts, or if the item is extremely heavy, studs are usually a safer choice. Toggle bolts also may not be ideal when you expect to remove and remount the item repeatedly.
FAQ
Are toggle bolts stronger than drywall anchors?
In many cases, yes. Toggle bolts are often stronger than lightweight drywall anchors because they spread the load behind the wall.
Can you use toggle bolts in drywall?
Yes. Drywall is one of the most common places people use toggle bolts, especially for heavier wall-mounted items.
Do toggle bolts need a stud?
No. They are specifically useful when a stud is not available where you need the mounting point.
Can toggle bolts hold shelves?
Yes, especially shelf brackets, but the total weight still matters. Very heavy shelving is usually best supported by studs whenever possible.
What is the main downside of toggle bolts?
They require a larger hole, take more setup than basic anchors, and traditional versions are less convenient to reposition once installed.
Final Verdict
Learning how to use toggle bolts is one of the most useful wall-mounting skills a homeowner can have. They are strong, practical, and often the best option when you need more holding power on drywall but do not have a stud in the right spot.
The key is choosing the right size, drilling the correct hole, and tightening carefully without rushing the setup. If you regularly mount shelves, mirrors, or heavier wall décor, toggle bolts can become one of the most reliable fasteners in your DIY toolbox.
