When you’re hanging something heavy on your wall like a shelf, mirror, or even a large frame you need more than just a regular nail or screw. That’s where drywall anchors come in. Drywall isn’t strong enough on its own to support weight, especially if there’s no stud behind it. Using drywall anchors helps distribute the weight and keeps your items securely mounted without damaging your walls.
In this guide, you’ll learn everything you need to know about using drywall anchors the right way. Whether you’re a beginner or someone doing regular home upgrades, you’ll walk away confident and ready to tackle your next wall-hanging project.
What Are Drywall Anchors?
Drywall anchors are small plastic, metal, or nylon inserts that grip the drywall and hold screws in place. They act like a middleman between the screw and your wall, giving the screw something solid to grab onto. This added support keeps the screw from tearing out of the wall under pressure.
There are many types of drywall anchors like toggle bolts, expansion anchors, self-drilling anchors, and molly bolts. The kind you use depends on the weight of the item and the condition of your wall. Some are better for lightweight decorations, while others are designed for heavy-duty use.
When Do You Need a Drywall Anchor?
If you’re not drilling directly into a wall stud, you’ll usually need a drywall anchor. A stud is a wooden beam behind your drywall that provides solid support for screws. But studs aren’t always where you need them. If you’re mounting something and a stud isn’t there, a drywall anchor is your best bet.
You should use drywall anchors when hanging:
- Shelves
- Curtain rods
- TVs (lighter models)
- Mirrors
- Cabinets
- Wall-mounted lights
For anything over 30 pounds, you’ll want to use heavy-duty anchors or find a stud instead.
Tools You’ll Need
Before you start, gather the right tools. Here’s what you’ll typically need:
- Drill (or screwdriver)
- Hammer (optional, depending on anchor type)
- Pencil
- Wall anchor kit
- Stud finder (optional, but helpful)
Guide to How to Use Drywall Anchors
Let’s walk through the process of installing drywall anchors safely and properly.
1. Mark the Spot
Use a pencil to mark where you want the screw to go. Make sure it’s level, especially if you’re hanging multiple objects side-by-side.
2. Check for Studs
Use a stud finder to scan the wall. If you hit a stud, you may not need a drywall anchor. If there’s no stud, proceed with the anchor.
3. Choose the Right Anchor
Pick the anchor based on the weight of the item. Use light-duty plastic anchors for items under 10 pounds. For anything heavier, use toggle or molly bolts. Always check the packaging for weight limits.
4. Drill a Hole (if needed)
Some anchors require you to pre-drill a hole. For example, expansion anchors and molly bolts need a pilot hole. Use a drill bit slightly smaller than the anchor’s diameter.
5. Insert the Anchor
Push or tap the anchor into the hole. If it doesn’t go in easily, gently tap it with a hammer until it’s flush with the wall.
For self-drilling anchors, you don’t need a hole—just screw them directly into the drywall using a screwdriver.
6. Insert the Screw
Now screw in the screw provided with the anchor. As you tighten it, the anchor expands inside the wall, gripping firmly in place. Don’t overtighten, or you might strip the anchor.
7. Hang Your Item
Once the anchor and screw are securely in place, hang your item. Gently pull it to make sure everything feels solid.

FAQs About How to Use Drywall Anchors
Can I reuse a drywall anchor?
It depends on the type. Plastic anchors usually can’t be reused. Metal ones like toggle bolts may be, but only if they didn’t bend or break during removal.
How much weight can a drywall anchor hold?
Light plastic anchors can handle up to 20 pounds. Toggle bolts and molly bolts can support between 50–100 pounds, depending on the wall type and anchor size.
What happens if I install an anchor incorrectly?
Remove it and patch the hole with wall filler or spackle. Once dry, sand it smooth and try again nearby.
Can I use drywall anchors in the ceiling?
Yes—but only with special anchors rated for ceiling use. Don’t hang heavy items from the ceiling without using toggle bolts or screwing directly into a joist.
Do I need drywall anchors for every wall type?
No. For solid walls like brick, concrete, or wood, you’ll need masonry anchors or just screws, depending on the material.
Pro Tip for How to use Drywall Anchors
Not all drywall anchors are created equal. It’s worth spending a bit more for reliable brands that offer better grip and weight ratings. Quality hardware ensures safety and peace of mind, especially when mounting valuable or heavy items.
Using drywall anchors correctly is an easy and affordable way to hang things securely without damaging your walls. Whether you’re redecorating a room or adding a few shelves, the right anchors give you confidence and flexibility. Remember to choose the right anchor for the job, follow the installation steps, and check weight ratings before hanging anything.
