Drywall—comprised of compressed gypsum (a soft sulfite mineral)—creates wonderfully smooth walls. Yet insert a nail or screw into it and it’s likely to crumble, often resulting in the fastener working loose and the hung item falling to the floor. The solution is to use drywall anchors, which are designed to spread within or behind the drywall panel, creating pressure that locks the anchor in place.
Before you pick up any old drywall anchor, think carefully about the amount of support you need for the item you intend to hang on the wall. That will help you narrow the varied range of options. For this type of hardware, there are four main types, largely distinguished by the weight they are capable of holding. To understand more about each type—and to see our top recommendations—keep reading.

Know the Holding Power You Need
Drywall anchors come in various designs, sizes, and holding power (maximum weight of an object you can safely hang). While manufacturers are not required to list their anchors’ holding power, many do, either on the package or in the included literature. Additionally, basic drywall anchor types are associated with a range of holding power (see individual anchor descriptions below). Always use an anchor with a holding power that meets or exceeds the weight of the item you want to hang.
Selecting the Right Size for Screws and Drill Bits
Drywall anchors can be purchased separately from the screws they hold in place, but it’s wise to buy anchors that come packaged with the correct size screws if you don’t have a wide variety of screws handy. If you prefer to purchase the anchors and screws separately, you’ll find the required screw size on the package. If the type of anchor you select requires a pre-drilled pilot hole, you will also find the corresponding drill bit size on the package.
Understanding the Types of Drywall Anchors
1. EXPANSION DRYWALL ANCHORS
True to their name, expansion anchors spread to create a tight bond with the wall and are designed to hold lightweight items. The anchor’s shank (tapered end) is split in half. To install, a pilot hole is drilled in the wall, the anchor is fitted into the hole, and then a hammer is used to lightly tap the anchor head flush with the wall. When a screw is inserted into the anchor, the split ends of the shank spread, expanding and putting pressure on the inside of the drywall to hold it securely.
Expansion anchors are:
- Often made of plastic but may also be made of nylon or zinc-coated metal.
- Affordable, averaging $.03 to $.20 per anchor, depending on size.
- Easy to install and DIY friendly.
- Able to hold between five and 25 pounds, depending on brand and size (larger anchors hold more weight).
- Not suitable for use on ceiling drywall as downward pressure could cause the anchor to slip out.
2. THREADED DRYWALL ANCHORS
Also called “self-drilling” or “self-tapping” anchors, threaded drywall anchors are made from hard nylon or metal and are able to hold heavier items. They feature sharp, pointed shanks that can be screwed into the wall without a pre-drilled hole by using a screwdriver or a screw gun. Once the anchor is in the wall, the screw is inserted, which forces the sides of the anchor to flare and wedge the anchor tightly against the drywall.
They have the following attributes:
- Holding power of 25 to 75 pounds, depending on size.
- Self-drilling; no pilot hole necessary.
- Cost $.25 to $.40 per anchor, depending on brand and size.
- Easy to install with screwdriver or screw gun.
- Not suitable for use on ceilings.
3. MOLLY BOLTS
Known as “molly bolts” or simply “mollies,” these metal sleeve-type hollow wall anchors provide medium-weight holding power, but offer a unique feature—the ability to remove the screw and reinsert it if necessary in the future.
Here’s how it works: A pilot hole is drilled into the drywall and then the anchor is inserted into the hole. The underside of the anchor’s head features sharp metal tips that pierce the drywall surface. When the screw is inserted in the anchor, each twist of the screw forces the shank of the anchor to compress (lengthwise) while it expands sideways. When correctly inserted, the screw can be removed from the anchor, which remains securely in the wall and then reinserted. This makes it handy if you’re replacing items in the same spot—such as toilet paper holders.
- Have a holding power of 25 to 55 pounds., depending on size.
- Require a pre-drilled hole.
- Have a permanently attached shank, but the screw can be removed.
- May be used in ceiling drywall for lightweight items, such as smoke alarms.
- Cost $.25 to $.40 per anchor, depending on brand and size.
4. TOGGLE BOLTS
When you need serious holding power, opt for toggle anchors, which come in a variety of sizes, designs, and materials, including metal and plastic.
Traditional metal toggle bolts are the strongest of the bunch, but they’re not the simplest to install because they require drilling a hole that’s approximately three times wider than the diameter of the bolt (necessary to insert the anchor). With these, the anchor features one or two bars (or wings) that fold flat against the bolt during insertion. Once inserted, a quick twist of the bolt loosens the wings, causing them to flare outward. As the bolt is tightened with a screwdriver, the wings draw inward to form a strong perpendicular brace along the backside of the drywall. The installation challenge comes in keeping the bolt centered in the hole while tightening it. It takes some practice and patience to get it right, but once you do you’ll be impressed by the strong holding power. It’s more likely that the wall itself will fail before the toggle bolt does.
Winged plastic anchors (the new kids on the block) feature plastic “wings” that fold tightly together so the anchor can be inserted into a pre-drilled hole. Once the anchor is in place, a wand (included with the anchor) is pushed through the hole to expand the wings on the backside. A screw is then inserted, which draws the wings snugly against the back of the drywall.
Toggle bolts at a glance:
- Maximum holding power for metal toggles is 100 pounds, depending on size; plastic wing toggles have a holding power up to 20 pounds, depending on size.
- Both metal and plastic toggles can be used on ceilings at 1/3 the holding power listed for walls, up to a maximum of 15 pounds. Drywall may pull away from ceiling joists at heavier weights.
- Metal toggles can be difficult to keep level in the wall during installation.
