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). When users need heavy-duty holding power, they should opt for toggle anchors, which come in a variety of sizes, designs, and materials, including metal and plastic.

May be used in ceiling drywall for lightweight items, such as smoke alarms.

Have a permanently attached shank, but the screw can be removed.

Have a holding power of 25 to 55 pounds, depending on size.

Molly bolts have the following attributes: This makes it handy if DIYers are replacing items such as toilet paper holders in the same spot. When correctly inserted, the screw can be removed from the anchor, which remains securely in the wall, and then reinserted. 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. The underside of the anchor’s head features sharp metal tips that pierce the drywall surface. Here’s how it works: A pilot hole is drilled into the drywall, and then the anchor is inserted into the hole. 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.

Easy to install with a screwdriver or screw gun.

Cost $.25 to $.40 per anchor, depending on brand and size.

Self-drilling no pilot hole necessary.

Holding power of 25 to 75 pounds, depending on size.

Threaded drywall anchors have the following attributes: Metal versions rely on a deeper thread for grip. With nylon versions, this forces the sides of the anchor to flare and wedge the anchor tightly against the drywall. Once the anchor is in the wall, the screw is inserted. They feature sharp, pointed shanks that can be screwed into the wall without a predrilled hole by using a screwdriver or a screw gun.

Not suitable for use on ceiling drywall because downward pressure can cause the anchor to slip out.Īlso called “self-drilling drywall anchors” or “self-tapping anchors,” threaded drywall anchors are made of hard nylon or metal and are able to hold heavier items.

Able to hold between 5 and 25 pounds, depending on brand and size.

Affordable, averaging $.03 to $.20 per anchor, depending on size.

Often made of plastic but may also be made of nylon or zinc-coated metal.

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. 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. The anchor’s shank (tapered end) is split in half. True to their name, expansion anchors spread to create a tight bond with the wall and are designed to hold lightweight items. Ease of installation, strength, and cost each have an impact, and each of these is discussed in the following section. It’s important to understand how each type performs to choose the right one for the job.

That will help the consumer narrow the range of options. Rather than just picking up a random drywall anchor, users need to think carefully about the amount of support needed for the item intended to hang on the wall. 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. 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. Drywall-comprised of compressed gypsum (a soft sulfite mineral)-creates wonderfully smooth walls.
