| A time saving special crimping tool is available if multiple anchors are being fitted part number HWAG on this website) Drill a 7-8 mm diameter hole into the gyprock sheet, remove the screw from the anchor body, and tap the fixing in with a hammer. Fixing must be a good secure tight fit so the fixing body does not spin when tightening the screw. Insert the screw and tighten using a hand held screwdriver (not a power-driver) to collapse (set, crimp) the fixing behind the gyprock sheet. When fully tightened the screw is removed and the shelf bracket, is then attached with the screw into the crimped fixing(s). Note when using these fixings, weight capacity of the shelf or bracket is limited to the actual strength of the gyprock or drywall sheet. Using multiple fixings will increase the weight capacity of the shelf or shelf brackets. See you tube video showing fitting hollow wall anchors here. Show
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. 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. That will help the consumer narrow the range of options. For this type of hardware, there are four main types, largely distinguished by the weight they are capable of holding. Read on to understand more about each type and to see our top recommendations.
Types of Drywall AnchorsThere are four main types of drywall anchors (also called hollow wall anchors), and each has its pros and cons. It’s important to understand how each type performs to choose the right one for the job. Ease of installation, strength, and cost each have an impact, and each of these is discussed in the following section. Expansion Drywall AnchorsTrue 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:
Threaded Drywall AnchorsAlso 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. They feature sharp, pointed shanks that can be screwed into the wall without a predrilled hole by using a screwdriver or a screw gun. Once the anchor is in the wall, the screw is inserted. With nylon versions, this forces the sides of the anchor to flare and wedge the anchor tightly against the drywall. Metal versions rely on a deeper thread for grip. Threaded drywall anchors have the following attributes:
Molly BoltsKnown 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 DIYers are replacing items such as toilet paper holders in the same spot. Molly bolts have the following attributes:
Toggle BoltsWhen 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. 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 back side 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 users do, they’ll be impressed by the strong holding power. There’s more likelihood of the wall itself failing 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 predrilled 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 have the following attributes:
Weight LimitDrywall anchors come in various designs, sizes, and holding power (maximum weight of an object to safely hang). Although 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 to be hung. Screw and Bit SizeDrywall anchors can be purchased separately from the screws they hold in place, but it’s wise for consumers to buy anchors that come packaged with the screws that are the correct size if they don’t have a variety of screws handy. If purchasing anchors and screws separately is preferred, DIYers can find the required screw size on the package. If the type of anchor selected requires a predrilled pilot hole (sometimes recommended with self-drilling drywall anchors), the corresponding drill-bit size is often listed on the package. Our Top PicksOur top drywall anchor picks consistently excel in home use and are favorites among DIYers. Unless noted differently, holding powers listed are for standard, 1/2” thick drywall. Best Overall1 Unvert Self-Drilling Toggle Anchors Photo: amazon.com SEE IT Unvert offers an interesting hybrid that combines the easy installation of self-drilling anchors with the strength of toggle-bolt drywall anchors. The strong metal body cuts through the drywall without the need for a predrilled hole, then the toggle drops and is secured with the Phillips-head screw that is included. Somewhat confusingly, the manufacturer gives weight-rating figures of both 85 and 100 pounds. Either way, that’s a lot of holding power from a self-drilling anchor. The pack includes 25 anchors and screws. Because of the zinc plating, they are highly resistant to rust and would make an ideal choice when moisture-resistant drywall has been used. Product Specs

How We Chose the Best Drywall AnchorsHaving carried out extensive remodels on two homes, we’ve used each of the drywall anchor types myself. One of us is an engineer by profession, so we understand the materials and physical properties. To ensure our information was up to date, the Bob Vila team also researched a wide range of manufacturers and suppliers. When choosing the best drywall anchor options for this article, we wanted to include as wide a variety as possible while still offering appropriate performance. Each of the top picks showcases a particular aspect of these devices, giving drywall-anchor buyers an overall view of the market as well as solutions to specific tasks. None of these fixings are particularly expensive, but price is always a consideration. We were careful to look for good value, but we avoided very cheap drywall anchors that tend to break easily, can damage the drywall during insertion, or may not provide a reliable attachment. FAQsThere is a lot of useful information in the article above to help consumers choose the best drywall anchors for a variety of different tasks. That said, during our research, we did come across a number of general questions that cropped up frequently. For convenience we have covered those here. Q: How are drywall anchors installed?How someone installs drywall anchors depends on the type. The easiest to use are known as self-drilling because they create their own hole. Others need a hole to be drilled. The drill bit for this may be provided with the fixings, but it’s not always the case. Q: How much weight can drywall anchors hold?The weight a drywall anchor can hold varies enormously. Lightweight plastic drywall anchors can support 10 or 15 pounds, whereas the strongest bolts can support more than 200 pounds. However, it is generally recommended that only a quarter of the maximum weight is used per anchor. Often two or more drywall anchors are used (for shelves, for example) so DIYers will want to do a little math to find a fixing with the appropriate capacity. Q: Can drywall anchors be hammered in?No. DIYers would either create too large a hole, thus ruining the grip, or would break the drywall. Users can give self-drilling types a light tap with a wooden or rubber mallet to get the point embedded up to where the thread starts. They can also tap in expansion-type drywall anchors, but only after the correctly sized hole has been drilled. Can drywall anchors hold 40 pounds?Hollow Door and Drywall Anchors (2-Pack) are ideal for use in hollow core doors and drywall. These zinc die-cast anchors offer a holding strength of up to 40 lbs. No pre-drilling necessary in drywall. E-Z Ancor Hollow Door Anchors drill anywhere in hollow core doors and drywall, even if you hit a wood stud.
Can drywall anchors hold 50 lbs?No pre-drilling required - screw directly into drywall. E-Z Ancor Twist-N-Lock 50 Drywall Anchors support 50 lbs. when installed in 1/2 in. drywall.
How much weight can 2 wall anchors hold?anchors on different walls can each support 50lbs, whether or not the load(s) supported is shared between the two or not. However, any holes in the drywall weaken it slightly, so while an anchor in drywall may be rated for 50lbs, putting two within a few inches of each other will decrease this rating.
Are metal anchors Good for drywall?Metal anchors: Also known as hollow wall anchors or molly bolts, metal anchors were the first drywall anchor bolt designs with the ability to hold up to fifty pounds of weight. Use this heavy-duty anchor type over plastic or sleeve anchors to hold large mirrors, heavy frames, and floating bookshelves.
