Hanging Shelves, Hanging Mirrors and Hanging Towel Bars

We’ve chosen five hollow-wall anchors that cover a range of weight requirements, from lightweight knickknack shelves all the way up to heavy-duty utility shelf brackets. Of course, it’s always best to anchor into solid wood if you can, but for those situations where it just isn’t possible, these five anchors will provide superior holding power with the least amount of hassle.

Pictures and mirrors

You can buy special plastic anchors for hanging heavy mirrors and pictures, but you’ll be left with a sizable hole to repair if you decide to relocate the object. The best choice is to do what the pros do. Choose a picture hanger based on the weight of the picture or mirror. The triple nail version we show here holds up to 100 lbs., more than enough for even the heaviest mirrors. But if you’re worried, just use a pair of them spaced about a foot apart for an extra margin of safety. Using picture hangers in pairs like this also prevents the picture or mirror from tipping if it slides on the hanging wire. You’ll find this type of hanger in most full-service hardware stores and home centers or at picture framing shops.

Light-duty shelving

Most lightweight shelves like this one come with expanding plastic anchors, but I wouldn’t rely on them. Instead use these self-drilling, screw-in type anchors. They’re rated to hold about 30 to 50 lbs. each (depending on the size) and take only seconds to install. These anchors (metal or plastic versions) work great for hanging small shelves and other decorative items that aren’t subject to much use and don’t have to support a lot of weight. On a ceiling, don’t use these anchors to hang anything heavier than a smoke detector.

You can screw the anchors in by hand with a No. 2 Phillips screwdriver, but a drill with a No. 2 driver bit works better. Slow the drill to a crawl as soon as the large threads engage in the drywall. Then carefully turn the fastener until the face is almost flush. Overtightening will damage the drywall and compromise the holding power. These same precautions apply to the screw. Turn it in slowly and stop as soon as the screw is snug to the object you’re attaching. Overtightening will strip the threads. If the anchor loosens and spins, you’ll have to back it out and replace it with a toggle-type anchor in the same hole.

Heavy shelves

It’s best to locate a stud or other framing member to mount shelf brackets that support heavy weight. But if you have to mount a shelf bracket on drywall, use these Toggler anchors. They’re easier to use and stronger than standard wing-type toggle bolts. Plus, you can remove the machine screw without losing the toggle inside the wall, which allows you to mount items that may occasionally need to be taken down and reinstalled.

The only drawbacks to Toggler bolts are that they’re a little harder to find and slightly more expensive than standard “molly” bolts. We found ours at a local home center, and they’re also available online. The photos below show how to install Toggler bolts.

Curtain-rod brackets, towel bars and coat hooks

Curtain rod brackets dangling from loose anchors or towel bars pulled out of the wall are all too common. That’s because these jobs require an anchor that can stand up to constant jostling and tugging. And the plastic anchors usually provided just aren’t up to the task. Buy some of these slick, self-drilling metal toggles instead. They’re a little more expensive, but they’re easy to install and hold like crazy. You simply screw them in at the desired locations (Photo1). Then as you tighten the mounting screw, the metal flange flips out and is drawn tight to the backside of the drywall. You can remove the object for painting, and the anchor will remain in the wall, ready for reuse.

The only drawback to these anchors is that you have to use the screw provided or one with the same type of thread. This may mean abandoning the decorative screws included with your hardware. You may have to spray-paint the screwheads to match or search for a decorative screw with the same threads.

Install these toggles just like their smaller cousins. But make sure to probe the wall first to determine if there’s room for the metal flange to flip open. The E-Z Toggle we’re using has arrows on the face to show the alignment of the flange when it opens. This is handy if you have two toggles close together and don’t want the flanges to clash, or to prevent the flange from hitting a stud that’s close to the edge of the toggle. Turn the E-Z Toggle in or out slightly to adjust the orientation of the metal flange.

4 Tips for Choosing Anchors

1. Probe the wall before choosing an anchor. Before you shop for anchors, probe the wall to determine the thickness of the covering, the depth of the cavity and the presence of any obstructions. This simple step will only take a few minutes and can make the difference between a smooth installation and a frustrating experience. Drill a 1/8-in. hole through the drywall or plaster at the anchor locations. Bend a 1-in. long, 90-degree hook on the end of a coat hanger or other stiff wire and slide it through the hole. Twirl it to feel for obstructions. Push it all the way in and make a mark flush to the wall with a marker or tape. Now pull it tight to the backside of the wall covering and make a second mark. Remove the wire and measure from the bend to your marks to determine the thickness of the wall covering and the depth of the cavity. With this information, you can select the best anchor and install it without the risk of hitting a plumbing pipe or electrical cable.

2. Match the anchor to the wall thickness. Check the package to see what type and thickness of wall the anchors work in. For example, some plastic toggles have a grip range of 3/8 in. to 1/2 in. and won’t work on plaster walls that are 3/4 in. thick. Most anchors are available in a number of sizes with different “grip ranges,” so it shouldn’t be hard to locate one that will work.

3. Use the right screw for the anchor.  Some anchors come with sheet metal screws, but you can usually substitute a similar size wood screw or drywall screw. Metal toggles, on the other hand, only accept screws that match their threads. If screws are provided with the anchors, check the package for the “maximum fixture thickness.” If you’re hanging a 3/4-in. thick wood shelf, for example, and the maximum fixture thickness listed is 5/8 in., you’ll have to buy longer screws of the same type. If you want to use the decorative screws that are included with the item you’re installing, then look for an anchor that will work with those screws.

4. Make sure there’s room in the wall. All of the anchors we show here work in standard 2x4 walls, as long as they don’t hit pipes, ducts, wood blocking or other obstructions. But choose your anchor carefully if you’re mounting to exterior basement walls, walls in manufactured homes or other unusual wall types. Metal toggles, for example, require a certain amount of depth and space for the toggle to flip open. You can’t use them in thin walls or walls with rigid foam insulation.

Medium-duty shelves and racks

Most shelf brackets and standards have several mounting holes, so you can rely on the combined strength of many fasteners to support them. But they require an anchor that won’t pull out of the wall when you tighten the screw. Plastic toggles meet both of these requirements. They’re rated to support about 30 to 50 lbs. each and are designed to prevent pullout by hooking the backside of the drywall.     

You have to drill a hole for these anchors. Hold the shelf standard at the right height and use a level to align it vertically (plumb). Mark the hole locations with a sharp pencil. Drill the recommended hole size (3/8 in. for these 5/8-in. Kwik-Tog anchors) at each mark. Then install the anchors as shown in the photos. Some types of plastic toggles require you to “pop” them out after sliding them into the hole. Take care not to overtighten the screws or the plastic will strip and the screw won’t hold.
