Drywall Anchors: Secrets Revealed!
Whether you’re hanging a picture or mounting a television, anything that goes on your wall needs something to anchor it in place. If there’s a stud in the wall that you can attach it to then you’re fine; you’ve got well-supported wood to drive a screw into which will hold whatever you’re mounting in place. If you can’t find a stud where you need one, though, you could have a problem. That’s where drywall anchors come in.
What is a Drywall Anchor?
Anchors are designed to provide a tight fit for your screws. As the screw goes in, the anchor is forced to spread out and open up a bit. This pushes the body of the anchor against the sides of the hole you put it in, causing those little fins to dig into the surrounding drywall. The fins are positioned to go in easy but resist coming out, giving you a solid mounting even though there isn’t any wood or other solid material for your screws to secure to.
If you have a relatively light load, you’ll probably need a plastic anchor. The most common of these are known as expansion anchors and are essentially plastic sleeves that you hammer into a drilled hole and that simply spread out as you insert a screw. There are also threaded plastic anchors that look like oversized screws; they work similarly, except you screw them into place instead of hammering them. Regardless of the type of plastic anchor you use, the purpose is still to dig into the drywall and hold a screw in place.
If you have an even heavier load, you’ll need to use a toggle bolt instead. These anchors consist of a metal bolt with foldable metal wings that the bolt screws into. You have to fold the wings so that they lie over the bolt, then insert them into a hole large enough that they can fit through to the other side. Once on the other side the wings will expand, preventing the bolt from coming back out. Make sure that there is a washer or something else that’s large enough to cover the hole, though, or the bolt head could slip through the hole and you’ll lose your toggle bolt into the wall.
