/diy/ - Do It Yourself

It's called a spring toggle, and the screw has to be through the thing you're planning to fix and through the spring toggle before you put it in the wall. You only get one shot at this, because when you take the screw out, the toggle falls into the wall forever. So put all your spring toggles together, and drill all your holes, and make sure everything lines up and double-check everything before pushing in. Wouldn't hurt to push a drill bit or pen down each hole to make sure there's enough room for the toggle to go all the way in and open.

Frankly, these things do work, but they need quite a bit of cavity to go into, and they can be a bit fiddly. Consider using a "wall anchor" instead: you're supposed to use a tool but so long as you get a reputable brand you can just put a nut and two washers between the anchor and the screw, and screw them in with a screwdriver until the screw won't go any further. Then unscrew and you have a permanent, reusable machine screw hole in your wall. Pay attention to the thickness specification when you buy them, they clamp both sides of the wall, so the wall thickness needs to be what they're designed for.
