ᐅ How do I mount BILLY shelves on drywall (gypsum board)?

The wooden batten is good, but don’t forget that the batten must be securely fixed at 3-4 points using strong anchors.

Exactly, and preferably to the metal studs behind it, if possible.

Correct. For example, there are cavity anchors with multiple flaps or expanding arms that press against the back side over a wider area. These provide better hold than simple toggle anchors. However, the correct drill hole size and positioning are crucial.

If you like, I can give you the model numbers. Otherwise, feel free to ask if you have more questions.

Yes, please! I want to do it as professionally as possible and make sure there’s no chance of shelves wobbling. I also like the alternative solution with the wooden batten, but I’ll first try directly with anchors. Thank you very much for the detailed information!

Sure. The most popular heavy-duty anchors for drywall that I can recommend are, for example:

1. Fischer UX or its heavy-duty version SXR with a metal expansion arm.

2. TOX metal cavity anchors that expand at the back to provide a secure hold.

3. Spax metal cavity anchors, specially designed for wood and drywall walls, capable of carrying high loads.

These anchors usually include installation instructions on the packaging. It is important that the drill hole is made precisely and that the anchor fully expands before the screw is completely tightened.

If you hit the metal stud while drilling, the screw must be fastened into the stud frame; otherwise, the anchor effect will be minimal.

If you want, I can also give you tips on how to locate the stud in drywall.

Thanks, Palenar! Locating the stud frame sounds important. I was thinking of using a simple electronic stud finder – do you have any experience with whether these devices are reliable enough to accurately detect metal profiles behind drywall?

I’d prefer to avoid causing significant damage with oversized holes. Also, is it worth investing in a professional-grade detector, or are the simpler models sufficient?

Yes, inexpensive devices generally work quite well if you move them slowly along the wall. Metal studs and electrical wiring are usually easy to detect.

Important when buying: make sure the device has a depth detection of at least 12–15 mm (0.5–0.6 inches) so that metal studs behind 12.5 mm (0.5 inches) drywall can be safely found. Some cheaper models tend to give too many false signals, so it’s better to choose devices with good reviews.

Professional devices cost more, but they are worth it if you use them frequently for trade work. For your project, a decent hobbyist finder should be sufficient.

A small tip: if you locate several metal studs, mark their edges on the wall with a pencil to determine the center for screwing.
