ᐅ How can I securely mount Billy shelves on drywall (gypsum board) walls?

Bidi35Hello everyone, I am planning to mount several Ikea Billy shelves on a drywall partition and want to do this as securely and permanently as possible. The wall is made of gypsum plasterboard with a metal stud framework – no wooden studs. My question is: What type of anchors or fasteners are best suited for hanging heavy shelves like the Billy, so that the load is well distributed and nothing pulls out? Are there any special installation methods I should follow to ensure the shelves not only hold but remain stable in the long term? I would appreciate any advice on the procedure, suitable screws, and anchors, especially considering the specific characteristics of drywall. Thanks!
Hello Bidi35,
First of all, I find your question very precise, which makes it much easier to provide advice. When dealing with drywall (plasterboard) walls mounted on metal studs, it is indeed important to choose the right type of fastener.
1. Anchor type: For heavy loads, metal expansion anchors or hollow wall metal anchors (e.g., toggle anchors) are suitable. These expand behind the drywall and provide a secure hold.
2. Alternatively, you can screw directly into the metal studs – for this, you need to locate the stud positions using a metal detector.
3. Multiple fastening points distribute the load better, so use at least 4 screws per shelf, preferably more if the shelf width allows.
Tip: Avoid regular plastic anchors for heavy shelves, as they are often only suitable for light loads.
If you want, I can write you a short guide on how to proceed with the installation.

Metal toggle anchors or hollow wall metal anchors (e.g., snap toggles). They expand behind the drywall and provide a strong hold.Thanks for the tip! So are these metal anchors better than the so-called drywall anchors made of plastic? I just want to avoid the shelf falling off the wall after some time.

What do you think, is that the safest method? Or are the hollow wall metal anchors really secure enough?
On the different fastening methods for drywall and metal framing:
The most secure way to mount a heavily loaded shelf like a Billy is actually to screw directly into the metal studs of the wall. The drywall itself does not support the load permanently but only serves as a covering.
Hollow cavity metal anchors are mechanically suitable for medium loads (maximum 10-15 kg (22-33 lbs) per anchor). Since Billy shelves often weigh around 30-50 kg (66-110 lbs) in total, several of these anchors should be used, or the screws should be anchored into a more stable substrate.
The best solution is therefore:
- Precisely determine the location of the studs (preferably with a metal detector)
- Pre-drill there using special drill bits
- Screw directly into the metal stud (self-tapping sheet metal screws)
If this is not possible, hollow cavity metal anchors can be used to distribute the load. However, this increases the requirements for the number and placement of the anchors.

The best solution is: accurately determine the profile layout (ideally with a metal detector)
- Pre-drill at those points using special drill bits
- Screw directly into the metal profile (self-tapping sheet metal screws)Understood, thanks for the explanation. Do you have any tips on the ideal screw length? I don’t want the screw to go all the way through, but it should of course be long enough to securely reach and hold the profile.
And one more detail question: Is there anything I should keep in mind when drilling or screwing to avoid damaging the drywall sheet when working directly on the profile?
