SarkauHello everyone, I am planning to install several Billy shelves on drywall in my apartment. I want to make sure the shelves are securely mounted and can easily support the weight of fully loaded bookshelves without the screws pulling out of the drywall.
My questions are: What fastening materials and techniques are best for safely attaching Billy shelves to drywall? Should I use anchors or special cavity anchors? Are there any recommendations regarding screw size, placement, and load distribution? Tips on preparation, such as locating studs behind the drywall or whether to use additional measures like a backing plate, would also be very helpful.
I look forward to your practical experiences and suggestions.

Hello Sarkau, I understand your concerns well. Drywall is not as strong as solid walls, so choosing the right anchors is crucial.
Hollow wall anchors that expand behind the panel or toggle bolts that open up and distribute the load are the most common methods. It is also important to create as many fastening points as possible, for example, four screws per shelf.
Furthermore, if possible, you should transfer part of the load to the studs behind the drywall. You can use a stud finder to locate the wooden beams behind the drywall and at least attach the top rails of the shelves directly to them.
If the wall is really weak, sometimes a backing board helps – a sturdy plank that you attach over a large area with appropriate anchors, and then mount the shelf on it. This way, the load is better distributed.

Here is a brief overview with tips for securely mounting Billy shelves on drywall:
1. Choice of materials: Depending on the load, specialized metal hollow wall anchors or toggle bolts are better than plastic anchors. Metal provides more stability for heavy loads.
2. Locating the framework: Use a stud finder to locate wooden or metal studs behind the drywall. Screwing directly into these studs offers the most secure support.
3. Number of attachment points: At least four screws per shelf ensure even load distribution. Be sure to screw into the studs on the upper shelves.
4. Screw and anchor length: Screws should be long enough to securely grip the framework. Anchors must match the wall thickness (usually 12.5 mm (½ inch) drywall).
5. Additional measures: For heavy loads, installing a backing plate can help. This involves securely attaching a wooden board to the wall, onto which the shelf is then fastened.
Avoid mounting shelves using only short anchors in the drywall; the load could cause localized damage.

Screws directly into these are the most stable.Exactly, it’s much more secure when you screw into the studs. Otherwise, always use hollow wall anchors.
I would like to emphasize the load limits: Drywall alone is not strong enough to support fully loaded Billy shelves. Even with cavity anchors, you should not put too much weight on each individual anchor.
A load of about 10-15 kg (22-33 lbs) per anchor is an approximate guideline. That is why multiple anchoring points are necessary.
Furthermore, the screw length should be chosen so that it penetrates several centimeters into the stud, meaning into the wood or metal profile. Screwing only into the drywall without a proper anchor provides almost no stability.
In conclusion: Supporting the shelves from below against the wall or using a floor support can help reduce the load.
