Hello everyone, I want to assemble a few Billy shelves and am unsure which fastening techniques are most recommended. IKEA provides screws and wall plugs, but I wonder if it might be more effective to use additional methods or different types of screws to improve stability or to make assembly easier and more durable. I am especially interested in techniques that have proven effective when installing multiple shelves side by side or in corners. Are there any tips for pre-drilling, gluing, or specific screw types that should be preferred? I’m also curious about the required torque and whether a cordless drill or manual tools are better to use. I would appreciate all experiences and recommendations!
An addition on screw technology for Billy shelves:
The screw penetration depth should definitely reach into the core of the particleboard, not just the surface layer.
To prevent the surface from splitting, as mentioned several times before, pre-drilling is essential.
Regarding torque, I recommend a maximum of 10-12 Nm to avoid damaging the wood—especially with softer particleboard.
I suggest using countersunk screws, which also look better if you want to fill or cover them later.
And very important: to prevent tipping and twisting, fasten not only to the alignment wall but also connect the shelves to each other with additional brackets.

I agree with the previous recommendations and would like to add a small tip:
When pre-drilling, you can also countersink the holes slightly so that the screw heads sit flush. This not only looks better but also prevents splintering when tightening.
For assembly with a cordless drill, I recommend using a bit with a magnet – it saves frustration because the screws hold better.
Good luck with the build! 🙂

A brief addition to the tips mentioned so far:
When joining multiple shelves, it is advisable to use a combination of screws and dowels to better withstand lateral forces.
Dowels should be accurately recessed and glued in place. This significantly increases the structural stability of the assembly. This is especially important if you plan to frequently rearrange the shelves or if they will bear heavy loads.
Additionally, use screws with a fine thread because coarse threads can cause particleboard to swell.

Are there any special screws or fastening systems you would recommend?I personally often use cam lock connectors, similar to those used in flat-pack furniture. They are a bit more complex to install but provide a very tight and stable connection, especially if you want to disassemble the shelves later.
Additionally, they allow you to precisely adjust the distance between the shelves.
For BILLY shelves, I also like to use extra battens on the back panel to reduce lateral tilting. Screws alone are often not enough here.
Are there any specific challenges with your wall, for example drywall, that might restrict certain types of fastenings?
