Hello everyone,
I am currently working on assembling the Ikea Platsa system and am wondering which screws are best to securely and permanently connect the modules.
I am aware that Ikea already includes specific connecting screws, but I am concerned that these may not provide the most stable support, especially if you want to expand the system flexibly or move it frequently.
I am looking for screws that are ideally suited in terms of material thickness, length, and thread type for the existing holes and the wood-based material (particleboard with veneer).
Does anyone know of alternative screws that are particularly recommended for the Platsa system? What are the advantages and disadvantages of using standard wood screws, machine screws, or possibly specialty screws?
Thank you in advance for your experience and recommendations!

Hello Felix,
I would like to go into some detail here, as the choice of screws is particularly important with systems like Platsa.
Basically, the Platsa system is made of particleboard, which is not as mechanically strong as solid wood. Therefore, screws with a special thread profile are especially required, one that does not split the material too much but still provides a firm hold. The connecting screws used by Ikea are usually cylindrical cam lock bolts (also called dowels with screw thread or cam fittings), which keep the system modular.
If you want to replace these with your own screws, the following points should be considered:
- Screw diameter: Not larger than the intended drill hole to avoid splitting the wood.
- Thread type: Ideally wood screws with coarse threads that anchor well in particleboard.
- Length: The screw should be long enough to engage at least 12–15 mm (0.5–0.6 inches) into the receiving wood for sufficient grip.
- Material: Stainless steel screws offer corrosion resistance, which is especially useful for kitchens or bathrooms.
I would advise against machine screws, as these usually require a nut and are not ideal for particleboard. This can be mechanically too loose and complicate assembly.
Standard wood screws are helpful if they have a countersunk head so they can be recessed flush without damaging the material. It is also important to pre-drill to prevent splitting.
Also worth considering are so-called “chipboard screws” with partial threading, which provide better clamping force.
Finally, my question to you: Do you want to use the screws just for a secure one-time assembly, or do you plan to disassemble and reassemble the system frequently? This greatly influences the choice.
Best regards!

I recommend 4x40 mm (1.6x1.6 inches) wood screws with coarse threads.That’s correct, 4x40 mm (1.6x1.6 inches) is often a good guideline. However, the length also depends on the material thickness. In the Platsa system, the panel thickness is usually 16 mm (0.6 inches), so 40 mm (1.6 inches) screws hold well without penetrating too far.

What are the advantages and disadvantages of using standard wood screws, machine screws, or possibly special screws?Standard wood screws are versatile, easy to use, and affordable. They are usually adequate for the chipboard in the modules, as long as you choose the appropriate thread type and length.
Machine screws are mainly intended for metal connections; they don’t hold well in wood because they lack self-tapping threads and typically require nuts.
Special screws, such as cam fittings or connector bolts like those from Ikea, are precisely designed for the system, allowing a clean and visually appealing connection with easy disassembly. The downside can be the cost or effort to reorder them.
In my opinion, the best solution is to use the original connector fittings when possible, at least for joining the modules together. For additional elements and mounting to the wall, sturdy wood screws are more suitable.
How extensive is your build project? Do you need screws just for reinforcement or for complete additions?
