Good morning everyone, I am currently planning the installation of an Ikea Metod kitchen and am unsure which screws are best suited for this. My questions are as follows:
- Which types of screws (wood screws, particleboard screws, machine screws, etc.) are most suitable for connecting the Metod carcasses to ensure stability?
- Are there specific lengths or diameters that should definitely be considered, especially since the carcasses are made of particleboard with a melamine-coated surface?
- Should galvanized screws be used to prevent rust, or are standard screws sufficient?
- Are there screws that put less strain on the material and prevent long-term pull-out?
I want to avoid using screws that become loose after a few months or damage the surface. I would appreciate concrete recommendations or tips on which screws are better to avoid.

First, some general thoughts: Ikea Metod carcasses are usually made from particleboard with a melamine coating. This means the material is relatively soft and requires screws that are specifically designed for it. Particleboard screws are generally better because they have a coarse thread that is ideal for this type of engineered wood.
Regarding the dimensions: a diameter of 4 mm (0.16 inches) and a length between 30 and 50 mm (1.2 and 2 inches) are typical. It is important that the screw is long enough to provide a secure hold but not so long that it goes through the back or splits the material.
As for corrosion protection, zinc-plated screws are the minimum since the kitchen can be exposed to some moisture. Stainless steel is an alternative but is often more expensive.
One issue with the Metod kitchen is that overly aggressive screws can cause cracks at the edges. Therefore, it is advisable to pre-drill the holes before screwing or use screws with a pilot thread to prevent the particleboard from splitting.
I would also like to know whether you need the screws only for assembling the carcasses or also for mounting them to the wall and the plinth?

Thank you very much in advance for the answers.
Regarding the last point: My main concern is the connection between the carcasses themselves, where Ikea provides brackets and connector screws, but often you also need to drill and screw them together yourself. The attachment to the wall I will do with special anchors and screws, that is clear.
Pre-drilling sounds logical to protect the melamine surface; honestly, I hadn’t thought of that before.
Are there any screws that might make pre-drilling unnecessary, for example with a special pan head or self-tapping design that works well?

That is a very good question, especially because melamine material is exceptionally fragile. I definitely recommend using chipboard screws with partially threaded shafts, preferably zinc-plated, with a countersunk head so that it sits flush with the surface.
Regarding pre-drilling: The challenge with melamine panels is that the surface is brittle and can chip when screwing. Pre-drilling with a slightly smaller drill bit (about 70-80% of the screw diameter) is very beneficial and significantly reduces the risk of cracking.
Special screws with stepped threads, like the so-called “Spax-type,” have a specially designed thread tip that makes driving easier and can sometimes eliminate the need for pre-drilling. However, I would still always pre-drill, especially on the outer melamine surface, to avoid any risk.
If you want to improve the stability of the joints, using dowels like Festool dowels or similar fastening systems is worthwhile, as they distribute the load evenly.
What has been your experience with the material so far? Do you plan to frequently adjust or reuse the cabinets? Because that influences the choice of screws.
