Hello everyone,
I am currently working on a kitchen project using the Ikea METOD system and have questions about which screws are specifically required for the special connections in this system. I have already looked through the standard packages but find some connection points unclear or only general instructions provided in the manual.
Specifically, I am interested in:
- Which types and lengths of screws are best suited for connecting the carcasses to each other?
- Which screws are recommended for mounting the METOD cabinets to the wall to ensure maximum stability?
- Are there screws that should be used specifically for installing the drawer runners in the METOD system?
I want to make sure I use the correct screws since I want to avoid warped or unstable constructions. Maybe someone here has relevant experience or precise recommendations on which screws (type, length, diameter, material) are ideal for these specific METOD connections.
Thanks in advance for your support!

Hello Andrinla,
your question is very well put and important because, especially with system furniture like METOD, the choice of screws is crucial for stability and durability. Here is a brief overview based on years of assembly experience and the original Ikea guidelines:
- For the cabinet carcass connections between units (for example, when joining multiple cabinets), Phillips screws with a diameter of 4.0 mm and a length of 30 mm (approximately 1/8 inch by 1 1/4 inches) are usually the best choice. Ikea often uses coarse-threaded particleboard screws to ensure a particularly strong hold in chipboard.
- For the wall mounting of the METOD cabinets, you should definitely use screws with appropriate wall plugs (depending on the type of wall). The screws should be at least 6 mm thick and at least 60 mm long (about 1/4 inch by 2 1/4 inches) to provide secure anchoring in the wall. If possible, use countersunk head screws, as flush fitting into the mounting hole is typical.
- The drawer runners are usually fastened with smaller screws, mostly 3.5 mm diameter and 20 mm length (roughly 1/16 inch by 3/4 inch). These are supplied directly by Ikea but should definitely be zinc-coated to prevent corrosion.
One tip: avoid using screws that are too long for carcass connections, as you might drill through the material. Use a depth stop on your cordless drill.
If you like, I can also prepare a list of suitable screw types with dimensions for you.

These were exactly the points I was unclear about at the moment. What I’m still not entirely sure about: do you recommend using cam lock connectors with matching screws for joining the cabinet corners, or would you suggest solely screw connections? Sometimes I read that cam locks significantly improve stability, but that the type of screws used may vary accordingly.
And regarding materials: should I definitely opt for galvanized screws, or is stainless steel sufficient? I plan for the kitchen to potentially experience occasionally more humid conditions.

What I’m not quite sure about yet: Do you recommend using cam connectors with matching screws for joining cabinet corners, or just simple screws?Cam connectors are definitely the preferred choice if you want a strong yet reversible connection. They are even standard in the METOD system, especially for the cabinet corners. These connectors require special screws, usually 5 mm diameter and 30 mm length (about 1/4 inch by 1 1/8 inch) – they often come as part of the cam connector kit and are a bit sturdier than regular chipboard screws used for individual panels.

And regarding materials: Should I strictly use galvanized screws, or is stainless steel sufficient?Galvanized screws offer good corrosion protection and are usually sufficient considering the cost-benefit ratio. Stainless steel is better for wet rooms in the long term because it is rust-resistant. So if you expect frequent moisture in the kitchen, stainless steel screws are recommended, especially for drawer assemblies and hardware fittings.
In summary:
- Cam connectors plus matching screws for cabinet corners
- Galvanized for standard use, stainless steel for moisture exposure
I’m happy to explain the functions and applications of the different connectors in more detail if needed.
In addition to my previous post, I would like to emphasize the importance of screw quality, especially when using modified or alternative screws outside of the Ikea supply.
- For cabinet edges and surfaces, coarse-thread screws are essential as they provide better grip in wood-based materials such as particleboard.
- The screw length should be chosen so that at least 10 mm (0.4 inches) of thread engages in the wood without the screw protruding on the opposite side.
- When fixing to the wall, selecting the appropriate wall anchors is even more important than the screws themselves. Screws alone are not a substitute for suitable wall plugs.
Another point: If you install additional reinforcements (such as metal brackets in corners), be sure to use screws with larger heads and higher strength (approximately 5.5 mm (0.2 inches) diameter) to effectively transfer shear forces.

I would like to add a few practical tips:
- It is often underestimated how important pre-drilling is when using chipboard screws. Drilling too narrowly or not drilling at all can split the wood or weaken the screw connection.
- For METOD connections, you can use the original screws from Ikea or equivalent chipboard screws. The important factors are the combination of diameter, length, and thread type.
- If you don’t want to order original screws, use Phillips-head screws, zinc-plated, with a diameter of 4 mm (0.16 inches) and a length of 30 mm (1.18 inches) for carcasses, and 3.5 mm (0.14 inches) diameter and 20 mm (0.79 inches) length for fittings.
- When mounting on walls, be sure to consider the wall material (concrete, drywall/plasterboard, brick) and use appropriate anchors with 6 mm (0.24 inches) thick screws of sufficient length.
I recommend paying special attention during assembly to the alignment of the screw holes and tightening the screws firmly, so the joints do not loosen while the adhesive sets.
