ᐅ Which screws are best for preventing wobbling in IKEA Brimnes furniture?

Hello everyone, I have a somewhat specific question: which screws are best at preventing IKEA Brimnes furniture from wobbling? I’ve noticed that my Brimnes bed frame, despite being properly assembled, still wobbles slightly, especially when moving. The original screws don’t seem to hold very tightly, and I’m considering whether different types of screws might work better. Are there particular screws that, due to their length, diameter, or material, provide a more stable connection? I would appreciate any tips or experiences, especially if anyone has compared the original screws with alternatives.

Hey ioannismin, I think your question is great because a wobbly bed can really be annoying! 😅 I had the same problem with my Brimnes bed and found that using slightly longer screws with a stronger coating instead of the short, thin original screws helped a lot. Ideally, you should choose screws that are a bit thicker than the originals and made of steel (perhaps galvanized or rust-resistant), as they grip the wood better. If the screws are too long, you can simply shorten them a bit or measure beforehand to make sure they don’t go in too deep. My tip: look for chipboard screws with a thread designed to hold wood securely. After that, the bed was almost like new and no longer wobbly! 😎

I would like to briefly point out that simply replacing the screws does not automatically resolve the cause of wobbling. It largely depends on how the screws function within the piece of furniture—that is, whether the screw fit is tight and how the furniture panels are constructed. You should also check whether the material itself has been damaged from repeated assembly and disassembly or if the joints are misaligned. Simply using thicker screws can even be counterproductive if it causes the wood to swell or crack. So, before buying new screws, it’s important to identify the cause, and if the original screws are too short or too thin, replacing them with higher-quality chipboard screws might be sensible. However, this is not a cure-all solution.

Hello ioannismin, I want to go into some detail because I have restored several Brimnes parts myself. The wobbling often comes from the combination of the economical material thickness (particleboard) and relatively short screws. The standard screws are often 4 mm in diameter and 30 mm in length, which is quite limited for the thin material. To improve this, I recommend:
- Screws with a diameter of 4.5 to 5 mm
- Length around 40 to 50 mm, but only if the furniture panel has the necessary thickness (otherwise, do not use screws that are too long)
- A coarse-thread screw, that is, particleboard screws, which provide good hold in the wood

A good method is to carefully clean the original holes first and then fasten again with a new set of slightly thicker screws. The choice of screws also depends on whether you use metal screws or wood-thread screws. Metal screws grip less well in particleboard.

Could you maybe specify where exactly the wobbling happens most on your furniture? Is it the side panels, connection points, or the bed frame as a whole?

Thank you for the detailed response! The wobbling is mainly noticeable at the joints between the headboard, footboard, and the side panels. Sometimes it feels like the screws aren’t tight enough, even though I have already tightened them properly. I suspect the holes might be slightly worn out in my case. Would drilling them out again and using wood filler or something similar help before I use new screws?

Hello ioannismin, a simple wood filler often does not provide a long-lasting solution for stripped screw holes. It is better to repair the holes using wooden wedges or properly sized wooden dowels.

Here is the best approach:
- Remove the screw and clean the hole of any loose fibers
- Apply a small amount of wood filler to fill the initial indentation
- Then press a wooden dowel that fits the hole precisely, coated with wood glue, into the hole
- Let it dry thoroughly
- Drill the hole again for the screw and insert the appropriate screw

This creates a solid hold and prevents further looseness. It is important that the dowel fits tightly in the hole and that the wood glue provides stability.
