ᐅ Why do screws come loose on Billy shelves despite being securely installed?

Hello everyone,
Lately, while assembling my Billy shelves, I have repeatedly noticed that screws seem to loosen by themselves, even though I tightened them properly. This surprises me because the assembly was solid and done with the right tools. Does anyone know why screws on Billy shelves can keep loosening even when installed correctly? I suspect it might be related to the material properties or the screw system, but I would appreciate a well-founded explanation or any experiences. Thanks in advance!

Screws loosen because the material expands and contracts. This happens faster with engineered wood than with solid wood. The connection is not rigid but flexible.
If the screws are tightened too much, the material will tear out. It is better to retighten them several times.

Replacing original parts with standard screws does not always work smoothly.Exactly, with IKEA shelves, a precise fit is very important. Using incorrect screws can cause uneven stress and contribute to loosening.

Occasional retightening after a few months is therefore recommended.That sounds reasonable, thanks! I actually thought that regular retightening was a sign of poor installation or low quality.

The material contracts and expands, so it’s better to be cautious when tightening.True, I probably overtightened at times to make sure the screw was “seated properly.” I’ll try retightening and be more gentle next time 🙂
To provide a concise guide:
1. When assembling, first tighten all screws by hand only.
2. Then gradually tighten them using a torque wrench or a suitable screwdriver.
3. After about 4–6 weeks, check all screws and gently retighten if necessary.
4. Distribute loads evenly whenever possible.
5. For heavy loads, install spring washers or alternatively try threadlocker (Loctite).
This procedure significantly reduces the risk of screws loosening.
