Hello everyone,
I am currently dealing with an issue that many users of Billy shelves probably know: Why do the screws in Billy shelves lose their grip over time?
I’ve noticed that after some use, the screws that hold the shelves or side panels in place become looser, even though I haven’t changed anything obvious regarding the load.
I’m interested in whether this is due to material fatigue, incorrect assembly, or generally the design and construction of the shelf. I would also like to know if there are any proven tricks to tighten the screws properly again without having to drill completely new holes or damage the shelf.
What causes are you aware of that lead to the screws in Billy shelves losing their hold? Are there any specific tips or experiences for fixing this? Thanks in advance for your insights!

Hello danpeo,
Regarding your topic: Screws in IKEA Billy shelves often lose their grip because the particleboard material used to make the shelf gradually loses its original stability over time and with use.
That’s a good point – the cause is usually a combination of three factors: First, the quality of the particleboard used in the shelf. It is sensitive to tensile and compressive forces and can expand and contract with changes in temperature and humidity. This causes the screws to loosen over time.
Second, the screw threads are designed for the material, but frequent tightening or small movements progressively enlarge the hole in the particleboard.
Third, assembly errors such as overtightening the screws or repeatedly repositioning parts can also affect the stability.
A tip for repair: Sometimes using a dowel or special wood filler helps to restore the enlarged hole. Alternatively, applying some wood glue or inserting small wood pieces before re-screwing can improve the fit.
Feel free to ask if you need more specific information about repair methods!

Hello danpeo, hello Filippo,
I would like to revisit this topic and add a few points:
Billy shelves are known for their screws loosening over time – this is actually a combination of material quality and load.
This is a key point. Especially when furniture is placed in more humid rooms or near radiators, the wood moisture content fluctuates, which leads to the screw holes becoming loose.
Another factor is the tensile strength of the screws used and their thread design. "Standard" screws might not provide a sufficiently tight fit. IKEA uses special screws with so-called chipboard dowels that fit into the holes, but even these can loosen if, for example, the shelf parts are repeatedly assembled and disassembled.
My tip for immediate improvement: after removing the loose screw, fill the hole with toothpicks or small wooden pieces, glue them in, and then screw the screw back in. This creates new grip.
For the long term, if frequent tightening is needed, I recommend reinforcing with wood glue and dowels, especially at the load-bearing points, if the shelf is heavily loaded. This protects the furniture and prevents faster material fatigue.
Hope this helps those asking!

I really appreciate how Filippo and Benon explain this – it also reflects my own experience.
What bothers me about this topic is partly the feeling that these shelves aren’t really built to last. I ignored the problem for a while until I noticed how wobbly the whole shelf had become. It feels unsafe, especially when placing heavy books on it.
I can only confirm that. I did it that way, and as a result, the shelf is very stable again. Still, sometimes I wonder if I should use the shelf less or if the screws just need to be tightened too often, which gets frustrating over time.
I’m curious if IKEA might be planning improvements or if there are alternative replacement screws that hold better? I’d like to hear such experiences here.
Even though I’m not very skilled with tools, I still try to optimize the shelves so they last longer – especially with such an affordable piece of furniture, otherwise everything feels a bit worn out.

For this discussion, I would like to objectively point out that the main issue with Billy-style shelves lies primarily in the material used: particleboard and its lower mechanical strength and dimensional stability compared to solid wood.
This factor causes the typical loosening of screw holes. Screws generally hold well in particleboard, but the stress area around the screw becomes more fragile with increasing load. Incorrect tightening—for example, over-tightening—can damage the wood fiber network and significantly reduce the lifespan of the joint.
To repair this, precise methods are recommended: filling worn screw holes with a mixture of wood dust and wood glue, careful drying, and using properly sized screws with coarse threads designed for particleboard. Alternatively, dowels can be used to reinforce the connection.
It is important to keep all loads on the shelf within reasonable limits. This applies particularly to the load capacity of the shelves, which in Billy-style shelves is not designed for very heavy weights.
Optimized assembly—such as following recommended torque settings and avoiding frequent screwing and unscrewing—can significantly extend the durability of the screw connections. For a truly long-lasting piece of furniture, it is advisable to use other materials like solid wood or higher-density MDF.
