ᐅ Why are the connectors on my BILLY shelf coming loose?

Hello everyone, I have an issue with my Billy bookshelf where the connectors keep loosening, even though I assembled them correctly. The bookshelf is placed on a level surface and is not subjected to excessive load. The screws are initially tight, but after a few days or weeks, they loosen on their own, causing the bookshelf to become unstable and sometimes slightly wobbly.

Can anyone explain why this happens? Could it be due to the material, the assembly, or the type of fasteners used? I even treated all the screws with an appropriate thread-locking compound, but the problem still occurs. Is there a way to fix this permanently without having to take the bookshelf apart? Any advice or shared experiences would be greatly appreciated, thanks!

My recommendation is to periodically tighten the connectors after assembly.

I generally do the same, but in my case, I hardly touch the shelf after a few days and the joints still come loose. This suggests there might be material or assembly issues.

A workaround could be screws with a slightly longer thread length and dowels in the drilled hole

Here is my question: Does anyone have experience with alternative fasteners for BILLY shelves that hold better? Perhaps adapters or retrofit solutions? I don’t want to significantly damage the original parts in case I want to return the shelf later.

If you are looking for alternative solutions, I recommend wood glue combined with strategically placed wooden dowels instead of the original chipboard screws.

You can first slightly loosen the screws, insert dowels into the holes, then lightly lubricate them and secure everything with glue. This significantly increases the tensile strength.

Caution: This is more of a semi-permanent solution, as the shelf will be difficult to disassemble. For better durability, wooden dowels are the right choice, even though it requires a bit more effort.

Alternative fasteners for BILLY shelves

There are no official retrofit kits from IKEA, but in the DIY sector, special furniture brackets are often used that can be mounted externally to improve stability.

Although this affects the appearance, it provides a lasting solution for loose connectors. Another option is metal corner brackets, which can be screwed inside or outside the shelf board.

One more tip: When assembling, use a hex key with a torque wrench function or apply a consistent feeling when tightening. Too much force can damage the material, while too little can result in loose connections.
