ᐅ Why do the connectors in BILLY shelves come loose, and how can I prevent this?

Hello everyone,

Lately, I’ve been having recurring issues with my Billy shelves where the connectors – that is, the screws, dowels, and especially the metal cam lock screws – loosen or even come apart completely after some time. This seems to happen even without the shelf being heavily loaded or moved. I’m curious about the most common reasons why these connectors come loose in Billy shelves and how this can be effectively prevented.

Are there any specific assembly tips to keep in mind, or are there weak points in the design that one should watch out for?

I look forward to your experiences and advice!

In my experience, in addition to tightening the screws firmly, applying some wax or assembly paste to the connector bolts also helps. This reduces movement and loosening over time.

Interesting thread.

However, I wonder if the issue might also be structural: BILLY shelves are relatively inexpensive and made from basic materials. The design and joining methods may be intended more for temporary furniture.

Could it be that under heavier use or frequent transport, the connecting parts are simply undersized and therefore come loose easily?

The BILLY shelf uses a construction made of particleboard, which has relatively low density and load capacity.

That seems to me to be the core of the problem. Perhaps from the start, reinforcements should be considered—either with metal brackets behind the shelves or wider screws.

I also wonder if anyone has experience with alternative joining systems that perform better than the standard BILLY fittings.

A brief note for prevention:

1. Installation check: Retighten the screws after a few weeks.
2. Distribute the load evenly.

This is usually enough to prevent the connectors from loosening on BILLY shelves.
