Hello everyone, I recently modified my Billy bookshelf and noticed that some of the original screws need to be replaced due to rust and material fatigue. Now I’m wondering which screws can be used as replacements for the Billy to ensure the shelf’s stability and safety. It’s important to me that the replacement screws match in size, length, and thread type, and are also compatible with the material of the shelf—I obviously don’t want to use screws that could damage the wood or don’t provide the necessary load-bearing capacity. Does anyone have experience with suitable replacement screws for Billy bookshelves or can offer specific recommendations? It would also be helpful to know if there are alternatives that are even more durable than the original screws. Thanks in advance!
Interesting discussion here.
I would like to add one point: Some recommend fine-thread screws, while others mention particleboard screws. It is important to understand that particleboard screws usually have a special thread design that differs from standard metric fine-thread screws. These are often self-tapping and optimized for wood-based materials.
That seems correct to me but quite general. I would focus more on quality and manufacturing—specifically whether the screws are certified for particleboard or MDF. Cheap replacement screws from hardware stores often don’t fit well.
That is a very important point. Additionally, I recommend performing small tests on the inner edge of the shelf before final assembly, especially if the shelf is older or has been exposed to moisture.

metric screws in M4 or M5 with full thread, since partial thread often does not guarantee holding strength.

Always test replacement screws first to ensure they screw in smoothly without damaging the wood.
