ᐅ Replacing all screws in a BILLY shelf – is it necessary?

Hello everyone,

I have a specific question about the IKEA Billy bookshelf, which is common in many homes. I have noticed that the original screws and fasteners can sometimes become a bit loose or unreliable over time—often due to frequent moving or stress. Now I’m wondering if it would make sense to replace all the screws in the Billy bookshelf with higher-quality ones, for example stainless steel, to improve long-term stability.

Has anyone had experience with completely replacing the screws? Is it really necessary or a bit excessive? Are there specific types or sizes of screws I should pay attention to in order to avoid damaging the shelf? And could this somehow improve or worsen the assembly or durability?

Thanks in advance for your opinions and advice!

Good morning,

I would like to organize my response to show you a practical approach for identifying the screws on the BILLY shelf and, if you want, how to replace them safely.

1. Determine the type of screw:
- Remove a screw from the shelf (for example, one you can access through a hole in a drill hole).
- Measure the length (total length without the head) using a ruler or caliper.
- Measure the diameter of the thread (e.g., 4 mm (0.16 inches), 5 mm (0.2 inches)).
- To determine the thread pitch, you can use a thread gauge that shows the number of threads per centimeter.

2. Identify the screw type:
- The original BILLY screws are usually chipboard screws with a flat head or countersunk head, mostly zinc-plated.
- Some connections use so-called cam fittings, which do not require screws for replacement.

3. Replacement:
- Only replace with screws of identical dimensions and preferably stainless steel for rust protection.
- Avoid screws with too coarse a thread to prevent damaging the pre-drilled holes.

Summary:
If you carefully measure the existing screws and obtain identical replacements, there is nothing preventing you from replacing them. There are no hidden special features in BILLY that make this impossible.

Hope this helps!

I completely understand why you’re being so careful. Sometimes furniture can feel unstable or worn out, which raises concerns. I had a similar experience with my BILLY shelf and wasn’t sure if I might damage it by loosening everything.

That sounds great! I appreciate when positive experiences are shared—it’s encouraging.

I also think it’s important to mention the screw size—you want to avoid screws that are too thick, or you might end up with cracked drill holes later. I’d recommend proceeding very carefully, step by step, and maybe start by replacing only the most important screws first.

Please keep us updated on how your project progresses!

Thanks to everyone for the detailed answers and tips!

Yesterday, I removed a few screws and started measuring – the length and diameter actually match standard chipboard screws quite well, and the thread pitch seems to be rather fine.

I will probably stick to stainless steel variants with identical dimensions, as recommended by Jensson.

I’m curious to see if this will provide better long-term stability. If anyone has more experience or tips regarding installation, please share!

Wishing everyone a great start to the day 🙂
