ᐅ Installing a BILLY Shelf Despite Missing Small Parts – What to Do?

Hello everyone,

I am currently facing a small issue assembling my BILLY shelf from IKEA. Upon delivery, I noticed that some small parts necessary for assembly are missing, specifically a few dowels and screws for securing the back panel. Since I can’t just wait for the replacement parts (which can sometimes take a while), I’m wondering how I can still assemble the shelf so that it is stable and secure.

Do you have experience with missing parts in IKEA shelves? Are there alternatives that can ensure stability without needing the original parts 100%? I would prefer not to compromise on the shelf’s sturdiness, but I’m also unsure how critical the missing screws really are.

Thanks in advance for your tips and advice!

That’s a very good question because the stability of BILLY shelves largely depends on using the correct number and type of fasteners – especially for the back panel. Here are some thoughts on how to approach this:

1. Check if the missing dowels and screws can be replaced with readily available spare parts, for example from a hardware store. With BILLY, the back panel is usually screwed in and fixed with thin metal dowels, which you can replace with common wood screws and matching dowels – provided you pay attention to the same dimensions and material strength.

2. If the back panel is not securely fixed, the stability will suffer significantly because the shelf can twist otherwise. Therefore, you should not only consider the number of screws but also how the back panel is guided and attached.

3. Make sure all connections sit flush and that no screws are too short or too long – one of the most common DIY mistakes is using screws of the wrong length, which can either damage the wood or not provide enough hold.

4. If you mount the shelf to the wall, this can partly compensate for the required stability. But this must also be done with the proper wall fixings.

5. As a last option, you can of course contact IKEA customer service and specifically ask for missing parts – spare parts are often delivered faster than you might expect.

I would be interested to know exactly which parts are missing and whether you have already considered alternatives? The assembly instructions are also helpful to see what functions the individual parts have.

I hope this helps so far. 🙂

Get replacement wall plugs and screws of the same size from the hardware store. Secure the back panel firmly, as this greatly stabilizes the unit. Additional wall mounting is also recommended.

I’d like to add a brief guide on assembling the back panel of the BILLY bookshelf, as this is often underestimated:

1. Check the delivered parts: Take your time to carefully count all screws, dowels, and nails in the package and compare them with the instructions.

2. Alternative fasteners: If some screws are missing, you might be able to use standard nails (such as thin back panel nails, 15–20mm (0.6–0.8 inches) long) as a substitute if they have the same thickness. However, this is only advisable for the back panel—when it comes to load-bearing or movable parts, always use the original screws.

3. Adjusting the back panel: The back panel in the BILLY is often a thin fiberboard that doesn’t carry much load. Its main function is to provide torsional rigidity. Therefore, securing it firmly to the wooden frame is crucial.

4. Wall attachment: Regardless of missing parts, I recommend always securing the bookshelf to the wall. You can do this with the mounting kit from IKEA or your own dowels and screws. This will prevent tipping accidents.

In summary: First check which parts are missing. You can replace very small quantities with suitable standard screws or nails, as long as you match size and strength. If you’re unsure, it’s better to request replacements from IKEA.

If you want, I can also provide more detailed dimensions of the screws and dowels typically used in the BILLY.

Good luck!

I know the feeling when a new piece of furniture doesn’t arrive completely assembled – it’s always frustrating. Especially with BILLY, which is such a classic for many.

It’s important not to get too stressed about it – most of the time, missing small parts can be easily replaced. My recommendation: if you’re unsure about the reliability of the replacement, use an additional wall fixation for safety. This gives you peace of mind and reduces the pressure that every single part has to fit perfectly.

I can only reinforce that. Sometimes a few simple tricks make the assembly less stressful, and you can still enjoy the furniture.

Don’t worry, you can do it!
