ᐅ Retrofitting Billy Regal Screws – Which Replacement Parts Are Durable?

Hello everyone, I want to replace the screws on my IKEA Billy bookshelf because some have become worn out or broken over the years. My specific question is: based on experience, which replacement screws or fittings are more durable than the original screws from the Billy bookshelf and also fit the existing holes and connection system? I am looking for a long-lasting solution that makes the shelf more secure, especially when it is filled higher and carries somewhat heavier loads. I have considered metal screws, stronger wood screws, and alternative fasteners like metal brackets, but I am unsure which replacement parts are the most effective and easiest to install. Thanks in advance for your advice!

I recommend using galvanized metal screws with a diameter of at least 5 mm (0.2 inches). They usually fit well and are significantly stronger than the thin original screws. If you locate the drill holes, just replace the screws.

Hello Cemgu, your concern is understandable, as the original screws used in Billy shelves are often not ideal for heavy loads or longer use. In general, you can replace the supplied wood screws with high-quality furniture connectors using metal screws. Make sure the screws are not too long to avoid splitting the material.

As a replacement, I especially recommend screws made of galvanized steel or stainless steel, as they are rust-resistant and more durable. Also, special chipboard screws with coarse threads improve the grip in the frame connections.

If possible, you can additionally use metal brackets to enhance corner stability, especially when the shelf is loaded with heavy books.

If you need examples, I can gladly provide some item numbers.

Thank you for the helpful tip, that sounds reasonable. Could you also share some advice on the appropriate screw sizes for Billy shelves? What length and diameter are ideal? And do you have experience with whether it’s okay to reuse the existing holes, or if it’s better to make slight adjustments? The drill holes are usually not very large.

Hi Cemgu, I replaced the original screws in several Billy shelves with high-quality stainless steel chipboard screws. I always used screws about 4mm (0.16 inches) in diameter and 35mm (1.4 inches) long, which fit very well into the holes.

If the holes are a bit worn out, I use countersunk screws instead of the original ones, which can also be securely reinforced with a bit of wood glue or dowels. This makes the shelf significantly more stable and durable.

I know exactly how frustrating it is when the screws suddenly give way and the shelf becomes wobbly – especially when you have important items on it.

Using stainless steel screws combined with wood glue or wall plugs makes it much more stable.

That sounds really promising, I will give it a try as well. I’m also curious if anyone has experience with self-adhesive metal brackets? I’ve heard they can significantly increase stability without heavy drilling, but I’m not sure if they hold up over time.
