Hello everyone,

I am currently facing an issue with my IKEA KALLAX shelf: one of the connectors that hold the individual shelf parts together has broken. Specifically, it’s one of those round plastic pieces that you insert into the drilled holes and then screw in to securely join the side panels. Since the connector is located at a load-bearing point, I’m wondering what the best way is to replace a broken connector like this.

Are there suitable spare parts available from IKEA or alternative options that work well? I don’t want to replace an entire side panel or the whole shelf, but rather repair it as cost-effectively and securely as possible. It would also be helpful to know whether these replacement connectors are easy to purchase separately, or if DIY solutions or other types of fasteners might be recommended.

Looking forward to any advice, tips, and your experiences!

Thanks in advance!

IKEA sells the connectors as spare parts, usually under "KALLAX connectors." Alternatively, you can use M6 furniture screws with metal anchors from a hardware store. This provides sufficient stability.

Hello Nelelis,

I’m familiar with your problem, as the KALLAX system uses these special screw connectors that aren’t always very durable. If the connector is broken, the first step is to carefully measure the hole and the size of the connector. IKEA offers replacement connectors for almost all of their furniture—you can ask for them at the IKEA store service desk or search online under "IKEA hardware." Even if you don’t know the exact name, their website often has search filters.

If you can’t get original parts, I recommend metal connectors (furniture connectors with metal threads). These aren’t original but tend to last longer and provide better stability. It’s important that the connector fits precisely into the pre-drilled holes; otherwise, the repair may feel unstable later on.

Good luck with the repair, and feel free to ask if you have any more questions!

Hello everyone,

I would like to share a brief guide on repairing broken KALLAX connectors, based on my experience:

1. Damage analysis: Carefully check which part of the connector is broken – often it is the head that secures the screw, or the tapered insert that grips into the wood.

2. Original replacement: IKEA usually only sells complete connector sets or replacement kits suitable for the shelf model. In many cases, these are difficult to obtain individually. Therefore, the alternative:

3. Alternative fasteners: Furniture connectors with metric threads (M6) from hardware stores can be used instead of the plastic connectors. It is important to slightly adjust the hole in the side panel so the metal connector fits properly.

4. DIY solution: If no suitable connector is available, a stable base can be created using plastic repair epoxy and a fragment of an old dowel to insert the metal connector.

5. Long-term stability: It is recommended to reinforce the connection with wood glue on the contact surfaces after repair and avoid overtightening when screwing.

In summary:
IKEA replacement parts are the first choice but not always available. Metal connectors from hardware stores are an excellent alternative, provided you adjust the holes accordingly. For those skilled in DIY, epoxy combined with a metal thread can provide an even stronger connection.

If you like, I can send you a step-by-step guide.

I agree! Plastic bends easily, metal holds much better. I once repaired my KALLAX with stainless steel furniture screws. It didn’t look 100% original at first glance, but it holds really firmly. 🙂

You just have to pay attention to the correct length, otherwise you might damage the shelf board. Oh, and a bit of PTFE tape or felt pads for protection also helps if you screw and unscrew the connector often.

If you want, I can gladly share my sources for suitable replacement nuts.

Buy M6 screws with matching metal wall plugs at the hardware store; that works well. The plastic connectors often become brittle, metal ones hold up better. Simply remove the old part, insert the new one, and you're done.
