ᐅ Repairing KALLAX Screw Damage – Using Wooden Dowels?

Hello everyone,

I have a problem with a stripped screw hole on one of the shelf supports in my IKEA KALLAX shelf. The screw has basically come loose from the wood of the panel material and can no longer be secured. Now I’m considering whether I can fix this issue using wooden dowels.

My idea is to enlarge or cut out the old screw hole, insert a suitably sized wooden dowel (e.g., 8 mm) with wood glue, and then drill a new pilot hole for the screw.

Has anyone had experience with this? Is this a reliable repair method that can withstand the load typical for a KALLAX shelf (which often has to carry quite a bit of weight)? Are there better or more proven alternatives for repairing stripped screw holes in furniture panels like MDF or particleboard, which IKEA uses?

I would appreciate it if you could share your opinions, experiences, or tips. Thanks!

Hello, erikgau,

Unfortunately, I know this problem from my own KALLAX and understand how frustrating it is. I once tried a repair using wooden dowels. It basically works if the dowel fits properly and enough wood glue is applied. It’s important to choose the exact right diameter and to press the dowels firmly into the board – a precise fit really makes the difference.

However, I never feel completely confident with this method for permanent loads, especially with KALLAX shelves, which can be quite heavily loaded. I’ve sometimes worried that it might fail again if too much weight or movement is applied.

Personally, I would also add small metal brackets or connectors as extra reinforcement where possible, both for better strength and practicality, if it doesn’t affect the appearance too much.

Have you already tried reinforcing the board at the damaged spot?

I hope this helps for now. It’s really a tricky issue that I wouldn’t approach with full confidence either, but often only practical solutions are possible. 🙂

Yes, exactly. Precise drilling and fit are essential when inserting wooden dowels.

Alternatively, threaded inserts for wood or larger furniture connectors can be used. These are more durable and provide additional stability.

Wooden dowels are acceptable but not the most robust solution.

Your idea of using wooden dowels is basically understandable, but let’s take a closer look at the material properties: KALLAX elements are usually made of coated particleboard or MDF, whose fiber structure and bonding give way when damaged. Wooden dowels work best in solid wood, not in coated panel materials.

That is exactly the point. The risk of tearing out again remains high if you rely solely on dowels. A combination of dowels with clamps or angle brackets might be better.

I agree with that. Also, insert nuts or special dowels with metal threads significantly improve load capacity. For a more professional approach, these solutions are preferable.

In conclusion: Wooden dowels are acceptable for a temporary repair, but for permanent load on the shelf—especially when it comes to weight on the shelf board—I would recommend using stronger fastening systems.
