Hello everyone,
A few months ago, I modified and expanded a KALLAX shelving unit from the IKEA range according to my ideas – unfortunately, one of the components has since become loose, meaning the joints are no longer stable, and the shelving wobbles significantly more than before. This concerns the modular extension with several shelves and the additional interior frame that I attached with wood screws.
I am particularly interested in finding out what options exist to reinforce KALLAX modules afterwards or to fix loosening issues, especially when modifications with additional fasteners have been made. Are there proven repair techniques or specific materials that are recommended?
I want to avoid buying a completely new shelving unit and am looking for practical solutions that also handle the structural load. I am very much looking forward to your tips and experiences!

Hello hubertgo,
I fully agree with the suggestions from Domau0 and KAULIS and would like to add a few details:
1. Layer the process: Fill holes with precisely fitting wooden dowels plus wood glue. Important: Use not just simple dowels, but ones with grooves or spiral patterns that hold firmly.
2. Screw quality: Choose at least hardwood screws with a length that penetrates the material by at least 25mm (1 inch) to ensure better holding strength.
3. Also use the original IKEA metal brackets or similar galvanized brackets – make sure the brackets have no sharp edges and sit evenly.
4. For particularly loosened spots, installing threaded inserts (brass or steel) can significantly improve the connections. Although a bit more work, they provide a long-term solution when the original holes are worn out.
If you want, I can also write you a step-by-step video guide showing how I stabilized my KALLAX through self-made modifications?

Is the shelf subjected to heavy loads over time (e.g., books, equipment) or is it more moderate? Also: What exact modifications have you made? Did you possibly use different materials than the original KALLAX?Thank you for the detailed questions; that definitely helps with the assessment. The shelf is used as a bookshelf in my study, so the load is moderate to heavy (partly heavier books).
The modification mainly involved adding extra cross braces made of solid wood to provide more stability for the shelves – however, the braces were attached with small screws directly into the side panels. The core issue is that the screw holes have become enlarged over time, which causes wobbling.
Most of the original KALLAX parts are still intact, only supplemented with the cross braces made of spruce/fir.
I am particularly interested in practical repair options for the screw joints, preferably without fully disassembling the unit.

I am especially interested in practical repair options for the screw connections, preferably without completely dismantling the module.Since your focus is on repairs without disassembly, I recommend using wood filler or a two-component epoxy wood filler to fill worn-out holes. These can be applied without removing the module and cure to a hard finish. After curing, you can screw new screws directly into the repaired area.
Make sure to allow sufficient drying time (at least 24 hours). When screwing in, avoid applying excessive torque.
Does that sound feasible for you?

However, I am concerned whether the strength of the repaired areas remains sufficient after this treatment. Does anyone have experience with the load-bearing capacity of epoxy wood filler in such repairs? Is it really strong enough for bookshelf shelves?
Epoxy wood fillers are an excellent choice for worn-out holes, as they become extremely durable and strong once cured. It is important to press the filler firmly into the holes to avoid any air pockets.
For bookshelves, I consider this a long-term solution, especially when combined with appropriate screws.
Avoid overtightening the screws during installation, as this can cause the material to crumble.

1. One way to improve the holding power of screws is to pre-drill with a slightly smaller drill bit than the screw itself, allowing for controlled work and preventing weakening of the wood.
2. If a visible reinforcement is acceptable, wooden blocks can be glued into the inner corners to provide additional resistance against twisting.
This keeps the repair manageable and significantly improves stability.
