I recently assembled a KALLAX shelving unit from IKEA and noticed that the screws sometimes completely strip when being tightened or loosened, especially in some of the thinner parts. This causes the shelving to become wobbly or even results in individual joints coming loose. My specific question is: Are there any proven repair tips to sustainably fix this screw issue? For example, do certain repair kits, special inserts, or alternative fastening methods help? I would also appreciate advice on whether the material itself can be reinforced somehow without having to disassemble the entire shelving unit.
Thanks in advance for your expertise!

Hello Stefanvin,
I am familiar with your issue of screws stripping in KALLAX furniture, as the particleboard is often somewhat soft and does not tolerate much force when screws are repeatedly loosened and tightened.
First, you should check whether the screw holes are already damaged or swollen. If so, I would recommend repairing the holes with wood filler or, even better, a two-component wood repair kit. These kits cure very hard and provide a new, solid base.
An alternative is to fill the holes with a beechwood dowel (also called a wooden plug) and wood glue. The hole is then drilled slightly larger, the dowel glued in, and after drying, the screw hole is re-drilled with a smaller drill bit. This gives even more stability than the original material.
If you don’t want to take the shelf apart, there are also so-called screw fillers that are inserted into the hole, harden, and then allow the screw thread to be re-cut. This is practical if the furniture is already assembled.
It is also advisable to use screws with a slightly stronger thread or wood screws with special countersunk heads. Sometimes a little Teflon tape wrapped around the screw can also help stabilize the connection.
Feel free to share details about your exact types of screws and the problematic holes, so I can provide more targeted advice.

For the screws themselves, I recommend countersunk screws with depth control to prevent over-tightening. For stripped holes, it is also possible to use plastic inserts (brass or aluminum threaded inserts), which can significantly increase durability. However, this usually requires removing the affected parts.
If that is not possible, as a temporary solution, applying a drop of medium-strength threadlocker (such as “Loctite”) often helps reduce screw loosening.
I find this topic really important because many people buy the KALLAX shelf specifically for its quick assembly and then fail due to these exact screw problems.
I personally had the same issue and initially felt uncertain because assembly instructions often don’t mention these types of damages. I can fully understand how frustrating that can be.
One key piece of advice I received is not to tighten the screws too much, but to use a sense of torque. Otherwise, the material starts to break down quickly.
Even though it sounds obvious, I would recommend testing the screws after inserting them with a slight angle—not just using force, but also observing exactly where they catch or turn. That’s how I was able to spot major damage early on 🙂

That causes the shelf to become wobbly or even some connections to come loose completely.Hello Stefanvin,
I am familiar with this problem and would like to add: when screws strip, it’s usually not just the material itself but a combination of the material, type of screw, and handling. Therefore:
1. Preferably use wood screws with a coarser thread and an appropriate diameter.
2. When repairing, it’s recommended to always use wood glue, as it creates the strongest bond later on.
3. Be careful to tighten the screws gently and avoid using cordless electric screwdrivers with high torque.
4. For difficult cases, you can even use thread inserts (Helicoil or M4 inserts) if you can partially disassemble the shelf. This requires some work and patience.
If you have any further questions, I’m happy to help.
