ᐅ What should I do if screws break while assembling the IKEA Besta unit?

Thanks in advance for the information!

A question from my side: If I manage to remove the screw completely, what exactly should I do afterward to ensure that the hole isn’t damaged and the cabinet remains stable?

Should I use a larger replacement part, or does IKEA offer specific repair kits? I've also read about using wood filler or glue for reinforcement. What are your thoughts on this?

And how much pressure is safe to apply on the Besta? Of course, I don’t want to cause any new damage.

Good question!

If the hole became slightly frayed or enlarged when removing the screw, I recommend the following steps:

- Carefully fill the hole with a suitable wooden dowel. These come in various diameters; it’s best to use one the same size as the original screw.
- Apply wood glue to the dowel before inserting it to ensure a strong bond.
- Allow the dowel and glue to dry thoroughly (at least 24 hours).
- Then screw a matching screw into the dowel.

Under no circumstances should you simply use a larger screw without preparation, as this often weakens the structure. Some IKEA repair kits include matching dowels and glue; otherwise, visit a hardware store.

Regarding the pressure when screwing in: patience is key. IKEA often uses particleboard, which can easily split. Apply light to moderate pressure and turn in small increments—the material needs time to avoid cracking.

Using both dowels and glue is the best method when the hole has become worn out. Otherwise, stability is quickly lost.

If a screw breaks: remove the screw, fill the hole with a wooden dowel and glue, let it dry, then insert a new screw.

I completely agree. It is always a mistake to just force in thicker screws. This often causes more damage. It’s better to properly repair the hole and prepare it accordingly.

I always think it’s best not to force the screwdriver too much during assembly – rather turn it carefully and take breaks more often. The components are sturdy, but wood and particle board are not indestructible.

And don’t worry if something breaks! These small mishaps can be fixed, sometimes you just need a bit of patience 🙂
