ᐅ KALLAX hinges repeatedly become loose after tilting – is this a screw issue?

Hello everyone,

I have a specific problem with the hinges on my KALLAX shelving unit. Whenever I tilt the doors slightly open and then close them again, the hinges become loose over time. This causes the doors to no longer fit properly, wobble, or shift. I’m especially interested in whether this is a common issue with the screws—meaning if they tend to loosen systematically with use—or if it might be related to the installation or the material of the hinges.

I have tightened the screws several times already, but after a while they loosen again. Can anyone share similar experiences or offer tips on how to prevent this from happening permanently? I would appreciate advice on whether there are special screws, thread-locking adhesives, or practical tricks that could help stabilize the situation.

Thanks in advance for your time!

Thread locking is mandatory.

Even better: use screws with a larger diameter and pre-drill pilot holes.

Otherwise, the screws will remain loose.

In summary, the screw issues with KALLAX hinges are mainly caused by the material properties of the shelving unit. MDF or particleboard are not ideal for dynamic stresses such as frequent tilting.

Some systematic recommendations:

- Always use threadlocker with screws
- Consider slightly enlarging drill holes and using larger screws
- If possible, use screws with deeper threads or special fasteners
- For a professional solution, use threaded inserts or wooden dowels

This is the key advice. You should use a medium-strength threadlocker that can be removed with tools if needed but will not loosen during normal use. This effectively prevents loosening.

Hello, I really agree with you, I have experienced the same problem myself.

It’s very annoying, especially because you don’t always immediately know what the cause is – the screws, the material, or the installation?

I tried using screws with some rubber washers to introduce damping, and that helped so that the screws don’t loosen quite so quickly.

The idea of tightening carefully also seemed very sensible to me, since too much force can actually cause more harm than good.

Exactly, you don’t want to end up not being able to remove the doors at all. So don’t use anything too strong.

Thanks to everyone for the tips! 🙂
