Hello everyone,

I have an older Billy shelf unit, and some of the screw holes used to secure the shelves have become a bit worn out. As a result, the screws no longer hold properly, and the shelves are not stable anymore.

My question is: What methods are there to effectively reinforce the screw holes of a Billy shelf unit to make the furniture stable and load-bearing again?

I am mainly looking for practical and durable solutions, ideally methods that can be done with minimal effort and without special tools.

Does anyone have experience or recommendations on the best way to approach this? Thank you!

As an additional tip:

Another practical suggestion is to apply a drop of construction adhesive or superglue into the freshly drilled hole before screwing in the screw. This increases the screw’s hold in the wall plug (anchor) without stressing the wood.

However, it is important not to apply too much adhesive to avoid gluing the screw threads.

This way, a solid connection can be achieved under typical household loads.

I also recommend using wood filler combined with pilot holes and the appropriate wood screws.

After the wood filler has hardened, be sure to carefully sand it down with fine-grit sandpaper so the screw can be inserted cleanly.

I’ve had good results with this method on several shelves. 🙂

Wood dowel method with PU or photovoltaic adhesive

I always use PU glue (e.g., Titebond Polyurethane) for similar repairs. It is waterproof and slightly more flexible than regular wood glue, which sometimes holds better on panel materials.

It is important to have the hole as dry and dust-free as possible, as already mentioned here.

Great, thanks to everyone for the detailed answers! The method using wooden dowels and wood glue currently seems the most practical to me.

I will get the materials before the weekend and then proceed with the repair step by step.

Your tips on securing, drying times, and preferably small drill bit diameters for the new screw holes are very helpful.

I will report back as soon as I have some initial experience and if any further questions come up.
