Hello everyone,
I bought a Billy bookshelf from Ikea and I want to slightly enlarge the existing screw holes because I plan to use thicker screws for greater stability. I’m wondering what the best way is to do this without damaging the wood or compromising the strength of the connection.
What are the best tools and methods to carefully but effectively enlarge the drill holes in the thin wood of the Billy shelves? I’m especially interested in tips on what to pay attention to, such as wood type, drill bit size, drilling depth, and so on.
Thanks in advance for your advice and recommendations!

Regarding the screw type: I was thinking of switching from the usual 3.5 mm screws to 4.5 mm or 5 mm screws to get more stability. The shelf is made of standard particleboard, about 16 mm (0.6 inches) thick.
Ultimately, I want the screws to hold firmly but without damaging the wood.
What do you think about the risk of damaging the material with such a small increase in screw diameter? One more question: Would countersinking the screw holes be advisable if I use larger screws, or is that risky because of the veneer surface?

It’s great that you want to make the shelf more stable! :-)
I would say that if the screws are only 1–1.5 mm (about 0.04–0.06 inches) larger, the risk is manageable. But drill slowly and watch the area carefully to see if the wood starts to split!
A countersink can help if you want the screw heads to be flush or recessed. Just be especially careful not to damage the veneer, as that not only looks unattractive but can also reduce stability.
Maybe try it first on an inconspicuous piece of wood to get a feel for it!

A few additional notes on countersinking:
Countersinking is always a delicate matter with veneered or melamine-coated surfaces. If the edge of the countersink is too deep or unevenly done, the surface will wear out faster and may even chip. This means:
- Use a high-quality countersink bit
- Countersink lightly and only as deep as needed for the screw head to sit flush
- If necessary, smooth the edge on the surface with fine sandpaper
If the shelf has a load-bearing function, it’s advisable to place the countersinks indirectly or in areas that bear little stress.
Another consideration: If you increase the screw size significantly, the shelf panel itself can be damaged, as chipboard or MDF tends to splinter or tear out, especially when drilling near edges. Please carefully check exactly where you plan to place the screws.

How do you see the risk of damage to the material with such a small enlargement?As long as you don’t drill much larger, the risk is low. It is important to use a sharp drill bit and drill slowly to avoid splintering.
