Hello everyone,
I am planning to use some heavy BILLY shelves from IKEA, mainly to store books and files neatly. Since I am unsure which screws are best suited for mounting and reinforcing the shelves, I would like to ask specifically here:
Which screws are recommended for heavy BILLY shelves if I want to significantly improve their load-bearing capacity? It is important to me that the screws provide optimal support both for the shelf supports and when fixing the unit to the wall, without damaging the material.
Are there specific types or sizes of screws you would recommend? And what criteria should I consider when choosing, especially regarding avoiding material cracking or slipping?
Thanks in advance for your advice!

Thanks for the very helpful tips so far! I would like to add or better understand two things:
How exactly does assembly adhesive help here? I’m concerned whether it might affect the screw connection or not.
And regarding angle brackets:
Could someone provide specific product recommendations, for example, which sizes or thicknesses have proven especially effective for BILLY shelves? Or would simple furniture brackets be sufficient?
Many thanks!

Assembly adhesive can additionally improve the load-bearing capacity of screw connections, as it mainly prevents shear forces.
It prevents wobbling or slight shifting of the panels, which reduces continuous stress on the screws. This extends the lifespan of the connection. However, the adhesive does not replace the mechanical connection with screws; it only complements it.
Regarding angle brackets:
Simple steel furniture angle brackets with a thickness of 2-3 mm and dimensions around 40x40 mm or 50x50 mm (1.6x1.6 inches or 2x2 inches) have proven effective and are easy to install.
For particularly heavy loads, a version made of electrolytically galvanized steel with larger dimensions (e.g., 60x60 mm or 80x80 mm (2.4x2.4 inches or 3.1x3.1 inches)) is recommended. It is important that the brackets are screwed to the wall and the shelf with multiple fasteners.
Summary: For standard reinforcements, sturdy furniture angle brackets from hardware stores are sufficient; for heavier loads, better to use reinforced brackets from specialized suppliers.

Assembly adhesive can be used as a supplement but does not replace screws. Furniture brackets with a thickness of 2–3 mm (0.08–0.12 inches) are sufficient for most BILLY shelves.
Important: Always pre-drill the screws and use wall anchors appropriate for the wall type.
In short, screws plus anchors plus brackets = stability.

warrenka573 Dec 2023 07:58This topic was very important to me as I filled several shelves with textbooks and wanted to avoid any unpleasant surprises.
In the end, I chose 4x40 mm (roughly 1.5x1.5 inch) galvanized chipboard screws for the shelves and reinforced the unit with additional 80x80 mm (approximately 3x3 inch) corner brackets on both the shelf and the wall. The wall attachment was done using 8x80 mm (about 0.3x3 inch) heavy-duty anchors in brick walls.
My advice to everyone: take your time during assembly, drill pilot holes carefully, avoid over-tightening the screws, and invest a bit more in your anchors and screws.
Another thing that helped me was fully securing the back panel of the shelf with double-sided tape, which helped prevent lateral wobbling.
