ᐅ Which types of screws are most suitable when a BILLY unit is loaded?

RegiloHello everyone,
I am currently looking into which types of screws are particularly suitable when loading a BILLY bookshelf from IKEA or, for example, reinforcing it to achieve a higher load capacity. It is clear that simple wood screws quickly reach their limits as the load increases, but what alternatives make sense?
I am especially interested in screw types that provide a better grip with the thin particleboard and remain stable over time, even when the shelf carries a lot of weight or is subjected to lateral forces. Are there specific screw heads, materials, or thread designs that are especially recommended in such a scenario?
I look forward to your experiences and tips!

Regarding the question of which types of screws are particularly suitable for load-bearing BILLY shelves: chipboard screws with partial threading are generally ideal, as they facilitate penetration into the thicker material while providing strong grip in the thinner shelf wood.
Material: galvanized steel or stainless steel is recommended due to corrosion resistance.
Head: countersunk heads work well to ensure the screw sits flush and does not damage the surface.
Alternatively, Forstner wood screws can be recommended if higher load capacity is required. The thread should be as fine as possible to prevent tearing out.
When reinforcing, the use of dowels or metal brackets with screws can also be a practical addition.

Regarding the type of screw for a load-bearing BILLY shelf, I would like to elaborate a bit more. The most important factor is choosing a screw type that is compatible with the chipboard or wood fiber structure of the shelf.
Generally, chipboard screws are ideal since they are specifically designed for chipboard and rough sawn surfaces. Their fine, partial threads combined with a wood thread section provide good grip in thin layers, while the screw pulls tight and prevents loose connections.
Additionally, I recommend stainless steel screws when high durability and corrosion resistance are required— for example, if the shelf is placed in rooms with high humidity.
Concerning the screw head: countersunk screws are perfect for achieving a flush surface that will not obstruct or get damaged later. There are also pan head screws, which sit slightly above the surface, but this is often a matter of personal preference.
An alternative would be so-called furniture construction screws with an extra-long shank length and an optimized thread design for chipboard. These help create a stronger connection, especially if you want to reinforce the shelf afterward.
Not to be forgotten: for higher loads, additional reinforcements with metal brackets or dowels should be considered. However, it is very important to check the exact dimensions and material thicknesses of the BILLY shelf before purchasing, to choose screws with the appropriate length and diameter.
One more question for Regilo: What type of load do you specifically mean? Is the shelf tilted, is weight mainly placed on individual shelves, or are there lateral forces?

Regarding the type of load: The shelf stands upright and is intended primarily to hold heavy books and binders, so mainly a strong vertical load on the shelves. Additionally, occasional lateral forces may occur, for example, when removing items from the shelf or bumping into it. For stabilization, I have also considered brackets, but my question really focuses on screws that provide the highest possible tensile and compressive strength by themselves.
The shelves and sides are made of thin particle board (about 1.8 cm (0.7 inches)), so the screw type should fit cleanly and minimize the risk of splitting.
Thanks again!
