ᐅ Are there specific screws that provide greater stability for BILLY shelves?

Hello everyone,

I am currently looking into the stability of Billy shelves, especially concerning the screws used. Are there specific screws or types of screws that can be used instead of the original ones to significantly improve the stability and load-bearing capacity of the shelves?

My main focus is whether this can make the shelf more resistant to stress or twisting without the need for additional reinforcements or modifications.

I would appreciate advice on suitable screw types, dimensions, materials, and any experiences with alternatives that have proven effective.

The standard BILLY shelf screws are usually thin and short, which is sufficient for the original design. However, if you want to increase stability, it is advisable to use screws made of alloy steel with a larger diameter (e.g., 4 mm (0.16 inches) instead of 3 mm (0.12 inches)) and longer length to achieve better anchoring in the cabinet.

The choice of screw type is also important: coarse-thread chipboard screws improve grip in wood-based materials. Alternatively, galvanized or stainless steel screws can be used to prevent corrosion, which is beneficial for long-term durability under higher loads.

The best option is 4x40 mm (1.6x1.6 inch) chipboard screws made of hardened steel. They are more durable than the original ones.

Hey,

I upgraded my BILLY shelves with slightly thicker stainless steel screws. It worked really well, and now the shelf stays stable even with a bit of wobbling! 👍

The original screws are quite basic – adding stronger screws makes the shelf feel much more solid. Sure, it takes a bit of effort, but it’s totally worth it for a sturdy setup. 🙂

As an addition: It is also important to consider the direction of the load when screwing. For shelves like BILLY, which primarily bear vertical loads, the focus should be on screws that engage optimally along the shelf supports.

A practical recommendation is to use countersunk screws with a wide bearing surface to increase load capacity and cause less damage to the material.

This is exactly the point that should be the focus when choosing replacement screws for improved stability.

From my experience, the material of the shelf carcass is often the limiting factor. Even the best screws won’t help if the particle board is too thin or porous. Therefore, it is also advisable to reinforce shelves modularly – for example, with metal brackets – when planning for extremely heavy loads.
