When standard metric hardware screws don’t fit a crib even though they appear to be the correct size it usually means the crib was designed to only use manufacturer-specific fasteners, not interchangeable hardware-store screws.

In the case of Brio baby cribs, some models use screws that are labeled as metric (such as M6) but are made with a different thread pitch or thread profile than standard ISO metric machine screws. Because of that, off-the-shelf metric screws may look correct but will not seat properly and should not be forced.

If you’re missing original crib screws and standard metric hardware does not fit:

Avoid forcing or modifying screws to make them fit.

Avoid substituting "close enough" hardware, even if the diameter and length appear similar.

Avoid re-tapping or altering threaded holes in crib components.

Cribs are safety-critical products, and proper assembly depends on hardware that exactly matches the manufacturer’s original specifications.

The safest next step is to identify the crib model and original hardware type and look for replacement screws that are specifically listed for that crib, or that have been verified to match the original thread pattern. When asking for help or parts, providing clear photos of the crib label and the original screws (if any are available) can help others identify the correct hardware.

If the correct replacement screws cannot be located, or if the crib cannot be assembled exactly as designed, it’s best to pause assembly and avoid use until proper parts are found.
