LEGO Part Plate 4×4 Light Bluish Gray

LEGO Part 3031 – Plate 4×4 is a foundational building element used in countless official LEGO sets and MOCs. This 4×4 stud plate offers a sturdy, flat surface ideal for building bases, floors, platforms, roofs, vehicles, and structural reinforcements. With its square shape and low profile, it’s perfect for adding stability and layering without increasing height like bricks would.

Often used in LEGO City, LEGO Creator, LEGO Technic, and LEGO Modular builds, the 4×4 plate provides excellent versatility when building mechs, buildings, terrain, and custom models. Its uniform size makes it a go-to piece for SNOT (Studs Not on Top) techniques, tile layering, and as a connector between different sections of a build.

Whether you’re reinforcing a structure, building a smooth platform, or spacing out mechanisms, the LEGO 4×4 plate is a core piece in any builder’s collection.
