The Ultimate Intersection Piece

The Brick, Round 2 x 2 with Pin Holes (17485) is a powerful hybrid element that bridges the gap between System bricks and Technic functionality. This cylindrical brick features standard studs on top and bottom, but its true value lies in the four Technic pin holes spaced evenly around its sides. This design allows it to act as a central hub, enabling builders to attach components in four different horizontal directions simultaneously.

Mastering SNOT Techniques

For advanced builders, this part is a cornerstone of SNOT (Studs Not On Top) construction. By inserting friction pins or axles into the side holes, you can mount Plates or tiles vertically, creating smooth walls, intricate column details, or complex engine blocks. It effectively allows you to change the direction of building by 90 degrees with a sturdy internal core.

Robotics and Machinery

This element is frequently used in the construction of brick-built droids and mechanical models. It serves as an excellent body or joint segment for custom robots found in sci-fi themes like Star Wars. To fully utilize this piece, make sure you have a supply of half-pins or connector pegs from our Pins & Connectors collection to attach your side assemblies.
