The LEGO® Technic Modified Brick 2 x 2 with Pin Hole and Rotation Joint Socket (Part 48169) is designed for articulated Technic builds, rotating connections, and movable structures. Its combination of a Technic pin hole and rotation joint socket makes it useful for mechanisms that need controlled movement, strong connection points, and compact structural support.
Technic Brick for Rotation Joints and Movement
Part 48169 is commonly used when a build needs a pivoting or rotating connection. The integrated socket works with compatible rotation joint ball connectors, while the Technic pin hole allows the part to connect into larger Technic frameworks, brackets, and mechanical assemblies.
