Technic Brick 1 x 2 with Joint Socket 80431

Create compact articulated connections with the LEGO® Technic Brick 1 x 2 with Rotation Joint Socket 80431. This modified brick combines a small studded footprint with an integrated socket, providing a useful connection point for compatible Technic rotation-joint ball elements.

Compact Technic Rotation Joint Socket

Part 80431 is particularly useful when a model needs articulation without taking up much building space. The socket allows a compatible ball-joint element to pivot while the 1 x 2 brick body can be incorporated directly into a studded structure.

LEGO® 80431 Features

• Modified Technic brick with a 1 x 2 footprint
• Integrated rotation-joint socket
• Designed for compatible Technic ball-joint connections
• Two upper studs for standard studded construction
• Compact design for articulated mechanisms and models

Useful for Mechs, Creatures and Moving Builds

The small footprint makes this socket element useful for poseable robots, mechs, brick-built creatures and adjustable machinery. It can also provide articulation for vehicle components or other custom mechanisms where a larger joint assembly would take up too much space.
