LEGO® Ball Joint Brick Set – 6x Dark Bluish Gray (3x Ball + 3x Socket)
The Foundation of Strong, Posable Joints
Build the articulated creations of your dreams with this essential six-piece set of LEGO® Technic ball and socket bricks. This pack contains three ball bricks and three matching socket bricks in dark bluish gray, giving you everything you need to create three complete, heavy-duty joints. The integrated axle holes in each brick allow you to reinforce your pivots for maximum stability.
This set is a fundamental starter pack for anyone exploring our Technic Ball Joints & Sockets collection.
Engineered for Ambitious Builds
These 2x2 bricks are the go-to solution for creating the load-bearing joints needed for large-scale figures and complex machinery. The axle hole is a critical feature, allowing you to run an axle through the center of the joint to prevent it from pulling apart under stress—a must for playable, durable models.
Creative Building Applications:
- Mech and Robot Skeletons: Form the strong shoulder, hip, and knee joints for large, posable figures.
- Large-Scale Creatures: Design the articulated limbs and necks for brick-built dragons or dinosaurs.
- Heavy-Duty Suspension: Engineer robust suspension systems for large, off-road vehicles.
- Functional Robotic Arms: Create multi-jointed arms for cranes or robotic walkers that can support weight.
Combine these joints with a sturdy framework built from our Technic beams and secure everything in place with Technic pins and connectors.
