LEGO® Technic Bricks

LEGO® Technic bricks combine a traditional studded brick format with holes for Technic pins, axles and mechanical connections. These structural elements help builders connect standard brick construction with moving assemblies, reinforced frameworks and functional mechanisms. Explore different sizes and hole layouts for vehicles, machinery, supports and custom engineering projects.

Studded Bricks for Mechanical Building

Unlike smooth Technic beams, Technic bricks retain studs across the top while adding connection holes through the sides. This makes them useful for models that combine standard brick walls and layers with axles, pins or rotating components.

• Pin-hole bricks: Connect frames, supports and articulated sections.
• Axle-hole bricks: Support rotating shafts, wheels and mechanical assemblies.
• Long Technic bricks: Reinforce chassis, frameworks and larger structural sections.
• Compact Technic bricks: Add mechanical connection points within tighter spaces.
