Technic Brick 1 x 16 with Holes 3703

Construct rigid frames and mechanical assemblies with the LEGO® Technic brick 1 x 16 with holes. Listed under MPN 3703, this structural element combines classic stud-based geometry with standard Technic connection points, making it a reliable foundation for larger models.

Structural geometry and dimensions

Measuring 16 studs across the top surface, this brick includes 15 cross-drilled pin holes along its length. The side openings align with standard Technic pins, axles, and connector pieces, allowing builders to attach perpendicular beams, bracing members, and gear mechanisms alongside standard studded elements.

Mechanical applications and framing

The long single-piece profile provides high longitudinal stiffness for vehicle chassis, crane booms, bridges, and heavy framework. To discover complementary beams, connectors, and specialty components for your build, explore the LEGO Technic parts range.
