Technic Bricks | LEGO® Building Blocks with Pin Holes

Build strong hybrid structures with LEGO® Technic bricks. These studded bricks feature integrated pin or axle holes, allowing you to combine traditional LEGO® brick construction with Technic mechanisms, connectors and moving systems.

Unlike Technic beams and liftarms, which are designed for studless structural frameworks, Technic bricks keep the familiar studded brick format while adding side connection points for pins and axles. For the wider mechanical parts range, explore our LEGO® Technic parts collection.

LEGO® Technic Bricks with Pin & Axle Holes

Technic bricks are useful when a build needs both standard stud connections and Technic functionality. Their integrated holes make it possible to attach pins, axles, connectors and mechanical assemblies directly to a studded structure.

• Technic Bricks with Pin Holes: Ideal for attaching beams, connectors and moving assemblies to studded builds.
• Technic Bricks with Axle Holes: Useful for supporting rotating axles, steering systems and compact mechanisms.
• Multi-Hole Technic Bricks: Longer bricks provide several aligned connection points for chassis, frames and machinery.
• Specialised Technic Bricks: Angled and modified designs help solve more complex structural or mechanical connections.

Why Use Technic Bricks?

• Hybrid Connectivity: Combine normal studded LEGO® construction with Technic pins, axles and mechanical components.
• Strong Mounting Points: Create secure side connections for mechanisms, frames and moving assemblies.
• Precise Alignment: Integrated holes help keep axles, pins and connected Technic elements accurately positioned.
• Compact Mechanical Builds: Add Technic functionality without replacing an entire studded section with liftarms or frames.

Technic Bricks vs Technic Beams

Technic bricks and Technic beams can perform similar structural roles, but they use different building systems.

• Technic Bricks: Studded elements with pin or axle holes, best for hybrid builds that combine classic bricks with Technic mechanisms.
• Technic Beams & Liftarms: Studless structural elements designed for lightweight frames, chassis and reinforced Technic assemblies.

If you are building a mainly studless frame, browse our LEGO® Technic beams and liftarms. If your project uses standard bricks but needs mechanical connection points, Technic bricks are usually the better choice.

Connect Technic Bricks with Pins, Axles & Gears

Use Technic pins and connectors to join Technic bricks to beams and other structural elements. Axle-hole bricks can also support LEGO® axles in steering systems, drivetrains and rotating mechanisms.

For gearboxes and powered mechanisms, Technic bricks can provide rigid mounting points that help keep Technic gears and axles correctly aligned.

Common Technic Brick Sizes & Uses

Different Technic brick configurations suit different types of builds. Common examples include:

• 1x1 Technic Bricks: Compact connection points for axles, pivots and small mechanisms.
• 1x2 Technic Bricks: Versatile parts for small assemblies, supports and pin connections.
• Long Technic Bricks: Useful for chassis rails, reinforced walls and multi-point mechanical mounting.
• Bricks with Axle Holes: Designed for rotating shafts, steering parts and drivetrain components.
