LEGO® Technic Pins & Connectors

Build secure and functional LEGO® Technic assemblies with pins, axle connectors and joining elements designed for structural and mechanical connections. These small parts are essential for attaching beams, bricks, axles and moving components throughout Technic builds.

LEGO® Technic Pins & Axle Connectors

Technic pins and connectors are used to join structural elements, create pivot points and support moving mechanisms. Different connector types provide either rigid attachment, controlled movement or axle alignment depending on the needs of the build.

• Friction Pins: Ridged pins designed to hold beams and Technic elements firmly together in structural assemblies.
• Frictionless Pins: Smooth pins that allow easier rotation and movement in hinges, steering systems and articulated mechanisms.
• Axle Connectors: Join axles in straight, angled or perpendicular arrangements for drivetrains and mechanical systems.
• Angled & Multi-Direction Connectors: Useful for creating non-linear frames, steering linkages and compact mechanisms.

Connect Technic Beams & Bricks

Use Technic pins to join Technic beams and liftarms into rigid or moving frameworks. They also connect with Technic bricks with pin holes when combining studded construction with Technic structures.

This makes pins and connectors the linking system between many of the main structural parts used in advanced LEGO® Technic builds.

Friction Pins vs Frictionless Pins

Choosing the right pin depends on whether the connection needs to stay fixed or move freely.

• Friction Pins: Best for rigid frames, chassis sections and load-bearing connections where movement is not required.
• Frictionless Pins: Better suited to pivots, steering mechanisms and moving assemblies where parts need to rotate more easily.

Axle Connectors for Drivetrains & Mechanisms

Technic axle connectors extend or redirect rotating shafts within gearboxes, steering systems and powered mechanisms. Straight connectors join axles end to end, while angled and perpendicular connectors help route rotation through more complex layouts.

Combine axle connectors with LEGO® axles and Technic gears when building drivetrains, gearboxes and rotating systems.

Common Uses for Technic Pins & Connectors

• Vehicle Chassis: Secure beams and structural sections together.
• Steering Systems: Create pivots, linkages and movable connections.
• Gearboxes: Support axle routing and modular mechanical assemblies.
• Robots & Machinery: Build articulated joints and complex structural connections.
• Repairs & MOCs: Replace missing connectors or source specific joining elements for custom builds.
