Technic Pin 3/4 (32002)

The LEGO® Technic Pin 3/4 is a compact connector designed for secure mechanical assemblies in LEGO® Technic models. Part 32002 combines a short friction-fit connection with a compact profile, making it useful wherever standard Technic pins would occupy too much space. Its simple design allows reliable connections between liftarms, connectors and other Technic elements while maintaining smooth, accurate alignment.

LEGO® Technic Pin 3/4 Connector

This connector features a reduced-length body with a friction section that provides a firm grip inside Technic pin holes. The shorter design makes it particularly useful for compact mechanisms, closely spaced assemblies and structural reinforcement where limited clearance is available. Its size also helps reduce interference between moving components in more intricate Technic models.

The Technic Pin 3/4 is widely used throughout LEGO® Technic sets for creating stable connections while preserving compact dimensions. Builders frequently use this part when assembling frames, steering systems, suspension components and internal mechanical structures.
