Connector (102 parts)

A wide range of parts with pin and axle connectors that can be used to connect Technic parts together.

Unlike LEGO bricks which usually have a stud and antistud connection, most Technic parts can not connect with each other without using a separate part to hold them together. These parts are broadly called connectors, with two common connection types.

Axles are held in place with bushings (bush) or using parts with an axle hole connection.

Pins stay put when attached to a pin hole. Smooth pins can rotate freely when attached to a pin hole, whereas friction pins are harder to remove and can not spin very easily.
