2mm Steel Round Shaft Axles for DIY Robotics – Pack of 5

Build Moving Robotics and Mechanical Projects

The 2mm Steel Round Shaft Axles are versatile mechanical components designed for DIY robotics, model vehicles, STEM activities, and engineering experiments.

With an approximately 2mm diameter, these round steel shafts can be used as axles for compatible miniature wheels and as rotating shafts in a variety of mechanical projects. They are useful for building small DIY cars, robotics chassis, pulley mechanisms, wheel-and-axle systems, and experimental moving models.

Compared with improvised materials such as wooden sticks, toothpicks, or plastic straws, steel shafts provide a more rigid and consistent component for mechanical prototypes and educational projects.

These axles are particularly useful for students learning about rotational motion, wheel-and-axle mechanisms, drivetrain design, mechanical power transmission, and structural engineering.

Whether you are building a manually powered vehicle, a motorized model, a simple robotics chassis, or a classroom mechanical experiment, these compact steel shafts provide a practical foundation for your project.
