Looking to add some dynamic movement or mechanical detail to your LEGO® creations? The Arm Mechanical, Exo-Force / Bionicle part could be just what you need.
This sleek, jet-black element is designed as a thin mechanical arm, often used in Exo-Force and Bionicle sets to create articulated limbs or robotic features. Its slim profile makes it ideal for building intricate mechanisms, extending minifigure accessories, or adding realistic jointed appendages to custom robots and sci-fi models. Whether you’re upgrading a minifigure with a mechanical arm or assembling a complex build, this part brings flexibility and technical flair to your next project.
