The Arrowmax AM-420120-BG Ball Driver Hex Wrench is a compact 2.0 x 120mm tool aimed at hobbyists who need precision in tight assemblies. Its black golden surface provides a neat look while standing up to regular bench use.
The ball driver geometry allows you to approach hex screws from off-axis positions, making it easier to reach recessed fasteners or awkward mounting points typical on RC models. The 2.0mm head handles delicate tweaks and set-screw adjustments.
The honeycomb-inspired body keeps the overall weight down while maintaining a sturdy feel. That balance helps control when performing multiple small adjustments during setup or maintenance.
