This is a 5.5mm box-style nut driver from Yokomo's Works Wrench line, built as an RC-scale accessory for precise nut turning on model cars. The tool is specified for use with 3mm nuts and intended for setup and routine maintenance tasks in RC chassis and wheel work.
The driver uses a high-precision carbide tip to engage nut flats cleanly, reducing the chance of rounding small fasteners during tuning or assembly. The aluminum grip provides a comfortable hold and a lightweight overall feel to reduce hand fatigue during repeated adjustments.
Use this driver when adjusting suspension mounts, wheel nuts, or other 3mm fasteners where a compact box wrench gives better torque control and repeatable seating than a generic wrench. The design emphasizes precision and ergonomics for workshop and track-side setup duties on RC-scale models.
