Yokomo YT-N70W Works Wrench 7.0mm Nut Driver — Carbide-tip box wrench for RC wheel nuts  [YT-N70W]

Box wrench for RC wheel nuts

This 7.0mm box wrench from Yokomo's Works Wrench line is a compact, RC-scale tool designed specifically for turning wheel mounting nuts on model cars. The key contact point is a high-precision carbide tip that focuses on repeatable engagement with nut flats to reduce slippage during tightening and loosening.

The wrench uses an aluminum grip shaped for a comfortable hold and low weight, helping to reduce hand fatigue during frequent wheel changes and setup work. Its box-end form keeps the tool seated on the nut during rotation, which is useful when removing or fitting wheel nuts quickly in pit checks or routine maintenance.

For installation and tuning tasks, use the 7.0mm box end to seat fully over the nut before applying torque, keep the carbide face clean of debris for consistent contact, and avoid levering from awkward angles that can round nut edges. The tool is an accessory for RC wheel and wheel nut service, not intended for any full-scale vehicle work.
