Arrowmax AM-150140 Nut Driver 4.0 x 60mm Hollow Aluminium Nut Driver  [AM-150140]

Tool overview

The Arrowmax AM-150140 is an RC-scale 4.0 x 60mm nut driver built for routine model maintenance and tuning. The driver pairs a hollow anodised aluminium handle with machined spring steel tips to balance light weight and torsional durability, while a clear size indication ring helps prevent size mix-ups during pit work.

Design highlights include a hard-anodised finish on the aluminium handle for surface wear resistance, a non-slip hollow grip to reduce hand fatigue, and rotating aluminium end caps that let the tool sit comfortably in the palm while you turn the shaft. The machined spring steel tip is shaped to hold a 4.0mm nut securely so you can place and tighten hardware with minimal wobble.

Use this nut driver for small-scale RC tasks such as tightening wheel nuts, servo mounts, and chassis hardware where a compact 60mm shaft provides reach without excessive leverage. The tool is purpose-made for hobby-grade RC models and is not intended for full-size vehicle use.
