Arrowmax am-420263-bg Ball-End Hex Wrench for On-Track Tuning .063 (1/16) 120mm  [am-420263-bg]

Ball-tip hex driver for tight access

This Arrowmax am-420263-bg ball driver is an RC-scale hex tool sized for .063 (1/16) hex screws with a 120mm shaft and a ball-end profile, finished in black and golden tones. The ball tip provides a modest entry angle that helps maintain engagement when reaching awkwardly placed screws.

Made as a hand tool for model car work, the driver is useful for assembly, setup changes, and precise adjustments to parts like suspension links and servo horns. The 120mm length gives the reach needed for recessed fasteners without sacrificing control.

Use the driver to align screws during installation, apply careful snugging, and perform quick track-side tune-ups where a slight ball-end offset aids speed and accessibility. Clean and store the tool after use to protect the tip geometry and finish.
