Arrowmax am-429378 Ball Driver Hex Wrench .078 (5/64) X 110mm Limited Edition  [am-429378]

Ball-Point Hex Driver for Tight Access

This Arrowmax am-429378 ball driver hex wrench is an RC-scale hand tool built to reach and engage the small hex screws used throughout model chassis and components. The .078 (5/64) tip and 110mm overall length are taken from the product designation and indicate its use for tight or recessed fasteners on radio controlled models.

As a ball driver style hex wrench, the rounded tip lets you enter screws at a slight angle when alignment is obstructed, which helps when adjusting servo linkages, pinion gears, or other assembly points where direct access is limited. The 110mm shaft adds reach without excessive leverage, keeping fine control during delicate setup tasks.

Use this tool for routine assembly, component swaps, and trackside tuning where reliable engagement with small hex screws matters. It is intended specifically for RC-scale accessories and model maintenance.

Compact, focused, and sized exactly as named, this tool is ideal for builders who require a dedicated .078 (5/64) hex driver for precision RC work.
