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

Hand Tool for Recessed Hex Screws

This Arrowmax am-429378 ball driver hex wrench is an RC-scale hand tool engineered to access and engage the small hex screws found in model chassis and componentry. The .078 (5/64) tip and 110mm overall length, drawn from the product designation, define its purpose for tight or recessed fasteners on RC models.

The ball driver tip profile allows entry at a slight angle to engage screws that are offset or partially obstructed, which is useful when adjusting servo linkages, fitting motor pinions, or lining up other precision parts in confined spaces. The 110mm shaft provides reach while keeping leverage moderate for controlled adjustments during fine tuning.

Employ this tool for assembly, component replacements, and trackside tuning where secure engagement with small hex screws is necessary. It is designed exclusively for RC-scale maintenance tasks and accessories.

Accurate and purpose-built to the nominal size in its name, this driver is suited to modellers who need a reliable .078 (5/64) hex driver for precise jobs.
