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

Compact Ball-Point Hex Driver

The Arrowmax am-429378 ball driver hex wrench is produced as an RC-scale hand tool to reach and engage the small hex screws commonly used across model frames and subcomponents. The .078 (5/64) tip together with the 110mm overall length describe its intended application for recessed or hard-to-reach fasteners on scaled models.

Designed in the ball driver format, the tip profile permits slight angular entry to access screws that are not perfectly aligned, assisting when setting up servo links, adjusting motor pinions, or assembling parts where direct approach is limited. The 110mm shaft gives reach without creating excessive leverage, preserving control for fine tuning tasks.

Apply this wrench for assembly work, part swaps, and during on-track or workshop tuning where consistent contact with small hex screws matters. It is meant specifically for RC-scale maintenance and accessories.

Slim, precise, and matched to the size indicated in its name, this tool serves builders who need a dedicated .078 (5/64) hex driver for accurate model work.
