Precision hex key for RC adjustment

The Arrowmax AM-410278-BG Allen Wrench is a 5/64" (0.078") hex tool with a 120mm shaft, built for careful adjustment work on RC models. It provides a straight slim profile for working in narrow assemblies and around tight brackets.

Appearance and handling

The black and golden colourway gives a clean workshop appearance while the honeycomb handle pattern helps maintain a secure hold. The form factor aims to combine a slender tip with a comfortable driving surface for repeatable results.

Use cases and care advice

This wrench is suited to small fasteners on linkages, servo horns and mountings, helping to avoid stripped heads. Keep screws and tip clean and apply measured torque to preserve threads and fastener integrity.
