4.0 x 120mm Allen Wrench for RC Models - Arrowmax AM-410140-BG  [AM-410140-BG]

Precision Allen Driver for Models

The Arrowmax AM-410140-BG Allen Wrench is supplied as a 4.0 x 120mm hex driver for use with 4.0mm hex screws found across model chassis and accessories. The extended shaft length aids access to hard-to-reach fasteners while the black golden finish describes the external appearance rather than composition.

It is suitable for standard build work, setup and quick on-venue tuning, helping with duties such as suspension adjustments, servo positioning and chassis checks. The fixed shaft length provides a predictable reach and can reduce wrist strain during repetitive tasks.

Since the maker does not disclose additional material or heat-treatment information beyond the finish, users should verify tip condition prior to delicate tightening jobs and replace the wrench if the tip becomes rounded or damaged.

Keep this 4.0 x 120mm Allen wrench in your tool kit for assembly and setup tasks, and store it dry to protect the tip.
