Arrowmax am-419140 Precision 4.0 x 110mm Hex Wrench Limited Edition for RC upkeep  [am-419140]

Precision hex wrench for careful model maintenance

The Arrowmax am-419140 Allen Wrench is a compact, RC-scale hex driver specified as 4.0 x 110mm and released as a limited edition. It is intended for use with standard RC hex screws and fasteners, giving a defined tip size and reach for repeatable adjustments during setup and repair.

Its consistent tip profile and extended 110mm reach make it suitable for tasks like securing electronic mounts, fine-tuning servo linkages, inspecting motor fasteners, or making measured setup changes. The 4.0mm tip matches many common hex screw heads used on radio-controlled models.

Care guidance: ensure correct tip seating before tightening, work on a secure surface to protect fastener heads, and store the wrench clean and dry to preserve tip accuracy. Use only for hobby-scale applications.
