Arrowmax am-419140 4.0 x 110mm Allen Driver Limited Edition hex tool for RC tuning  [am-419140]

Limited edition Allen driver built for RC tuning tasks

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.

The tool is useful when you need predictable torque for jobs like tightening mounts, adjusting steering linkages, checking gearbox bolts, or making setup tweaks at the field. Its 110mm length helps reach recessed fasteners while the 4.0mm tip aligns with common hex heads across many models.

Practical care notes: check fit before applying torque, perform work on a steady bench to avoid rounding heads, and keep the wrench free of dirt to retain accurate engagement with hex screws. Not intended for heavy industrial use.
