Arrowmax am-419150 Limited Edition 5.0 X 110mm Allen Key  [am-419150]

Tuning-grade Allen key for setup adjustments

The Arrowmax am-419150 Allen Wrench is a limited edition tool intended for scale RC applications where precise access to hex screws is required. The 5.0 X 110mm marking identifies a 5.0mm tip paired with a 110mm shaft to reach deeper fasteners while allowing fine control.

It is useful during setup and tuning sessions, providing dependable engagement with 5.0mm hex bolts on items like chassis plates, suspension linkages, and motor mounts. The added length is helpful when you need to reach components while observing setup changes in real time.

For best results during tuning, seat the 5.0mm tip fully, use small, steady torque adjustments, and avoid side loading that could damage the screw head or tip. The tool's reach makes incremental changes to gearing or suspension positions easier to perform without disturbing surrounding components.

Keep the wrench clean and stored separately to avoid tip damage; a quick wipe after each tuning run and a secure storage spot will preserve consistent fit and prevent rounding of screw heads during repeated adjustments.
