This Arrowmax am-439140 item is an RC-scale flat head screwdriver sized 4.0 x 150mm in a limited edition run, intended for precision work on model components. The name encodes the tip profile and shaft length, which defines the reach and contact area for slotted fasteners used on many model parts.
Use it where a straight slotted tip and longer shaft help access recessed screws in chassis, shock towers, gearbox covers, servo mounts and other assemblies. The tool is presented as a handheld craft screwdriver for routine maintenance, tuning and small repairs on radio-controlled models.
Keep the tip aligned with the screw slot and apply steady torque to avoid cam-out; the 150mm shaft helps reach tight or deep mounting points without removing adjacent components.
