4.0 x 150mm Flat Head Hobby Screwdriver by Arrowmax - am-439140  [am-439140]

Tool for setup and trim work

Arrowmax am-439140 is a 4.0 x 150mm flat head screwdriver offered in a limited run for model hobbyists, sized to get into narrow assembly points. The model label specifies the tip width and shaft length to help you judge fit and reach on slotted fasteners used across model components.

It excels where a straight slotted tip and extended shaft let you access recessed screws around chassis areas, suspension towers, gearbox plates and servo mounts. The design suits hand-held use for setup tweaks, tuning sessions and everyday servicing of radio-controlled vehicles.

Align the tip directly in the screw slot and turn with a smooth, controlled motion to prevent cam-out; the 150mm shaft makes it easier to reach deep fixes without dismantling nearby parts.
