This Arrowmax am-420263-bg ball driver is an RC-scale hex tool sized for .063 (1/16) hex screws with a 120mm shaft and a ball-end profile, finished in black and golden tones. The ball tip allows a slight angle of entry so you can access screws set into tight locations without compromising the hex socket.
Intended as a hand tool for model car use, the driver assists with assembly, maintenance, and accurate component adjustments such as suspension link settings and servo horn positioning. The 120mm shaft reaches into deeper mounting points while giving controlled leverage for delicate turns.
Employ it to guide screws during fitting, to apply final snugging with care, and for small adjustments while working on the bench or at the track. After use, clean off debris and store the driver to keep the tip profile and finish protected.
