This Nut Driver is greatly handy for tightening the 2mm nuts and 2mm lock nuts which are often used on Mini4WD machines. Its compact size and easy gripping handle helps keep the tool steady, especially when you are using it with a plus ( ) driver at the same time. The bit is made of strong chrome vanadium steel.
