Quick Slicks Hex Driver with 0.9mm (.035") tip. Features knurled handle with spinner top that fits comfortably in the palm of your hand. Includes high-quality 0.9mm (.035") hex tip that fits M2 set screws commonly used to secure 1:32 slot car wheels and gears from manufacturers such as CB Design, Slot.It, Scaleauto (1:32), Sideways, MRSLOTCAR, and Sloting Plus (some).
For builders/racers who glue/true their tires, note the Quick Slicks hex tip design has no taper or "steps" so it will not enlarge or tear the tire's set screw access hole.
Replacement tips sold separately.
