Magnetized tips make starting and retrieving screws in hard to reach areas easier. The tri lobe handles are easy to wipe clean and the extruded translucent acetate used for the handles is specially formulated to provide superior impact and UV resistance. Blades are chrome plated for superior resistance against rust and corrosion. Color coding (blue for Phillips,; red for Slotted, clear for Torx and multicolor for nutdrivers) makes driver selection simple.
