Robinson is a common mishearing of Robertson, the square-recessed screw drive this bit is ground to fit; this bit is the #2 size in red, sized for screws #8 to #10.
A robertson bit resists cam-out because its tool-steel square-recess tip seats firmly in the screw's matching recess, holding position under torque instead of slipping out the way a slotted or Phillips drive can.
The tips are tool steel and the shanks are powder-coated carbon steel, color-coded yellow, green, red or black by drive size.
They have a 1/4" hex shank, so they fit standard drills, drivers and hand drivers without needing an adapter.
