#2 Phillips screwdriver with a 4-inch round shank and cushion-grip handle for comfort and torque
The Klein Tools 603-4 is a #2 Profilated Phillips screwdriver built for technicians who need a reliable hand driver for everyday fastening tasks. Its precision-machined tip engages fasteners cleanly to reduce cam-out and deliver consistent torque.
The 102 mm round shank reaches recessed screws in electrical boxes, junction enclosures and terminal strips without needing an extension. A cushion-grip handle with internal flanges anchors the blade against twisting, freeing the user from fighting handle rotation during high-torque applications.
Special heat-treated shafts and premium chrome plating resist wear and corrosion across repeated jobs, while the Tip-Ident marking lets crews grab the right driver instantly. The driver meets applicable ASME/ANSI specifications, so performance remains predictable over long service life.
