The Klein Tools 603-4 is a #2 Phillips screwdriver with a precision-machined tip, a heat-treated and chrome-plated blade, and Klein’s Cushion-Grip handle. The blade anchors inside the handle using Klein’s double-flange system.
A precision-machined Phillips tip seats fully inside the screw head and reduces cam-out — the moment where the driver climbs out of the fastener under load and chews up the head. Chrome plating on the blade resists corrosion and jobsite abuse. The double-flange blade anchoring is the difference between a driver that delivers real torque and one that loosens or spins inside the handle after a few months; Klein’s handles are molded around the flanges instead of press-fit, so the blade can’t work loose. Cushion-Grip handles deliver more torque with less hand fatigue. Meets or exceeds applicable ASME / ANSI specifications.
A core daily driver for electricians, appliance techs, and anyone who spins #2 Phillips fasteners for a living.
Per the Amazon listing, the 603-4 is Manufactured and assembled in the USA. Klein Tools has been a family-owned American hand-tool manufacturer since 1857.
