Keystone Tip Square Shank Screwdriver

The Klein Tools 600-4 is a heavy-duty hand screwdriver built for professionals who need maximum torque on slotted fasteners. Its square shank allows wrench-assisted turning for stubborn screws. The bolster reinforces the shank to withstand hard use on job sites. It suits electricians and maintenance technicians requiring reliable performance.

1/4 Inch Keystone Tip Precision

The single specification that decides fit is the 1/4 inch keystone tip width matched to the screw slot. This tip profile provides a secure engagement that resists cam-out during high-torque applications. Precision machining ensures an exact fit in compatible fasteners. Select this driver only when the screw slot matches this specific width and keystone geometry.

Cushion-Grip Handle and Tip-Ident

The cushion-grip handle delivers greater torque transfer and comfort during extended use, reducing hand fatigue. Tip-Ident marking on the handle quickly identifies the screwdriver type and tip orientation in a crowded tool bag. These features speed up selection and improve control on the job. No additional accessories or software are included with this tool.
