The KLEIN TOOLS 600-12 12I is a heavy-duty keystone flathead screwdriver built for demanding trade applications. The square shank measures 12 inches and is designed to accept a wrench for increased turning force, making it practical when driving large fasteners into tough materials. The cushion-grip handle provides added torque and extended-use comfort. A tip identification feature on the handle allows technicians to quickly identify the screwdriver type and blade orientation without pulling it out of a tool bag or pouch. This screwdriver is suited for electricians, plumbers, HVAC technicians, and general contractors who require reliable hand tools on the job.
This screwdriver is well suited for residential and commercial trade work where heavy fastener driving is routine. The 12-inch square shank gives the tool reach in deep junction boxes, panels, or equipment enclosures. The wrench-assist capability on the square shank is particularly useful when breaking loose or setting stubborn fasteners that resist standard hand torque. Electricians and multi-trade installers will find this tool applicable across a wide range of service and installation tasks.
Designed as a general-purpose keystone flathead screwdriver suitable for large slotted fasteners encountered in electrical, HVAC, plumbing, and general construction applications.
Always de-energize and lock out electrical circuits before using any screwdriver in or around live panels, breaker boxes, or junction enclosures, in accordance with NFPA 70E safe work practices. Inspect the tip for wear or rounding before use, as a damaged tip can slip and damage fasteners or cause injury. Use only the shank flats with a properly sized wrench when applying extra torque, and avoid using the handle as a striking surface.
