The KLEIN TOOLS 603-7 is a No. 2 Phillips-tip screwdriver designed for professional tradespeople who need consistent, reliable drive engagement on fasteners. The round shank measures 7 inches, and the overall length is approximately 11-5/16 inches. The tip is profilated — precision machined to deliver tighter geometric symmetry than a standard Phillips tip — which reduces cam-out and maintains better contact with fastener heads during repeated use. This screwdriver is a hand tool staple found in the kits of electricians, HVAC technicians, plumbers, and other service trades.
The 603-7 suits a wide range of fieldwork and bench applications where No. 2 Phillips fasteners are common. This includes electrical panel work, equipment installation, enclosure assembly, and general service tasks across residential and light commercial settings. The 7-inch shank provides reach in confined spaces while keeping the tool manageable for all-day use.
Designed for use with standard No. 2 Phillips head fasteners common across electrical, HVAC, plumbing, and general mechanical applications.
This screwdriver is a hand tool intended for use by licensed tradespeople and qualified technicians. Always de-energize electrical equipment and follow lockout/tagout procedures before working on panels or equipment interiors. Use the correct tip size to avoid fastener damage — a worn or mismatched Phillips tip significantly increases cam-out risk. Inspect the tip for wear before use and replace the tool if the tip geometry is visibly degraded.
