Klein Tools 603-3 Phillips Screwdriver No. 1 Tip

Product Description

The KLEIN TOOLS 603-3 is a No. 1 Phillips-tip screwdriver built for electricians, HVAC technicians, and other trade professionals who need a reliable hand tool for daily service work. It features a round shank measuring 3 inches and an overall length of approximately 6.75 inches. The tip is profilated, meaning it is precision machined to achieve more consistent geometric symmetry than conventional Phillips tips. That tighter profile translates to better bit-to-fastener engagement and reduced cam-out during installation and removal tasks.

This screwdriver suits residential and light commercial service work where a compact, No. 1 Phillips driver is called for. Common applications include terminal screw fastening, cover plate installation, and equipment panel work across electrical, HVAC, and plumbing trade environments. The round shank design allows a wrench or pliers to be applied for additional torque when needed.

Key Features

• Profilated Phillips tip precision machined for consistent geometric symmetry
• No. 1 Phillips tip size for small to medium fasteners
• 3-inch round shank with wrench-compatible geometry
• Overall length of approximately 6.75 inches for standard reach
• Lightweight at 0.2 pounds for reduced hand fatigue during extended use

Compatibility

Designed as a standard No. 1 Phillips hand screwdriver suitable for general trade use wherever No. 1 Phillips fasteners are encountered.

Installation Notes

This tool is used by electricians, HVAC technicians, plumbers, and general trade professionals for fastening and removal of No. 1 Phillips screws. Always de-energize electrical equipment and follow lockout/tagout procedures before using hand tools in or around live panels or control boards. Inspect the tip for wear or deformation before use, as a damaged tip increases the risk of fastener damage and cam-out.
