Klein Tools 600-6 Keystone Screwdriver Square Shank

Product Description

The KLEIN TOOLS 600-6 is a heavy-duty flathead screwdriver built for professional tradespeople who demand reliable performance on tough fasteners. It features a 5/16 inch keystone tip and a 6 inch square shank, which allows a wrench to be applied directly to the shank for added torque when driving stubborn screws. A bolster at the handle reinforces the shank junction, reducing the risk of shank failure during high-force applications. Electricians, plumbers, HVAC technicians, and general contractors rely on this type of tool for panel work, conduit fittings, junction box hardware, and other fastener-heavy tasks where standard screwdrivers fall short.

This screwdriver is suited for residential and commercial trade applications where frequent, high-torque driving is required. The square shank design makes it especially practical in tight service situations where impact or wrench assistance is needed to break loose corroded or over-torqued fasteners. The overall length of approximately 10-15/16 inches provides good reach into enclosures and panels without sacrificing control. It is sold individually and is appropriate for any tradesperson carrying a standard tool kit.

Key Features

• Square shank accepts a wrench for added turning force on stubborn fasteners
• Bolster reinforces the shank-to-handle joint for heavy use and impact resistance
• 5/16 inch keystone tip fits a wide range of standard slotted screw heads
• 6 inch shank length provides extended reach into enclosures and panels

Compatibility

Designed as an OEM-style professional-grade replacement or addition for standard flathead screwdriver applications in electrical, plumbing, HVAC, and general mechanical trade work.

Installation Notes

This tool is used by licensed electricians, plumbers, and HVAC technicians across a wide range of fastener-driving tasks. Always de-energize electrical panels and circuits before using any hand tool in or around live components. When using a wrench on the square shank, apply steady controlled force to avoid cam-out or tip damage. Inspect the tip for wear or rounding before each use and replace the screwdriver if the tip no longer seats fully in the screw head.
