Maximum Leverage for Demanding Fasteners: The Heavy-Duty Square Shank Driver Built to Last

Stop slipping on stubborn fasteners and upgrade your layout with the Klein Tools 600-4 1/4-Inch Keystone Tip Screwdriver. Proudly made in the USA, this industrial-grade hand tool is engineered specifically for commercial electricians, HVAC technicians, and industrial maintenance mechanics facing demanding fastened connections. The standout engineering feature is the heavy-duty square shank, which allows professionals to apply a wrench assist directly to the steel blade for maximum wrench-assisted turning torque. Combined with a precision-machined keystone tip that ensures an exact, slip-free fit into slotted screw heads, this driver cleanly transfers raw rotational power without camming out or stripping out hardware heads on critical jobsites.

Built to handle the daily rigors of rugged field work, this premium slotted screwdriver offers unbeatable durability and user control. The high-performance steel shaft is specially heat-treated for long life and chrome-plated to provide a smooth feel and exceptional resistance to rust and jobsite corrosion. Inside the handle, integrated internal flanges create a solid, twist-resistant blade anchor that prevents the shaft from breaking loose under high-torque strains. For all-day comfort, the tool features Klein's iconic Cushion-Grip™ handle layout, offering a comfortable grip and high-friction contact points for optimal twisting leverage. Locating the right tool in a crowded pouch or chest is effortless thanks to the integrated Tip-Ident® system, which clearly marks the handle cap for quick identification of tool type and tip orientation.

Specifications

Pro-Tip: When utilizing a wrench assist on this square shank driver to break free a seized or heavily oxidized screw, apply firm downward pressure on the handle cap with the palm of your hand before turning the wrench. Keeping the keystone tip buried securely in the fastener slot prevents cam-out and ensures the mechanical leverage of your wrench transfers directly to the threads for a clean break without damaging the hardware.
