Klein Tools 600-4 Keystone Tip Screwdriver Square Shank

Product Description

The KLEIN TOOLS 600-4 is a heavy-duty flathead screwdriver built with a square shank and a keystone tip, designed for professional tradespeople who need reliable torque in demanding installation and service work. The square shank allows a wrench to be applied directly to the shank for extra turning force when fasteners are seized or require high breakaway torque. A bolster at the handle reinforces the shank-to-handle connection, adding durability under hard use. The 4-inch shank length provides reach in standard access conditions. At 0.3 pounds, it is a lightweight tool suited for all-day use on the job.

This screwdriver is a standard service tool for electricians, HVAC technicians, plumbers, and general trade professionals. It is used wherever slotted fasteners are encountered during equipment installation, panel work, junction box service, or mechanical assembly. The keystone tip profile fits a wide range of common slotted screw heads found in trade applications. The square shank design makes it particularly useful when a fastener is corroded or torque requirements exceed what hand grip alone can deliver.

Key Features

• Square shank accepts an open-end or adjustable wrench for wrench-assisted turning
• Bolster at the handle reinforces the shank for high-torque and hard-use applications
• Keystone tip profile fits standard slotted fasteners common in trade work
• 4-inch shank length for access in typical service scenarios
• Lightweight construction at 0.3 pounds for extended use comfort

Compatibility

Designed as a general-purpose flathead screwdriver for use with standard slotted fasteners encountered in electrical, HVAC, plumbing, and mechanical trade applications.

Installation Notes

This tool is used by licensed electricians, HVAC technicians, plumbers, and other trade professionals for fastener driving and removal. When applying a wrench to the square shank for additional torque, use a properly sized open-end or adjustable wrench and ensure the tip is fully seated in the screw slot to prevent cam-out or tip damage. Inspect the tip for wear or rounding before use on fasteners that require high torque. Follow all applicable job-site safety practices when working near energized equipment.
