Maximum Torque for the Toughest Fastening Jobs

The Klein Tools 600-6 5/16-Inch Keystone Screwdriver is engineered for professionals who encounter stubborn fasteners that demand more than just hand power. Unlike standard round-shank drivers, this tool features a heavy-duty 6-inch square shank. This design allows you to apply a wrench directly to the shaft, generating exceptional torque to break loose rusted, painted, or over-tightened screws without damaging the tool. Precision-machined to exact tolerances, the keystone tip fits securely into screw slots, reducing cam-out and ensuring efficient power transfer during heavy-duty applications.

Beyond brute strength, this screwdriver is built for all-day comfort and long-lasting durability. It features Klein's signature Cushion-Grip™ handle, which provides a soft, non-slip surface for superior control while resisting oil, gas, and water. Inside the handle, integral flanges anchor the blade deeply to prevent twisting or pushing through under pressure. Finished with premium chrome plating for corrosion resistance and equipped with the Tip-Ident® system for quick retrieval from your tool belt, this American-made tool meets or exceeds ASME / ANSI specifications for uncompromising quality.

Key Features

  • Wrench-Assist Design: Heavy-duty square shank allows for the use of a wrench or pliers to apply extra torque.
  • Precision Tip: 5/16-inch Keystone tip is machined for an exact fit to reduce slippage and wear.
  • Cushion-Grip™ Handle: Offers greater torque comfort and a slip-resistant grip for heavy use.
  • Solid Construction: Internal flanges securely anchor the blade inside the handle to provide a twist-resistant foundation.
  • Durable Finish: Special heat-treated shaft with premium chrome plating resists rust and corrosion.
  • Tip-Ident® System: Handle end is marked to easily identify the tip type and orientation in crowded tool bags.
  • Made in the USA: Manufactured to strict standards to meet or exceed ASME / ANSI specifications.

Pro-Tip: The square shank on this screwdriver is designed specifically for wrench assistance. If you encounter a screw that won't budge with hand pressure alone, slide an adjustable wrench or open-end wrench onto the square shaft near the handle. This leverage multiplier allows you to break the torque seal on frozen fasteners safely and easily.

Love it.
Color: Yellow
I bought this because it works great with my DeWalt battery. My driveway was overgrown and it locked up a couple of times which I'm assuming is a safety feature. Once I got the driveway cleaned up it works just fine.

My favorite E edger so far.
Color: Yellow
For a battery powered unit, it was much better than I expected. Powerful enough to do everything in my yard. It beats even some of my previous good gas ones. I did my whole large front yard with a little more than one battery. Pretty good, actually.

Does a good job, and works pretty well. Took weeks to have it delivered.
Works pretty well, seems to be slightly underpowered. I think it would work better if the soil here were drier. The shroud around the blade would probably not jam up with dirt if the soil here is drier. I was constantly having to remove the battery and using a screwdriver to remove the dirt from the shroud. The shroud would work better if it was larger. There is an adjuster that lowers a metal guide that fits up against the concrete that helps you to keep the blade right up to the edge, make sure to lower that guide into place. The 20 Volt Max batteries I used are hard to insert and remove, but mine are aftermarket batteries, and another tool I own is also hard to insert and remove the same batteries.

Good luck with trying to find blades. To work properly one has to find a blade with a center hole of 7/16” diameter OBLONG so it can engage the motor shaft and not spin freely DO NOT BUY THIS REPEAT DO NOT BUY THIS
