Klein Tools Klein Tools 600-4 Screwdriver, 1/4 In. Keystone Tip, 4 In. Shank

The Klein Tools 600-4 is a heavy-duty screwdriver built for demanding professional and industrial applications. The 1/4-inch keystone tip is precision-machined for exact fit in slotted screws. The square shank design allows wrench-assisted turning for added leverage when extra torque is needed, making this tool ideal for jobs where manual turning alone falls short.

The reinforced bolster strengthens the shank against the stresses of heavy-duty work, while the cushion-grip acetate handle is designed for greater torque and comfort during extended use. Double flanges inside the handle provide a solid, twist-resistant blade anchor that prevents loosening. Heat-treated components ensure durability and reliability on the job.
