The Klein Tools 601-4 Cabinet Screwdriver has a 3/16" tip and 4" round shank. It features a narrow cabinet tip to make tight spaces easily acceptable. This Cushion-Grip™ Handle Screwdriver offers the comfort and torque needed for all day work. Its Tip-Ident® quickly identifies screwdriver type and tip orientation, and its 4-inch shaft is heat-treated for greater tool strength. Internal flanges inside the handle provide a solid, twist-resistant blade anchor.
