The Heavy-Duty Square Shaft Keystone Cushioned-Grip Screwdriver features a tough, chrome vanadium steel blade and heavy-duty square shank that offers wrench-assisted turning. Its cushion-grip handle is resistant to oil, gas, and water, and helps to prevent slippage offering greater torque as well as superior comfort. Plate chipping is prevented by a vapor-blasted tip, which is also cross-ground to provide a precise and secure fit in the screw slot. The handle ends are also color-coded for quick and easy identification. Screwdriver meets ASTM F1505-01, EN, DIN and IEC 60 900-test standards.
