Stanley FatMax Screwdriver Parallel has a chrome vanadium steel bar that allows high torque and reduces the risk of tip breakage. The handle is moulded directly to the shaft for a virtually unbreakable bond and the soft grip provides a great grip and reduced fatigue. The smooth domed end offers fast, comfortable spinning action and the large diameter handle offers higher torque when driving wood screws. Parallel tips are ideal if the screw needs to be driven below the material surface.
