Stanley FatMax Screwdriver Pozi PZ2 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 to give a longer life and durability 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.
