This extra-hard screwdriver bit is a good choice for general-purpose work. S2-modified steel and an optimized heat treatment process result in above-average hardness for adequate performance in all types of applications. The bit's tapered torsion zone effectively handles torque peaks by absorbing forces and vibrations during screwdriving. It tackles a wide range of tasks. It features a 1/4-inch external hex shank for general screwdriving applications with screwdrivers and power drills.
