Bosch 19 Piece L Extra Hard Screwdriver Bit Set is a good choice for universal use. The bit´s tapered torsion zone copes easily with torque peaks as it absorbs force and vibrations when screw-driving and thus fulfilling all tasks. It has a 1/4-inch external hex shank and is intended for universal screw-driving with screwdrivers and drill drivers.
