The Bosch Extra Hard Screwdriver Bits are ideal for a wide variety of screwdriving tasks. They are made from S2 modified steel with an optimised heat treatment that results in an extra hard finish. The tapered torsion zone copes easily with torque peaks as it absorbs force and vibrations when screwdriving. It has a 1/4in external hex shank for universal screwdriving with screwdrivers and drill drivers.
