Bosch Hex Extra Hard Screwdriver Bit

The Bosch Extra Hard Screwdriver Bit in Hex 8mm, 25mm length, comes as a pack of 3. It is the largest hex size in the range, suited to big hex socket fixings. The bit is made from S2 Modified Steel and given an optimised heat treatment process, resulting in extra-hard quality for universal screw-driving. The 25mm length keeps it compact and easy to control. A tapered torsion zone absorbs force and vibrations, coping easily with torque peaks. The ¼-inch external hex shank is intended for use with screwdrivers and drill drivers.
