Bosch Hex Extra Hard Screwdriver Bit

The Bosch Extra Hard Screwdriver Bit in Hex 5mm, 25mm length, comes in a pack of 3. It is intended for larger hex socket fixings, where a bigger tip gives a more secure fit. The bit is made from S2 Modified Steel with an optimised heat treatment process, giving extra-hard quality for universal screw-driving. Its 25mm length keeps it compact and easy to handle. The tapered torsion zone absorbs force and vibrations, coping easily with torque peaks. The ¼-inch external hex shank is designed for screwdrivers and drill drivers.
