Bosch Hex Extra Hard Screwdriver Bit

The Bosch Extra Hard Screwdriver Bit in Hex 3mm, 25mm length, comes as a pack of 3. Hex 3mm is a popular size for general hex socket fixings, so this pack is a handy one to keep in the toolbox. The bit is made from S2 Modified Steel and given an optimised heat treatment process, resulting in extra-hard quality for universal use. The 25mm length keeps it compact for everyday tasks. A tapered torsion zone absorbs force and vibrations, coping easily with torque peaks. The ¼-inch external hex shank works with screwdrivers and drill drivers.
