Bosch Square Extra Hard Robertson Screwdriver Bit

The Bosch Extra Hard Robertson Screwdriver Bit is a dependable choice for universal square-drive screw-driving on site, in the workshop or around the home. It is made from S2 Modified Steel and an optimised heat treatment process, giving extra-hard quality for adequate performance across a wide range of tasks.

The tapered torsion zone absorbs force and vibrations while you work, so the bit copes easily with torque peaks. A 1/4-inch external hex shank gives a strong connection and maximum torque transmission in three-jaw chucks and 1/4" internal hex tool holders. That makes it suitable for use with both screwdrivers and drill drivers.

The range is available in square drive sizes from R1 to R3, in two bit lengths, and in multiple pack quantities. This makes it easy to match the bit to the screws you use and to keep your kit stocked.
