Nutsetter and screwdriver bit set containing highly robust bits for heavy duty applications. Screwdriver bits feature an extended torsion zone that make them extremely sturdy for long lasting work, even withstanding the high power of impact drivers. S2 modified steel and an optimised heat-treatment process provide extra-tough endurance for high performance applications, such as in-plant installations or heavy industrial work. Bits have a ¼" external hex shank and are suitable for use with drill drivers, screwdrivers, and especially with impact drivers. Hex shank delivers maximum power transfer in standard three-jaw drills and hexagonal drill driver chucks. Part of the Pick and Click system with click-fitting slots for fully customisable bit collections. Supplied in a plastic holder.
