The Double Ended Screwdriver Bit is highly robust and ideal for heavy duty applications, even withstanding the high power of impact drivers. The bit features an extended torsion zone that makes it extremely sturdy for long-lasting work. S2 Modified Steel and an optimised heat-treatment process provide extra-tough endurance for high performance, including in plant installations or heavy industrial work. The Pick and Click Impact Control Screwdriver Bit Set, 36-Pieces also contains nutsetters as well as the Impact Control Universal Holder Standard Magnetic and the Impact Control Universal Holder Quick Release. These holders are ideal for extra-firm gripping of the bits in universal screwdriving applications with power tools, while the Quick Release Function enables fast and easy bit changes and further supports the strong bit hold. This bit is part of the Bosch Pick and Click system, which enables individually buildable accessory sets for fully customisable bit collections. Click-fitting slots perfectly secure individually purchased packs for a personalised collection and the easy replacement of old packs. It has a 1/4-inch external hex shank for use with drill drivers, screwdrivers, and especially with impact drivers.
