The Bosch PRO 7 Piece Impact Socket 12 Sq. Standard Set from ITS is a strong set of sockets designed for impact wrenches. Made from Chrome-molybdenum steel, these are particularly resistant to high torque. You can use the PRO Impact Socket Set to handle hex screws, bolts, and nuts with your square-drive wrench. Bosch have made the 39mm length sockets in the PRO Impact Socket Set from heat-treated CRMO chrome-molybdenum steel and gave them thick walls to make sure they resist high torque. A black phosphate coating to protects them from rust and corrosion. The sockets are laser-marked and colour-coded so that you can see the one you need right away. They feature a groove and a through hole for securing them on your impact wrench, using our pin and ring whenever you need an extra strong hold. The adapters allow you to use the sockets with impact drivers and hex bits with impact wrenches for any lighter tasks below 80 Nm torque.
