Bosch Professional Screwdriver Bits & Sockets Impact Socket

PRO Impact Socket for Robust Screwdriving You can use the PRO Impact Socket to handle hex screws, bolts, and nuts with your square-drive wrench. We designed it to help you with screwdriving tasks in plant installations or other types of heavy industrial work. We made the PRO Impact Socket from heat-treated CRMO (chrome-molybdenum) steel and gave it thick walls to make sure it resists high torque. We added a black phosphate coating to protect it 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.
