Robust insertion of screws! Chromium-molybdenum steel for resistance to Hohem torque You can use the PRO Impact socket wrench insert for cap screws, bolts and nuts with your square drive wrench. We have developed it for screwing in large-scale assembly or other demanding industrial work. The PRO Impact socket wrench insert is made of heat-treated CRMO (chromium-molybdenum) steel and is very resistant to high torques thanks to the thick walls. The black phosphate coating protects it against rust and corrosion. The socket-wrench inserts are labeled and color-coded with a laser, so that you find the right one at a glance. They have a groove and a through hole. For extra strong hold, they can be attached with pen and ring on your impact driver.
