Robust insertion of screws! Chromium-molybdenum steel for resistance to Hohem torque You can use the PRO Impact socket set 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 set consists 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. With the adapters you can use the socket wrench inserts with impact screwdrivers and hexagonal bits with impulse screwdrivers for all lighter tasks below 80 Nm of torque.
