Product Overview. Husky 3/8 in. drive impact sockets are forged from chrome molybdenum alloy steel (Cr-Mo) and designed to withstand rigors of heavy duty auto and industrial use. Size markings have been hard stamped into the sockets for quick and easy identification that will never wear away.
Impact wrenches get their immense torque from a hammering mechanism in the tool that delivers strong concussive blows extremely quickly. When loosening a lug nut you'll notice the socket attached to the impact wrench moving slowly as the lug nut is loosened and then quickly when it's loose.
