Add this must-have Husky 1/4 in. Drive Impact Driver Socket Adapter Set to your DIY or professional toolbox. To be used with impact drivers and sockets, these adapters work on 3 different drive sizes of standard and deep sockets (1/4 in., 3/8 in., and 1/2 in.). For strength and durability, they are made of heat-treated steel and offer a black oxide coating for corrosion resistance. The set quickly converts any power drill or 1/4 in. impact driver into a socket driver to easily tighten or remove fasteners.
