DXS Impact Sockets from Ingersoll Rand replace the traditional square drive of other sockets with a spline-type interface for a tighter fit, more load-bearing surface, and easier access to tight spaces. The sockets are made from chrome molybdenum alloy steel, feature a ball nose retention pin for quick, tool-free installation and removal, and come with a lifetime limited warranty. The sockets are available both individually and in four sets: SAE, metric, standard, and deep.
