This 8-piece impact socket set features sockets with a 1/2" drive and a length of 78mm. Made from heat-treated, hardened, and tempered chrome-molybdenum steel with a blackened surface phosphating treatment for exceptional strength and durability. Designed for use with all air-powered and battery-powered impact tools. Each socket has a drilled end to facilitate a retaining ball bearing for use on ratchets and breaker bars. The set includes sizes H5, H6, H8, H10, H12, H14, H17, and H19mm. Supplied in a quality blow-molded storage and carry case. The rugged chrome molybdenum construction is drop-forged and heat-treated to cope with the vibration and greater torque generated by impact wrenches. Features a black oxide coating for maximum corrosion resistance and high-visibility laser markings for easier identification.
